Animal Morphogenesis Is Shaped Actively by Adhesion and Cell Migration
As a result of cell division and cell differentiation, a large variety of cells with different shapes and divergent molecular constitutions and makeups appear. In turn, these cells create associations of cells serving a common function: tissues and organs. In cell associations the number, the size, and the shape of the individual cells eventually will determine the shape of the whole association. In contrast to the development of plants, in animals active shaping through intracellular contractile filaments and forces of cohesion and adhesion are observed, and extensive displacement and migration of cells take place.
