Abstract :

The clone HT29-D4 can be induced to differentiate into enterocytelike cells, by simply removing glucose from culture medium. In this report, we used the HT29-D4 model to study the membrane segregation of the EGF receptor on epithelial intestinal cells. Differentiated and undifferentiated cells displayed a single class of EGF binding sites with similar dissociation constants. However, differentiation of HT29-D4 led to a 3-fold decrease in the total number of EGF binding sites, while the number of TGF-I binding sites was unchanged.
