Membrane association of collagenase stimulatory factor(s) from B-16 melanoma cells.

Abstract

Past studies have shown that contact between tumor cells and fibroblasts results in stimulation of collagenase production by the fibroblasts. Membrane fractions prepared by differential centrifugation of sonicated B-16 melanoma cells were shown here to contain a collagenase stimulatory factor(s) (CSF). Trypsin treatment of intact B-16 cells prior to… (More)
