  • Title: Effects of TGF-beta on retinal pigmented epithelium in vitro.
    Author: Opas M, Dziak E.
    Journal: Exp Cell Biol; 1989; 57(4):206-12. PubMed ID: 2599262.
    Abstract:
    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.
