Surface membrane-associated regulation of cell assembly, differentiation, and growth.

摘要: The role of the surface membrane in regulating proliferation and differentiation eukaryotic cells is highly complex. Proximal cell-cell interactions are involved, including physical contact via junctional complexes, exfoliation vesicles, proteolytic cleavage membrane-bound precursors, exocytosis soluble proteins (see Fig 5). At another level, expresses receptors other that mediate adhesion, a multistep event may be sufficient to activate some growth-associated genes alter cell shape. evidence indicates together with secreted growth factors, membrane-associated molecules play dynamic multicellular assembly growth.
