    Aim and scope

    Experimental Hematology publishes original research reports (regular and fast-track submissions), reviews, perspectives, letters to the editor, and abstracts of the annual meeting of ISEH - International Society for Experimental Hematology. We welcome manuscripts describing basic in vitro and in vivo research centered on normal and malignant hematopoiesis as well as non-malignant hematologic diseases. Submissions focused on non-hematopoietic stem cells (e.g. mesenchymal stem cells, embryonic stem cells and induced pluripotent stems) with potential relevance to hematopoiesis are also welcome, as are studies involving experimental or early phase clinical cell transplantation. Studies employing genomic and systems biology approaches to the study of normal and malignant hematopoiesis are strongly encouraged, as are those employing model organisms.

    Types of articles

    Research articles will be published under the following scientific categories: Stem Cells (hematopoietic, mesenchymal, embryonic and induced pluripotent stem cells); Normal Hematopoiesis (myelopoiesis, erythropoiesis, lymphopoiesis, megakaryocytopoiesis); Malignant Hematopoiesis; Microenvironment and Niche; Systems Biology; Genomics/Proteomics of Hematopoiesis; Immunobiology and Immunotherapy; Gene Therapy; Clinical Investigations (stem cell or other cell transplant related therapies); New Techniques and Technologies.

    Regular Submissions: These are full-length reports of original research. We welcome articles on a range of topics with particular interest in those covering regulation and development of normal hematopoietic stem cells, stem cell expansion and self-renewal; novel sources of hematopoietic cells including embryonic stem cells and reprogrammed induced pluripotent stem cells; hematopoietic progenitors and differentiation control; growth factors/receptors and signal transduction; genomics, transcription factors and epigenetics; mechanisms of hematopoietic transformation; properties of leukemic stem cells and novel therapeutic targets; the hematopoietic niche/microenvironment; homing and engraftment of hematopoietic stem cell; immunotherapy of hematologic malignancy; non-malignant hematopoietic disease; application of model organisms to the study of hematopoiesis, and new techniques/methods and technology for hematopoiesis investigation. Studies centered on cell transplantation, both at the pre-clinical/experimental and early clinical stage are also of high priority.

    Brief communications: We also welcome articles on the same range of topics as outlined for regular submissions, but that can be reported in a shorter format. Brief communications are intended to allow publication of highly significant findings reported concisely, and not of incomplete or preliminary data. As with regular submissions, brief communications are expected to provide mechanistic insights, elucidate novel disease biology or approaches to therapy.

    Brief communications should contain a maximum of 1,500 words exclusive of the abstract, figure legends and references. Format can be as for regular submissions, but a combined Results and Discussion section is encouraged. Only 3 figures/tables and 30 references are allowed.

    Fast-Track Submission: Expedited review will be offered, on request, for research articles falling within the scope of the topics suitable for Experimental Hematology that have been previously considered by other top ranked journals and for which the previous reviewers' comments and the appropriate responses can be provided. Decisions will be made by the Editor-in-Chief in consultation by one or more members of the Editorial Board within 7-10 days of submission.

    Reviews and Perspectives: Review Articles are summaries of a topic of interest to Experimental Hematology's broad readership. Perspectives are articles discussing significant topics and controversies relevant to the field of hematology and stem cells, generally from a more personal or opinion-based standpoint than a Review Article. Review Articles and Perspectives are welcomed by the journal and are generally solicited by the Editor-in-Chief; however, authors wishing to submit an unsolicited Review Article or Perspectives are invited to contact the editorial office prior to submission.

    Letters to the Editor: They may relate to material published in the journal, to ISEH business, editorial policy, or anything else pertinent to the field of experimental hematology and/or stem cells. A letter that addresses an article published in this journal should be submitted as soon as possible, no later than two calendar months after publication. Such a letter will be sent to the authors of that paper for a possible reply. All letters and their replies are published at the editor's discretion and are subject to peer-review. Letters should not exceed 1,000 words, must have no title page, no abstract, no headings throughout the text, and no Materials and Methods section. One black and white figure or one table can be included, and no more than 10 references may be used.

    Charges to author

    Authors pay the following charges:

    1. Experimental Hematology requires a submission fee of US $50 to process Regular Submissions (not applicable for Letters to the Editor or Invited Review articles). Current members of ISEH are not required to pay the submission fee when they are the corresponding author of the submission. You may pay by check or credit card. If paying by check, please make checks payable to the ISEH and mail to the Editorial Office address listed at the end of this document. To pay the submission fee by credit card please click on the manuscript submission fee link on the EES homepage ( http://ees.elsevier.com/exphem/). Please note that we cannot release the editorial decision if we have not received the submission fee.
    2. Page charges for manuscripts (as of the June 2003 issue) US $50 per page for the first eight published pages or portions thereof, and US $160 for each additional page over eight or portion thereof, plus tax (except for employees of nonprofit institutions who provide tax-exempt numbers at time of payment). Current members of ISEH are not required to pay the page charges when they are the corresponding author of the submission.
    3. Expense for color reproduction of figures: US $650 for the first figure and US $100 for each additional figure, plus tax (except for employees of nonprofit institutions who provide tax-exempt numbers at time of payment). If, together with your accepted article, you submit usable color figures then Elsevier will ensure, at no additional charge, that these figures will appear in color on the Web (e.g., ScienceDirect and other sites) regardless of whether or not these illustrations are reproduced in color in the printed version. For color reproduction in print, you will receive information regarding the costs from Elsevier after receipt of your accepted article. Please indicate your preference for color: in print or on the Web only. For further information on the preparation of electronic artwork, please see http://www.elsevier.com/artworkinstructions.
    4. Expense for offprints. The publisher will send the corresponding author the price quotation with the page proofs.

    Review process and policies

    Each submitted manuscript will normally undergo peer review by at least two editorial board members or other experts designated by the editor-in-chief or associate editor in charge of the manuscript's review. Authors' names will be seen by reviewers, but reviewers' names will not be disclosed to the authors. A paper can be rejected without undergoing the peer review process if the editor determines that the content is inappropriate for the journal. Authors usually receive the editorial decision within 4 to 6 weeks of their manuscript's arrival at the editorial office.
    The editorial office assigns a manuscript number and acknowledges receipt of submission within 3 days of receipt. Papers submitted by editors or editorial board members are subjected to the same rigorous standards as other manuscripts. An editor who submits a manuscript for consideration does not have access to the reviewers' identities or their confidential remarks for that submission.

    Ethics in publishing

    For information on Ethics in publishing and Ethical guidelines for journal publication see http://www.elsevier.com/publishingethics and http://www.elsevier.com/journal-authors/ethics.

    Human and animal rights

    If the work involves the use of animal or human subjects, the author should ensure that the work described has been carried out in accordance with The Code of Ethics of the World Medical Association (Declaration of Helsinki) for experiments involving humans http://www.wma.net/en/30publications/10policies/b3/index.html; EU Directive 2010/63/EU for animal experiments http://ec.europa.eu/environment/chemicals/lab_animals/legislation_en.htm; Uniform Requirements for manuscripts submitted to Biomedical journals http://www.icmje.org. Authors should include a statement in the manuscript that informed consent was obtained for experimentation with human subjects. The privacy rights of human subjects must always be observed.

    Conflict of interest policy

    A conflict of interest exists when an author, reviewer, or editor has financial or personal relationships with other persons or organizations that may inappropriately influence or bias his or her actions. There is a potential for a conflict of interest whether or not an individual believes that a relationship affects his or her scientific judgment. Conflicts can occur as the result of employment, consultancies, stock ownership, honoraria, paid expert testimony or opinions, personal and family relationships, or academic competitive pressures. All participants in the peer review and publication process must disclose all relationships that could be viewed as a potential conflict of interest.

    Potential Author Conflicts

    Authors should disclose at the time of manuscript submission all financial and interpersonal relationships that could be viewed as presenting a potential conflict of interest. These include, but are not limited to, any financial relationship that involves conditions or tests or treatments discussed in the manuscript or alternatives to tests or treatments. Authors should disclose information even when there is a question as to whether a relationship constitutes a conflict. Potential conflicts should be listed for each author on the page following the title page; a summary of relevant information will be published with the manuscript.

    Authorship of editorials and reviews requires interpretation of the literature and therefore is inherently subject to bias, thus authors of such manuscripts should not have a significant financial interest in the subject matter of the manuscript.

    Submission declaration

    Submission of an article implies that the work described has not been published previously (except in the form of an abstract or as part of a published lecture or academic thesis or as an electronic preprint, see http://www.elsevier.com/postingpolicy), that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere including electronically in the same form, in English or in any other language, without the written consent of the copyright-holder.

    Authorship

    All authors should have made substantial contributions to all of the following: (1) the conception and design of the study, or acquisition of data, or analysis and interpretation of data, (2) drafting the article or revising it critically for important intellectual content, (3) final approval of the version to be submitted.

    Changes to authorship

    This policy concerns the addition, deletion, or rearrangement of author names in the authorship of accepted manuscripts:
    Before the accepted manuscript is published in an online issue: Requests to add or remove an author, or to rearrange the author names, must be sent to the Journal Manager from the corresponding author of the accepted manuscript and must include: (a) the reason the name should be added or removed, or the author names rearranged and (b) written confirmation (e-mail, fax, letter) from all authors that they agree with the addition, removal or rearrangement. In the case of addition or removal of authors, this includes confirmation from the author being added or removed. Requests that are not sent by the corresponding author will be forwarded by the Journal Manager to the corresponding author, who must follow the procedure as described above. Note that: (1) Journal Managers will inform the Journal Editors of any such requests and (2) publication of the accepted manuscript in an online issue is suspended until authorship has been agreed.
    After the accepted manuscript is published in an online issue: Any requests to add, delete, or rearrange author names in an article published in an online issue will follow the same policies as noted above and result in a corrigendum.

    Manuscript length

    Write succinctly. Authors are urged to keep the word count of their papers (excluding references, figure legends, and tables) to less than 3,600 words. Longer papers of scientific merit will not be excluded from publication, but should still be as concise as possible.

    NEW SUBMISSIONS

    Submission to this journal proceeds totally online and you will be guided stepwise through the creation and uploading of your files. The system automatically converts your files to a single PDF file, which is used in the peer-review process.
    As part of the Your Paper Your Way service, you may choose to submit your manuscript as a single file to be used in the refereeing process. This can be a PDF file or a Word document, in any format or lay-out that can be used by referees to evaluate your manuscript. It should contain high enough quality figures for refereeing. If you prefer to do so, you may still provide all or some of the source files at the initial submission. Please note that individual figure files larger than 10 MB must be uploaded separately.

    References

    There are no strict requirements on reference formatting at submission. References can be in any style or format as long as the style is consistent. Where applicable, author(s) name(s), journal title/book title, chapter title/article title, year of publication, volume number/book chapter and the pagination must be present. Use of DOI is highly encouraged. The reference style used by the journal will be applied to the accepted article by Elsevier at the proof stage. Note that missing data will be highlighted at proof stage for the author to correct.

    Formatting requirements

    There are no strict formatting requirements but all manuscripts must contain the essential elements needed to convey your manuscript, for example Abstract, Keywords, Introduction, Materials and Methods, Results, Conclusions, Artwork and Tables with Captions.
    If your article includes any Videos and/or other Supplementary material, this should be included in your initial submission for peer review purposes.
    Divide the article into clearly defined sections.

    Figures and tables embedded in text
    Please ensure the figures and the tables included in the single file are placed next to the relevant text in the manuscript, rather than at the bottom or the top of the file.

    REVISED SUBMISSIONS

    Use of word processing software
    Regardless of the file format of the original submission, at revision you must provide us with an editable file of the entire article. Keep the layout of the text as simple as possible. Most formatting codes will be removed and replaced on processing the article. The electronic text should be prepared in a way very similar to that of conventional manuscripts (see also the Guide to Publishing with Elsevier: http://www.elsevier.com/guidepublication). See also the section on Electronic artwork.
    To avoid unnecessary errors you are strongly advised to use the 'spell-check' and 'grammar-check' functions of your word processor.

    Article structure

    Subdivision - unnumbered sections
    Divide your article into clearly defined sections. Each subsection is given a brief heading. Each heading should appear on its own separate line. Subsections should be used as much as possible when cross-referencing text: refer to the subsection by heading as opposed to simply 'the text'.

    Introduction
    State the objectives of the work and provide an adequate background, avoiding a detailed literature survey or a summary of the results.

    Material and methods
    Provide sufficient detail to allow the work to be reproduced. Methods already published should be indicated by a reference: only relevant modifications should be described.

    Results
    Results should be clear and concise.

    Discussion
    This should explore the significance of the results of the work, not repeat them. A combined Results and Discussion section is often appropriate. Avoid extensive citations and discussion of published literature.

    Appendices
    If there is more than one appendix, they should be identified as A, B, etc. Formulae and equations in appendices should be given separate numbering: Eq. (A.1), Eq. (A.2), etc.; in a subsequent appendix, Eq. (B.1) and so on. Similarly for tables and figures: Table A.1; Fig. A.1, etc.

    Essential title page information

    Title. Concise and informative. Titles are often used in information-retrieval systems. Avoid abbreviations and formulae where possible. The title should accurately reflect the manuscript's content. If the main species used in the study is not human, the species should be included in the title.
    Author names and affiliations. Where the family name may be ambiguous (e.g., a double name), please indicate this clearly. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name and, if available, the e-mail address of each author.
    Corresponding author. Clearly indicate who will handle correspondence at all stages of refereeing and publication, also post-publication. Provide the corresponding author's courtesy title (Prof. or Dr.), full name, and credentials (MD, Phd). Ensure that phone numbers (with country and area code) are provided in addition to the e-mail address and the complete postal address. Contact details must be kept up to date by the corresponding author. Provide contact information for offprints if different from that of the corresponding author.
    Present/permanent address. If an author has moved since the work described in the article was done, or was visiting at the time, a 'Present address' (or 'Permanent address') may be indicated as a footnote to that author's name. The address at which the author actually did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.
    Category for the Table of Contents. Provide the category that best describes the manuscript's topic: Stem Cells (hematopoietic, mesenchymal, embryonic and induced pluripotent stem cells); Normal Hematopoiesis (myelopoiesis, erythropoiesis, lymphopoiesis, megakaryocytopoiesis); Malignant Hematopoiesis; Microenvironment and Niche; Systems Biology; Genomics/Proteomics of Hematopoiesis; Immunobiology and Immunotherapy; Gene Therapy; Clinical Investigations (stem cell or other cell transplant related therapies); New Techniques and Technologies.
    Word count. Supply the paper's word count excluding references, figure legends, and tables.

    For manuscripts about clinical studies, use the category of "Clinical Investigation." If your manuscript's topic does not fit within one of these categories, it may not be within the journal's scope. Contact the editorial office for confirmation before submitting the manuscript.

    Abstract

    A concise and factual abstract is required. The abstract should state briefly the purpose of the research, the principal results and major conclusions. An abstract is often presented separately from the article, so it must be able to stand alone. For this reason, References should be avoided, but if essential, then cite the author(s) and year(s). Also, non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself.

    The abstract should be a continuous narrative (not broken into subheadings) and consist of no more than 250 words. Please include a short list of key words. Where possible, consider using MESH terms. For a list of MESH terms please visit http://www.nlm.nih.gov/mesh/.

    Graphical abstract

    A Graphical abstract is optional and should summarize the contents of the article in a concise, pictorial form designed to capture the attention of a wide readership online. Authors must provide images that clearly represent the work described in the article. Graphical abstracts should be submitted as a separate file in the online submission system. Image size: Please provide an image with a minimum of 531 × 1328 pixels (h × w) or proportionally more. The image should be readable at a size of 5 × 13 cm using a regular screen resolution of 96 dpi. Preferred file types: TIFF, EPS, PDF or MS Office files. See http://www.elsevier.com/graphicalabstracts for examples.
    Authors can make use of Elsevier's Illustration and Enhancement service to ensure the best presentation of their images also in accordance with all technical requirements: Illustration Service.

    Highlights

    Highlights are mandatory for this journal. They consist of a short collection of bullet points that convey the core findings of the article and should be submitted in a separate file in the online submission system. Please use 'Highlights' in the file name and include 3 to 5 bullet points (maximum 85 characters, including spaces, per bullet point). See http://www.elsevier.com/highlights for examples.

    Acknowledgments

    If authors wish to express thanks or acknowledge substantive contributions or assistance of individuals who are not authors, this should be included in the Acknowledgments section after the manuscript text and before the reference list. Authors are responsible for informing all named individuals/parties that they are being mentioned in their submitted manuscript and obtaining their approval prior to publication.

    Units

    Follow internationally accepted rules and conventions: use the international system of units (SI). If other units are mentioned, please give their equivalent in SI.

    Math formulae

    Present simple formulae in the line of normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y. In principle, variables are to be presented in italics. Powers of e are often more conveniently denoted by exp. Number consecutively any equations that have to be displayed separately from the text (if referred to explicitly in the text).

    Footnotes

    Footnotes should be used sparingly. Number them consecutively throughout the article. Many wordprocessors build footnotes into the text, and this feature may be used. Should this not be the case, indicate the position of footnotes in the text and present the footnotes themselves separately at the end of the article. Do not include footnotes in the Reference list.
    Table footnotes
    Indicate each footnote in a table with a superscript lowercase letter.

    Artwork

    Figures that are grouped together must match in size, particularly in height, and be uniform in style and size of lettering. Supply a scale bar with photomicrographs.

    Proofread all text in the figures and ensure that all figure components are clearly distinguishable from each other (e.g., bar graph hatchings). Ensure that the body of the paper does not repeat data reported in figures.

    Electronic artwork
    General points
    • Make sure you use uniform lettering and sizing of your original artwork.
    • Preferred fonts: Arial (or Helvetica), Times New Roman (or Times), Symbol, Courier.
    • Number the illustrations according to their sequence in the text.
    • Use a logical naming convention for your artwork files.
    • Indicate per figure if it is a single, 1.5 or 2-column fitting image.
    • For Word submissions only, you may still provide figures and their captions, and tables within a single file at the revision stage.
    • Please note that individual figure files larger than 10 MB must be provided in separate source files.
    A detailed guide on electronic artwork is available on our website:
    http://www.elsevier.com/artworkinstructions.
    You are urged to visit this site; some excerpts from the detailed information are given here.
    Formats
    Regardless of the application used, when your electronic artwork is finalized, please 'save as' or convert the images to one of the following formats (note the resolution requirements for line drawings, halftones, and line/halftone combinations given below):
    EPS (or PDF): Vector drawings. Embed the font or save the text as 'graphics'.
    TIFF (or JPG): Color or grayscale photographs (halftones): always use a minimum of 300 dpi.
    TIFF (or JPG): Bitmapped line drawings: use a minimum of 1000 dpi.
    TIFF (or JPG): Combinations bitmapped line/half-tone (color or grayscale): a minimum of 500 dpi is required.
    Please do not:
    • Supply files that are optimized for screen use (e.g., GIF, BMP, PICT, WPG); the resolution is too low.
    • Supply files that are too low in resolution.
    • Submit graphics that are disproportionately large for the content.

    Color artwork
    Please make sure that artwork files are in an acceptable format (TIFF (or JPEG), EPS (or PDF), or MS Office files) and with the correct resolution. If, together with your accepted article, you submit usable color figures then Elsevier will ensure, at no additional charge, that these figures will appear in color on the Web (e.g., ScienceDirect and other sites) regardless of whether or not these illustrations are reproduced in color in the printed version. For color reproduction in print, you will receive information regarding the costs from Elsevier after receipt of your accepted article. Please indicate your preference for color: in print or on the Web only. For further information on the preparation of electronic artwork, please see http://www.elsevier.com/artworkinstructions.
    Please note: Because of technical complications which can arise by converting color figures to 'gray scale' (for the printed version should you not opt for color in print) please submit in addition usable black and white versions of all the color illustrations.

    Illustration services

    Elsevier's WebShop (http://webshop.elsevier.com/illustrationservices) offers Illustration Services to authors preparing to submit a manuscript but concerned about the quality of the images accompanying their article. Elsevier's expert illustrators can produce scientific, technical and medical-style images, as well as a full range of charts, tables and graphs. Image 'polishing' is also available, where our illustrators take your image(s) and improve them to a professional standard. Please visit the website to find out more.

    Figure captions
    Ensure that each illustration has a caption. A caption should comprise a brief title (not on the figure itself) and a description of the illustration. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.

    Tables

    Begin each table on a separate page. Number tables consecutively in accordance with their appearance in the text. Place footnotes to tables below the table body and indicate them with symbols in this order: . Avoid vertical rules. Be sparing in the use of tables and ensure that the data presented in tables do not duplicate results described elsewhere in the article.

    References

    Citation in text
    Please ensure that every reference cited in the text is also present in the reference list (and vice versa). Any references cited in the abstract must be given in full. Unpublished results and personal communications are not recommended in the reference list, but may be mentioned in the text. If these references are included in the reference list they should follow the standard reference style of the journal and should include a substitution of the publication date with either 'Unpublished results' or 'Personal communication'. Citation of a reference as 'in press' implies that the item has been accepted for publication.

    Reference links
    Increased discoverability of research and high quality peer review are ensured by online links to the sources cited. In order to allow us to create links to abstracting and indexing services, such as Scopus, CrossRef and PubMed, please ensure that data provided in the references are correct. Please note that incorrect surnames, journal/book titles, publication year and pagination may prevent link creation. When copying references, please be careful as they may already contain errors. Use of the DOI is encouraged.

    Web references
    As a minimum, the full URL should be given and the date when the reference was last accessed. Any further information, if known (DOI, author names, dates, reference to a source publication, etc.), should also be given. Web references can be listed separately (e.g., after the reference list) under a different heading if desired, or can be included in the reference list.

    References in a special issue
    Please ensure that the words 'this issue' are added to any references in the list (and any citations in the text) to other articles in the same Special Issue.

    Reference formatting
    There are no strict requirements on reference formatting at submission. References can be in any style or format as long as the style is consistent. Where applicable, author(s) name(s), journal title/book title, chapter title/article title, year of publication, volume number/book chapter and the pagination must be present. Use of DOI is highly encouraged. The reference style used by the journal will be applied to the accepted article by Elsevier at the proof stage. Note that missing data will be highlighted at proof stage for the author to correct. If you do wish to format the references yourself they should be arranged according to the following examples:

    Reference style
    Include only published materials or those accepted for publication (in press) in the reference list. Cite references in numerical order according to first mention in the text. Verify all entries against original sources, especially journal titles, publication dates, accents, diacritical marks, and spelling in languages other than English. All listed references must be cited in the text.

    Journal titles should be abbreviated according to titles listed in Index Medicus. Cite abstracts only if they are the sole source. References should include complete page ranges. Follow these models when organizing references:

    1. For a journal article with up to 6 authors, list all authors:
      Fraser ST, Ogawa M, Yu RT, Nishikawa S, Yoder MC, Nishikawa S-I. Definitive hematopoietic commitment within the embryonic vascular endothelial-caderin+ population. Exp Hematol. 2002;30:1061-1069.
    2. For a journal article with more than 6 authors, list the first 3 authors, followed by et al.:
      Berries VM, Dooner GJ, Nowakowski G, et al. The molecular basis for the cytokine-induced defect in homing and engraftment of hematopoietic stem cells. Exp Hematol. 2001;29:1326-1335.
    3. For a journal article in press:
      Riley RL, Knowles J, King AM. Levels of E2A protein expression in B cell precursors are stage-dependent and inhibited by stem cell factor (c-kit ligand). Exp Hematol. In press.
    4. For a chapter in a book:
      Munshi NC, Tricot G, Barlogie B. Plasma cell neoplasms. In: DeVita Jr. VT, Hellman S, Rosenberg SA, eds. Cancer: Principles & Practice of Oncology, 6th ed. Philadelphia: Lippincott Williams & Wilkins; 2001. p. 2491-2493.
    5. For an abstract or letter:
      Roberts A, Croker B, Handman E, Williams D, Tarlinton D. Rac2 Regulates T and B Lymphocyte Chemotaxis, Distribution and Function [abstract]. Exp Hematol. 2002;30(suppl 1):143. Abstract 427.

    For other formats, please follow the recommendations of the International Committee of Medical Journal Editors at http://www.icmje.org/ . (this will help those individuals utilizing referencing software.)

    Unpublished observations and personal communications cannot be included in the References section, although they may be cited in the text as "(unpublished data, year)." Papers that rely on such citations for details that are essential for critical review of the manuscript may be rejected. For personal communications, the permission of the individual who communicated the data is required.

    Video data

    Elsevier accepts video material and animation sequences to support and enhance your scientific research. Authors who have video or animation files that they wish to submit with their article are strongly encouraged to include links to these within the body of the article. This can be done in the same way as a figure or table by referring to the video or animation content and noting in the body text where it should be placed. All submitted files should be properly labeled so that they directly relate to the video file's content. In order to ensure that your video or animation material is directly usable, please provide the files in one of our recommended file formats with a preferred maximum size of 50 MB. Video and animation files supplied will be published online in the electronic version of your article in Elsevier Web products, including ScienceDirect: http://www.sciencedirect.com. Please supply 'stills' with your files: you can choose any frame from the video or animation or make a separate image. These will be used instead of standard icons and will personalize the link to your video data. For more detailed instructions please visit our video instruction pages at http://www.elsevier.com/artworkinstructions. Note: since video and animation cannot be embedded in the print version of the journal, please provide text for both the electronic and the print version for the portions of the article that refer to this content.

    Supplementary data

    Elsevier accepts electronic supplementary material to support and enhance your scientific research. Supplementary files offer the author additional possibilities to publish supporting applications, high-resolution images, background datasets, sound clips and more. Supplementary files supplied will be published online alongside the electronic version of your article in Elsevier Web products, including ScienceDirect: http://www.sciencedirect.com. In order to ensure that your submitted material is directly usable, please provide the data in one of our recommended file formats. Authors should submit the material in electronic format together with the article and supply a concise and descriptive caption for each file. For more detailed instructions please visit our artwork instruction pages at http://www.elsevier.com/artworkinstructions.

    Style guidelines

    Abbreviations: All abbreviations must be defined the first time that they are used in the text.

    Distribution of reagents: By publishing in this journal, authors imply that they will make freely available to other academic researchers any easily provided materials (e.g., cells, clones of cells, antibodies, DNA probes, nucleic acid sequences, or genetic strains of animals) that were used in the research reported and that are not available from commercial suppliers.

    Drugs: Trade names, spelled exactly as trademarked and with the initial letter capitalized, may be used after a drug has been identified once by its generic name or by its systematic chemical name. Unfamiliar compounds other than drugs must also be designated, when first issued, by their correct systematic names. Systematic chemical names should conform to the usage given in the indexes of Chemical Abstracts.

    Human Experimentation: In experimental studies with human subjects, details of age, race, and sex of the subject must be included. There must also be a statement that informed consent was obtained from the subjects and that the investigations had been approved by an institutional Human Research Committee. In addition, safeguards for protection of the rights of minors and mentally impaired subjects should be stated. In all material, patients must be identified by number or serial letter and not by initials or names. If the manuscript requires photographs of faces or other identifiable body parts or detailed case descriptions, authors must obtain written consent from the identifiable subject and provide a copy of the permission with the manuscript upon submission.

    Manufacturers: Include the name of the pharmaceutical or equipment company, as well as the city, state or province, and country, in parentheses after the first mention of every material used.

    Mathematical Notation: Use typewritten letters, numbers, and symbols whenever possible. Identify boldface, script letters, etc., at their first occurrence. Distinguish between one and the letter "I" and zero and the letter "O" whenever confusion might result.

    Any data previously published in any form (except abstracts) must be clearly identified as such.

    Measurements: Use chapter 11.12 of AMA Manual of Style, 9th ed. Use metric system and Celsius degrees; use L for liter.

    Nomenclature and Symbols: Follow the recommendations of the International Union of Pure and Applied Chemistry (IUPAC) and the International Union of Biochemistry (IUB). In respect to molecular regulators of hemopoiesis that are either essential for proliferation and differentiation of a given cell line or potentiate the action of a specific regulator, sufficient information should be given in respect to its molecular weight, chemical characteristics, stability, resistance to enzymatic digestion, method of assay, etc., so that others can appreciate the basic properties. When a regulatory molecule has been purified to homogeneity, sequenced, cloned, and produced as a pure entity, the name then given to the humoral regulator should be used. When there are numerous synonyms, these should be listed once. Until there is a consensus in respect to nomenclature, authors may use the names they prefer.

    Statistical Analyses: In respect to bioassay or radioimmunoassay, potency estimates should be accompanied by a measure of the precision of these estimates. Both bioassays and radioimmunoassays should be precision-related to within-assay variability and to the variability measurements or subsequent independent assays. When data are insufficient to determine whether the data conform to a normal or other distribution, it is more appropriate to use nonparametric tests of significance. Manuscripts must describe novel methods, models, and approaches to statistical analysis concisely, but in sufficient detail to allow evaluation of the results reported.

    Recombinant DNA: With the use of "recombinant" material in research, particularly with recombinant viral vectors that may infect human cells, investigators must include a statement regarding the containment category of genetically engineered organisms. Procedures and safeguards must be specified for the construction and handling of recombinant DNA molecules and organisms and viruses containing recombinant DNA.

    Use of the Digital Object Identifier

    The Digital Object Identifier (DOI) may be used to cite and link to electronic documents. The DOI consists of a unique alpha-numeric character string which is assigned to a document by the publisher upon the initial electronic publication. The assigned DOI never changes. Therefore, it is an ideal medium for citing a document, particularly 'Articles in press' because they have not yet received their full bibliographic information. Example of a correctly given DOI (in URL format; here an article in the journal Physics Letters B):
    http://dx.doi.org/10.1016/j.physletb.2010.09.059
    When you use a DOI to create links to documents on the web, the DOIs are guaranteed never to change.

    Proofs

    One set of page proofs (as PDF files) will be sent by e-mail to the corresponding author (if we do not have an e-mail address then paper proofs will be sent by post) or, a link will be provided in the e-mail so that authors can download the files themselves. Elsevier now provides authors with PDF proofs which can be annotated; for this you will need to download Adobe Reader version 9 (or higher) available free from http://get.adobe.com/reader. Instructions on how to annotate PDF files will accompany the proofs (also given online). The exact system requirements are given at the Adobe site: http://www.adobe.com/products/reader/tech-specs.html.
    If you do not wish to use the PDF annotations function, you may list the corrections (including replies to the Query Form) and return them to Elsevier in an e-mail. Please list your corrections quoting line number. If, for any reason, this is not possible, then mark the corrections and any other comments (including replies to the Query Form) on a printout of your proof and return by fax, or scan the pages and e-mail, or by post. Please use this proof only for checking the typesetting, editing, completeness and correctness of the text, tables and figures. Significant changes to the article as accepted for publication will only be considered at this stage with permission from the Editor. We will do everything possible to get your article published quickly and accurately – please let us have all your corrections within 48 hours. It is important to ensure that all corrections are sent back to us in one communication: please check carefully before replying, as inclusion of any subsequent corrections cannot be guaranteed. Proofreading is solely your responsibility. Note that Elsevier may proceed with the publication of your article if no response is received.
