Glycocalyx

Japanese: glycocalyx

...In addition, there is interaction between the three types of fibrous structures that make up the cytoskeleton, and it is thought that they mutually regulate the structure and function of the entire cell (Figure).
[Cell surface structure]
The cell membrane surface that faces the extracellular fluid has a hydrophilic layer called glycocalyx, which is made up of protruding glycans. The differences in the arrangement of various monosaccharides in glycans clearly indicate the differences between organisms and cell types.

From [Epithelium]

…The side of an epithelial cell that faces the cavity is called the upper part, and it often has microvilli, which are projections of the cytoplasm. The surface of the cell is covered with glycocalyx. In the formation of vertebrate organs, the epithelium plays an important role in the formation of the neural tube, and the interaction between the epithelium and the mesenchyme leads to the differentiation of higher organs. …
