Abstract

The pattern of cell membrane collagen-binding proteins was analysed by affinity chromatography with collagen types I, III and IV columns. We have found that connective tissue cells have three polypeptides which are able to recognize the types of collagen. These proteins have molecular weights 130, 190, and 250 kDa (reduced) according to SDS-PAGE. Proteins with M. W. 130 and 250 kDa show high affinity to collagen type III and IV, but not to collagen type I. Protein with M. W. 190 kDa binds collagen type I only. The distribution of these proteins between cells from various tissues strongly correlates with the set of collagen types interacting with cells in the intact tissue.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
