Basement membrane layers
웹Basement membranes are thin layers of a specialized extracellular matrix that form the supporting structure on which epithelial and endothelial cells grow, and that surround muscle and fat cells and the Schwann cells of peripheral nerves. One common denominator is that they are always in close appos … 웹2015년 6월 8일 · Alveolar blood-gas barrier: a thin trilamellar membrane composed of three layers: Capillary endothelial cell; Basal lamina; Alveolar Type 1 cell; Short diffusion distance: 0.2-2 µm for the blood-gas interface.
