Platelet-derived growth factor ligands and receptors immunolocalized in proliferative retinal diseases.

Abstract

PDGF ligands and receptors are widespread in proliferative retinal membranes of different origin. Because PDGFR beta and PDGF-B were colocalized in many of the same cells, the potential for autocrine and paracrine stimulation of cell migration and growth exists. These results are consistent with a role for PDGF ligands and receptors in the pathogenesis of different proliferative retinopathies.
