[Modeling of the "universal" bone marrow using monoclonal antibodies]

The data on the application of monoclonal antibodies (ICO-10) and rabbit complement for working the conditions of allogeneic bone marrow transplantation are presented in the paper. The treatment with monoclonal antibodies and bone marrow complement from BALB/c mice for 2 times prevented the development of transplant versus host reaction and completely protected lethally irradiated (CBA X X C57B1/6)FI mice-recipients from death. Thymus atrophy and the absence of T-cells in the peripheral blood was observed in these mice. The erythrocytes had markers characteristic of BALB/c and (CBA X C57B1/6)FI mice. Mouse splenocytes did not respond to the cells of donors and recipients in mixed lymphocyte culture reaction.
