CYTOSTATIC ACTION OF HUMAN FIBROBLAST INTERFERON IN DIRECT GROWTH INHIBITION: EFFECT ON HUMAN MALIGNANT MELANOMA

The mode of action of the direct antiproliferative effect of human fibroblast interferon (HuIFN-β) on tumor cells was analyzed in vitro with a human malignant melanoma cell line, HMV-1. HuIFN-β inhibited the growth of HMV-1 cells in a time-dependent fashion (50%-inhibition concentration:
