HUMAN FIBROBLAST GLYCOPROTEIN, CELL DIFFERENTIATION, BLOOD VESSEL ENDOTHELIAL CELL GROWTH FACTOR, CELLULAR IMMUNOLOGY INFORCING FACTOR OF 78 OR 74 THOUSAND DALTONS PLUS OR MINUS TWO THOUSAND DALTONS

摘要

A glycoprotein is obtained from a supernatant of a culture medium of the fibroblasts of human origin. It has an antitumor activity and activities of inducing the differentiation of leukemia cells, enhancing cell-mediated immunity, accelerating the proliferation of endothelial cells of human blood vessel, and proliferating hepatic parenchymal cells.
