Abstract
The ability to generate spatial form is a fundamental characteristic of all living organisms, which has been much studied by successive generations of developmental biologists. In recent years increasing numbers of cell biologists have turned their attention to the mechanisms by which cells generate their spatial form. These include the mechanisms that position components in different places within the cell, that specify the position of these components, and that generate the overall shape of these components. These problems are entirely analogous to those studied by developmental biologists, although usually at the level of the whole organism, organ or tissue. Because the organization of all cells is basically similar, it is possible that the concepts and the underlying molecular mechanisms of cell morphogenesis may be highly conserved. In this article we consider the generation of spatial form within the fission yeast cell, focusing on emerging new concepts, which may be applicable to the morphogenesis of other cells.
