Fibronectin synthesis by epithelial crypt cells of rat small intestine.

Abstract

Synthesis of fibronectin in an epithelial cell line (IEC-6) established from rat small intestine was demonstrated by using immunofluorescence, radioimmunoassay, and collagen-binding. Internally labeled radioactive fibronectin isolated from the IEC-6 cells gave a single main band in sodium dodecyl sulfate/polyacrylamide gel electrophoresis under reducing… (More)
