细胞社会性 Cell sociology ◆细胞与细胞、细胞与细胞外基质乃至整个 机体的相互作用、相互依存、相互制约即细 胞的社会性。 ◆细跑的生存、生长、分裂、分化等行为必 须在细胞社会中进行。 正常细胞繁殖接受细胞社会的约束,一切有条不紊

Cell sociology Cell-cell interreaction 细胞间直接接触、细胞通过分泌介质相互影响 Cell-ecM interreaction mechanical stresses are transmitted from epithelial cell to cell by cytoskeletal tissue filaments anchored to cell-matrix and cell-cell basal adhesion sites lamina extracellular matrix directly bears mechanical connective stresses of tension and tissue compression collagen fibers Interreaction of cell-cell or cell-ECM
◆ Cell-cell interreaction 细胞间直接接触、细胞通过分泌介质相互影响 ◆ Cell-ECM interreaction Interreaction of cell-cell or cell-ECM Cell sociology
1.1 Cell adhesion and cell Junction The cellular property that mediates the binding is called cell adhesion Many cells in tissues are linked to one another and to the extracellular matrix at specialized contact sites called cell unctions
