| pubmed-article:15896354 | pubmed:abstractText | Microvessels are composed of two types of cells, endothelial cells and pericytes. Pericyte loss or dysfunction participates in various types of disorders, including diabetic retinopathy. Recently, decreased levels of pigment epithelium-derived factor (PEDF) in the eye have been found to predict progression of diabetic retinopathy. However, the effect of PEDF on pericyte growth remains to be unknown. In this study, we investigated whether or how PEDF could stimulate proliferation of cultured retinal pericytes. PEDF stimulated DNA synthesis in pericytes in a dose-dependent manner. PEDF up-regulated pericyte mRNA levels of platelet-derived growth factor-B (PDGF-B). Down-regulation of PDGF-B gene expression by small interfering RNAs completely inhibited the PEDF-induced DNA synthesis in pericytes. Furthermore, PEDF increased protein kinase C (PKC) activity in pericytes and staurosporine, a potent cell-permeable inhibitor of PKC, completely blocked the PDGF-B gene induction and subsequent increase in DNA synthesis in PEDF-exposed pericytes. These results demonstrate that PEDF promotes the growth of cultured pericytes possibly through autocrine production of PDGF-B via PKC activation. Our present study suggests that PEDF could act as a mitogen or survival factor for pericytes, thereby being involved in the maintenance of retinal microvascular homeostasis. | lld:pubmed |
