Retinal glia migrate to sites in the vitreous body and on the inner and outer surfaces of the retina during a wide variety of pathological processes. Using in vitro cultures of rat retinal glia, we have evaluated an extensive list of homogeneous, well-characterized growth factors as chemoattractants for these cells. Humoral growth factors, fibroblast growth factors, extracellular matrix proteins and immune system cytokines all were without activity except for the platelet-derived growth factor (PDGF). Extracts of bovine ocular tissues including vitreous body and retina yielded significant activity.
