Intercellular Communication: Renal, Urinary Bladder, Sensory, and Salivary Gland Cells.

摘要: In four epithelial cell systems (salivary gland, renal, urinary bladder, and sensory cells) cells are interconnected as far much of their ion content is concerned. the salivary gland renal epithelia, all epithelium interconnected; communication between a given any its nearest neighbors equally good. bladder appears to be more restricted, manifesting itself in chains connected former, small groups latter. The permeability membrane at junction several orders magnitude greater than it surface bordering exterior cells. Each ensemble functions system with fairly continuous cytoplasmic core bounded by diffusion barrier which along entire outer system. As result, ions move rather freely from cell, but not interior exterior. Intercellular least three epithelia associated presence certain close-junctional complexes.
