PURPOSE Platelet-derived growth factor (PDGF) and its receptors could contribute to the development of proliferative retinal membranes, because PDGF is angiogenic and is both mitogenic and chemotactic for retinal pigment epithelial (RPE) and glial cells, components of membranes. The authors sought to determine whether PDGF ligands and their receptors were(More)
PURPOSE Integrins are cell surface proteins that participate in interactions between cells and with extracellular matrix. Binding of integrins to their ligands influences cell activities including proliferation, migration, and differentiation. Expression of integrin subunits from three different subfamilies were examined in human retina. METHODS Integrins(More)
Immature and adult rat eyes were bisected and incubated with 35-SO4 and 3-U-galactose in short-term pulse-chase experiments. Autoradiographs (ARG) of the tissue revealed that very little sulfate is incorporated by the peripheral neural retina, the pigment epithelia of the retina, ciliary body, or iris. The inner, inverted optic cup cells at the ora serrata,(More)
OBJECTIVE To demonstrate the progression of electroretinographic (ERG) findings in mucolipidosis IV. METHODS Two patients with mucolipidosis IV were examined clinically and their condition was followed up for ophthalmic manifestations of the disease. Electroretinograms were performed on both patients, and conjunctival biopsy specimens were analyzed for(More)
