SummaryThe growth of thiol dependent cells of Lymphoma L1210(V) is supported by 3T3 and L cells as well as by macrophages in vitro. The supporting cells do not permanently condition the medium, but diffusion chamber studies show that growth promotion is mediated humorally. At high cell density inhibition of lymphoma cell growth can be observed in the supernatant from one of the 3T3 sublines examined, which appears to be due to a nondialyzable inhibitor whose effect is unrelated to thiol dependency.
