title: Cytotoxic and mitogenic activities in culture media conditioned by mouse B16 melanoma cells and 3T3 fibroblasts.
abstract: Cytotoxic and mitogenic soluble factors are released into media conditioned by pure or mixed populations of mouse 3T3 fibroblasts and B16 melanoma cells cultivated in vitro. These activities are demonstrated by the use of MTT cell survival test and 3HTDR incorporation. Mitogenic (M.W. greater than 10,000) and cytotoxic factors (M.W. less than 1,000) are present and are generally more active on B16 cells than on fibroblasts. Their release into conditioned media is related to the rate of pigmentation in B16 cells and to the mode of cultivation (monolayers or cell aggregates).
