The basolateral membrane of the absorptive epithelial cells differs from the microvillus membrane in morphology, biochemical composition, and function. There are intercellular spaces between adjacent cells.

The basolateral surface includes the base (where the cell attaches to underlying epithelium or deeper tissues) and the sides (where the cell connects to its neighbors).

Lateral membranes are the site of contact between epithelial cells, whereas basal membranes connect epithelial cells to the basement membrane, an extracellular matrix layer that lies along the basal surface of the epithelium.

2020年9月8日 · The structural modifications in the basal domain include basal infoldings, the basement membrane, and cell-to-matrix junction. Basal infoldings: the basal cell membrane is thrown into folds, this aims to increase the surface area …

The basolateral membrane contains the proteins common to most plasma membranes while the apical membrane contains a specialized group of membrane proteins. The presence of two different cell surfaces represents an additional targeting problem for epithelial cells [41] .

The basolateral membrane of a polarized cell is the part of the plasma membrane that forms its basal and lateral surfaces, distinct from the apical (or lumenal) surface. This is particularly evident in epithelial cells, but also describes other polarized cells, such as neurons.

Epithelial cells are able to transport substances in one direction across the epithelium because different sets of transporters are localized in either the apical or basolateral membranes. Absorption is the means whereby nutrients such as glucose are …

The basolateral membrane of a polarized cell is the part of the plasma membrane that forms its basal and lateral surfaces, distinct from the apical (or lumenal) surface.

Basolateral membrane refers to the part of a cell membrane that contains various pumps and exchangers responsible for maintaining ion levels, such as Na+ and K+, in cells. AI generated definition based on: Knobil and Neill's Physiology of Reproduction (Fourth Edition), 2015

2022年8月27日 · Basolateral plasma membrane (Science: cell biology) The plasma membrane of epithelial cells that is adjacent to the basal lamina or the adjoining cells of the sheet. Differs both in protein and phospholipid composition from the apical plasma membrane from which it is isolated by tight junctions (zonula occludentes).
