Abstract

Surface protease activity and secreted protease activity has been determined on several cell lines utilizing 3H-acetyl casein as substrate. When normal rabbit aortic smooth muscle cells and fibroblasts stopped proliferating at high cell density a decrease in surface protease activity was observed. No decrease in surface protease activity or in the rate of cell proliferation was observed in either transformed melanoma or epidermal cells. The decrease of surface protease activity was related to a decrease in cell proliferation.
