title: Cytoarchitecture and cell growth control.
abstract: Appropriate cell-to-substrate adhesion together with SGF stimulation is necessary to initiate and continue cell cycle progression of growth arrested cells. Adhesion-dependent signaling events, which likely occur through integrin receptors specifically organized with cytoskeletal components within focal contacts, can induce expression of specific genes and stimulate quiescent cells into the growth cycle. The mechanisms as to how: (1) cell-to-substrate adhesion complexes are formed and maintained, (2) adhesion-dependent signal transduction events interface with SGF initiated signalling events, (3) adhesion influences expression of growth-state regulated genes, and (4) an appropriate cytoarchitectural environment may coordinate these events to regulate cellular growth are unclear. While it is apparent that defining these mechanisms would be critical to understanding the basic events which control cell growth, many of the mechanisms are just beginning to be addressed and understood.
