Abstract
A method for growing epithelial cells in vitro using soluble proteins secreted by 804G rat bladder carcinoma cells. These proteins are able to stimulate cell attachment and hemidesmosome formation in cells grown in contact with the proteins. The purification of these proteins from 804G culture supernatant is greatly facilitated by culturing the cells under low serum conditions.
