Abstract
An inhibitor of endothelial cell growth is prepared by directly liquifying vitreous gel, as for example, forcing vitreous gel through a small orifice so as to directly convert the gel into a liquid, removing insoluble and suspended material and chromatographically fractionating the liquid and isolating the fractions. An inhibitor is also prepared by culturing hyalocyte cells in a medium and chromatographically fractionating the medium.
