Description

Cell Shape: Determinants, Regulation, and Regulatory Role is written to help readers understand cell shape and its regulation. It provides insight into how the shape of a cell is determined at a molecular level. It also discusses how the shape of the cell, as a signal, controls gene expression and modulates intercellular interaction. Divided into four parts encompassing 13 chapters, this volume begins with an overview of the mechanism of shape determination. It then explores how the cytoskeleton, the extracellular matrix, and biochemical force transduction may affect or respond to cell shape control. Other chapters focus on the mechanical modeling of cell shape and the biochemical reactions underlying cell motility. The text also describes the results of the molecular studies that have provided important information on the composition of the cytoskeleton. The final chapter reviews the shape changes that happen during embryogenesis. It also considers how the polarity of the embryo is determined. This book is a valuable resource for biologists, embryologists, and cell biologists.
