Effects of TGF-beta on retinal pigmented epithelium in vitro.
Embryonic chick retinal pigmented epithelium (RPE) has been grown on glass derivatized with covalently bound proteins of basement membrane and treated with transforming growth factor-beta (TGF-beta). In the present paper we show that over the concentration range tested (0.1-10 ng/ml) TGF-beta has no effect on RPE cell proliferation either in the presence or the absence of serum, cell motility and the organization of cytoskeleton-extracellular matrix linkage complexes with respect to their structure and presence of actin, vinculin, talin, integrin and fibronectin. The protein profiles of total cell/ECM extracts of cells grown in the presence or the absence of TGF-beta are similar although some stimulation of protein synthesis and of production of fibronectin-containing extracellular matrix has been detected.
