视网膜前膜 (epiretinal membranes,ERMs)是细胞在视网膜表面增生的一种表现 ,也是视网膜脱离手术失败的首要因素[1 ,2 ] 。然而 ,对 ERMs形成的发病机制仍不清楚[2 ] 。最近的研究已集中在生长因子对细胞增生的作用上[1 ,3- 6 ] 。生长因子是一类小分子量的多肽类 ,具有直接激 Epiretinal membranes (ERMs) are a manifestation of cell proliferation on the surface of the retina and are also the primary cause of retinal detachment failure [1, 2]. However, the pathogenesis of ERMs remains unclear [2]. Recent research has focused on the role of growth factors in cell proliferation [1,3-6]. Growth factor is a class of small molecular weight peptides, with direct shock
