Mechanical Models for Generating Pattern and Form in Development

Abstract

Development of spatial pattern and form is one of the central issues in embryology. The formation of structure in embryology is known as morphogenesis. Pattern generation models are generally grouped together as morphogenetic models. These models provide the embryologist with possible scenarios as to how pattern is laid down and how the embryonic form might be created. Although genes of course play a crucial role in the control of pattern formation, genetics says nothing about the actual mechanisms involved nor how the vast range of pattern and form that we see evolves from a homogeneous mass of dividing cells.
