Fibroblast surface antigen (SF antigen, SFA) is a major glycoprotein antigen detected in connective tissue cells (primitive mesenchymal cells, fibroblasts, and astroglial cells). In this study the expression of SFA was followed during differentiation of the mesenchymal cells of the mouse metanephros and during heterokaryon formation produced by Sendai-virus induced fusion of human fibroblasts and chick red blood cells. It was demonstrated by immunofluorescence that SFA was lost from the kidney mesenchymal cells when they differentiate into epithelial cells of the secretory tubuli. During this process SFA became detectable in the basement membrane formed around the tubuli. In cell fusion experiments human SFA which was present as fibrillar network on the surface of cultured fibroblasts, was gradually lost from the heterokaryons when the incorporated chick nuclei became activated. These two sets of experiments indicate that SFA can be used as a phenotypic marker of cytodifferentiation. |
