title: Expression of c-fms proto-oncogene product by ovarian cancer cell lines with effects of macrophage colony-stimulating factor on proliferation.
abstract: We studied the production of macrophage colony-stimulating factor (M-CSF) and the expression of c-fms mRNA, an M-CSF receptor, in four human ovarian cancer cell lines. All four cell lines expressed c-fms mRNA while three secreted M-CSF into the culture medium. The exogenous administration of M-CSF caused no significant enhancement of cellular proliferation in any cell line. Interestingly, the proliferation of KK cells was not affected by anti-M-CSF antibody. These results, taken together with the fact that ovarian cancer cells simultaneously produce M-CSF and c-fms, suggest that an autocrine mechanism may modulate cellular proliferation.
