Bone marrow and peripheral blood T cells were obtained from 15 normal individuals by E rosetting and cultured in round-bottomed microwells for 7 days in RPMI or in RPMI supplemented with mitogens (pokeweed mitogen, phytohemagglutinin or concanavalin A). Supernatants and cells were harvested on days 1, 2, 3, 4 and 7 and co-cultured with normal marrow cells in semi-solid agar to test their CFU-c suppressor activity. The results of this study indicate that (a) RPMI treated cells and their supernatants have no effect or an enhancing effect on CFU-c growth; (b) all 3 mitogens generate CFU-c suppressor T cells on day 1 of culture; (c) the inhibitory activity is detectable until day 4 of culture, though overall reduced, and is completely lost on day; 7 (d) the trend for supernatants of mitogen-treated T cells is quite similar with a tendency to complete loss of the inhibitory effect on day 7. We interpret these data as indicating that T cells release a soluble inhibitor of CFU-c growth within a few hours from polyclonal activation, the production of which is either controlled or lost with time in culture.
