PDF-Throughout embryogenesis, cells bud off from develop

ing tissues and move outwards to shape and pattern the complex architecture of prospective organs 1 A similar process occurs in adult life during wound healing and tissue repair when lingering. To perform these processes cells adhere to extracellular matrix components via adhesion receptors forming complexes with componen ts of the cytoskeleton that ultimately affect cell motility differentiation proliferation and survival The Cell Biolabs 624 . - Developmental Genetics.
