    Manuscripts should be submitted online: New users should start by creating an account and then follow the instructions provided. Manuscripts are submitted through the Author Centre. Authors for invited articles should follow the instructions given in the invitation e-mail.

    Preparing the Article
    A Cover Letter should be provided, where authors vouch for the accuracy of the manuscript according to the guidelines given here. This is also the place where authors may inform the editors of any special circumstances or details regarding the submitted material, including prior publication of the material/parts of the material in a minority language. Authors are welcome to recommend reviewers in the cover letter, particularly if they are Cytotherapy editorial board members. Associate Editors should not be recommended as reviewers.

    Please print out the Author Approval form, fill in all details and obtain signatures from all authors. Scan and upload this form together with your manuscript files. Use the File Designation to indicate the correct file category. Only the main manuscript file will be sent to the reviewers for evaluation.

    Manuscript files should be structured as follows: (1) Title page; (2) Abstract; (3) Keywords; (4) Abbreviations; (5) Main text; (6) Acknowledgments; (7) Disclosure of Interest; (8) References; (9) Legends of Figures and Tables; and (10) Tables and/or Figures.

    The Title page should include: (a) Full title (avoid abbreviations in the title); (b) Running title (for page heading, maximum of 50 characters); (c) All contributing authors with full name, title and affiliation; and (d) Corresponding author details with e-mail address (to which all decision letters and page proofs will be communicated).

    Abstract: Should be 250 words or less and divided into subheadings: (1) Background; (2) Methods; (3) Results; (4) Discussion; and (5) Keywords. Only approved abbreviations may be used in the abstract without definition. Review Articles should include a "block style" non-structured abstract.

    Keywords: After the abstract, please include 3-10 keywords placed in alphabetical order and according to the Medical Subject Headings list of Index Medicus.

    Abbreviations: Used in the text should all be explained and listed on a separate page after the Abstract.

    Main text
    The text for original articles should be structured with the following headings: Introduction, Materials and Methods / patients and methods (including statistics, ethics and consent issues), Results, and Discussion.

    Acknowledgements: Include only those who have made a valuable contribution to the work presented but who do not qualify as authors, with their contribution described. This may include a patient population and funding bodies. Use plain language and avoid adjectives. If appropriate, funding for publication, for writing or editorial assistance may be added.

    Disclosure of Interest: Authors are responsible for recognizing and disclosing any conflict of interest, or potential conflict of interest, that may bias their work, or could be perceived to bias their work, and acknowledge all financial support and any other personal connections. Cytotherapy adheres to the ICMJE guidelines, including those on Conflict of Interest and Authorship. Please indicate any activities that apply to the past five years and foreseeable future. Authors must complete the Journal's Conflict of Interest form and upload it with their manuscript and figure files during the electronic submission process. See also

    Clinical trials: Cytotherapy will not publish clinical trial data unless the manuscript indicates that approval by a local ethical committee, and informed consent has been obtained according to the Helsinki Declaration.

    References: in Vancouver style (see details below).

    Manufactured reagents: When referring to manufactured reagents, please list company name, city, state, and country in brackets following the name of the product/item.

    Figure and Table legends: Clearly marked with the heading of each table/figure. Tables can be included in the main document if created with the table tool in the word processing software. The number of tables and figures should be kept to a minimum. There should preferably not be any repetition/overlap of information given in tables/figures/text. Figures should be submitted as separate files in the best possible quality. Read more about accepted formats and quality requirements below.

    Manuscript Style
    The text should be double-spaced with generous margins. Times New Roman in 12 pt size is the preferred font style. Smaller spacing and font may be used for references, tables and figure legends. Subheadings may be used for clarification in the Material and Methods and Results sections, and must clearly differentiate from the main text using appropriate font style.

    Either English or American spelling is accepted if used consistently throughout the manuscript. Authors who are not fluent in English should use the help of a colleague or translator who is proficient in medical English before submitting the manuscript for consideration. The quality of the language is the author's responsibility. All manuscripts will undergo copyediting before printing, but significant language editing will not be undertaken. Poor quality of English masks the possible scientific merit of some papers, and can delay publication or lead to outright rejection of the paper. More on language editing and quality may be found at, and information on language editing services can be found at

    Abbreviations and units
    A phrase is spelled out when used for the first time followed by an appropriate abbreviation in parentheses. Abbreviations must be spelled out in figure legends and footnotes of tables. If the article contains many non-standard abbreviations, a separate list with explanations must be provided. A list of standard abbreviations is given at our website. All values should be expressed in SI units.

    Use of statistics
    The results should be quantified and presented with appropriate indicators of measurement error or uncertainty (e.g. confidence intervals). The mean and standard deviation (SD) should be given at a minimum; a sole reliance on the use of P values is not acceptable. The statistical method(s) and/or package used should also be stated. The Results should be presented in a logical sequence, and the Discussion should commence with a presentation of the major findings of the study and conclude with the implications and/or applications of the findings. Review Articles are structured more freely, yet the above instructions on statistics should be applied, when relevant.

    Figures should be numbered and quoted consecutively in the text. Please capitalize only the first letter of a label, not every word, and define scale bars in figure legends, not on figures. Legends should be intelligible without reference to the text. For illustrations in color in the printed version of the journal, the authors are required to pay the charges at USD 650 for the first color figure, and USD 100 for each additional color figure. However, illustrations may be printed in black and white in the hard copy and published in color in the online version of the journal without charge.

    Format: EPS or TIFF preferred. Resolution: 1200 dpi greyscale mode for black and white images such as graphs and log scales, 600 dpi greyscale mode for images such as gels or blots, and 300 dpi CMYK mode for colour images. A figure should be no larger than 160mm in width and 200mm in height at the appropriate resolution. Figures with resolution lower than specified will not reproduce correctly and could delay publication. Please upload figures images as separate files in Manuscript Central. For more information on submission guidelines for figures, visit

    Tables should be intelligible without reference to the text and should supplement, not duplicate it. Each table should be included in the main manuscript file on a separate page after the references. The legend should be typed above the first line of the table. If a table has to be continued, a second page should be used and all column headings repeated. All tables should be numbered (Roman numerals) and each must have a caption/legend. Footnotes are indicated by using lower case alphabets as superscripts (e.g., Table Ia). P values are given as numbers (not as *, **, ***).

    The total number of references should not exceed 100. Number references consecutively in the order in which they are first mentioned in the text. Identify references in the text, tables and legends by Arabic numerals within parentheses, i.e. (1). References cited in tables and legends to figures should be numbered in accordance with a sequence established by the first identification in the text of the particular table or illustration. See examples below. The titles of the journals should be abbreviated according to the style used in Index Medicus. The reference style is "Vancouver."

    List all authors when 6 or fewer; when 7 or more, list the first six and add 'et al'. If a journal carries continuous pagination throughout a volume the month and issue number are omitted in the reference list. Page numbers are given as "2284-90", not "2284-2290." The use of abstracts in the list of references should be avoided. Manuscripts accepted but not yet published are designated 'in press.' Unpublished observations as well as manuscripts submitted but not yet accepted should be cited in the text only as 'unpublished observations' with the authors' initials, surname and institution as well as the year when the observation was made. The references must be verified by the authors against the original documents.

    Ethics and Consent
    Cytotherapy considers research and publication misconduct to be a serious breach of ethics, and will take such actions as necessary to address such misconduct. Authors should refer to the Committee on Publication Ethics (COPE) and the International Committee of Medical Journal Editors for full information. Authors are also encouraged to visit Elsevier's Ethical Guidelines for Journal Publication.

    Plagiarism and duplicate submission are serious acts of misconduct. Plagiarism is defined as unreferenced use of published or unauthorized use of unpublished ideas, and may occur at any stage of planning, researching, writing, or publication. Plagiarism takes many forms, from 'passing off' another's paper as the author's own paper, to copying or paraphrasing substantial parts of another's paper (without attribution), to claiming results from research conducted by others. Plagiarism in all its forms constitutes unethical publishing behavior and is unacceptable. Duplicate submission/publication occurs when two or more papers, without full cross-reference, share the same hypothesis, data, discussion points, or conclusions.

    Identifying information should not be published in written declarations, photographs or pedigrees. Do not reveal patients' names, initials or hospital numbers, for example in illustrative material. Photographs of human subjects must be accompanied by informed consent of the person(s) concerned and requires that the person should see the manuscript before publication. Facial features must be unrecognizable.

    The Editorial Office may request the authors to supply a PDF copy (or paper copy) of an ethical committee approval for articles describing animal experiments or clinical studies/trials (patients, patient material, medical records), including a verified and official translation of such documents. State in the ethics section that the procedures of the study received ethics approval from the relevant and named national, regional or institutional ethics/review committee(s) responsible for human/animal experimentation. Supply the date of issue and registration number. If no ethics approval was received, explain why, including an explanation as to how the study adhered to the Helsinki Declaration. If deemed necessary by the Editors, cases will be submitted to COPE (Committee on Publication Ethics).
