[The dual nature of lymphocyte interaction with allogenic stem cells].

The interaction of lymphocytes from mouse lymph nodes with allogeneic stem cells was studied using exogenous colony formation inhibition test. Dual nature of the interaction was revealed: great amounts of lymphocytes inhibited, while small amounts stimulated colony formation. This dependence holds true for macro- and microcolonies as well as for erythrocyte and granuloid microcolonies in the bone marrow during fixation on day 8 and 11 after cell mixture transplantation.
