Endothelial cell-stimulating angiogenesis factor in vitreous from extraretinal neovascularizations.

摘要: The presence of endothelial cell-stimulating angiogenic factor (ESAF) in diseased human vitreous humour has been established. molecular mass and chromatographic behavior this material its property activating procollagenase indicate it to be identical the ESAF isolated from other sources. biological activity was demonstrated by ability induce positive responses rabbit corneal pocket, chick chorioallantoic membrane yolk sac tests.
