the possibility that these retina-derived endothelial cell growth factors are related to , if not identical with , basic and acidic fgf is supported by observations that they have similar molecular weights ( 15000-16000 ) , similar retention behavior on all steps of chromatography ( ion-exchange , heparin-sepharose ) , and similar amino acid compositions and that they cross-react with antibodies to basic and acidic fgf .
