摘要: The retina in most mammals contains two types of macroglial cells--Muller cells, which span the entire thickness retina, and astrocytes, are mainly confined to nerve fibre layer. Whereas Muller cells diffusely distributed all vertebrate retinae, presence distribution retinal astrocytes correlate with blood vessels: retinae that avascular contain no astrocytes; those vascularized a restricted region only region. This striking correlation between vascularization led Stone Dreher postulate immigrants enter its vasculature, although others have suggested they derive from cells. Here we provide strong evidence rat optic nerve.
