RESUMO

Experiments made in vivo and vitro have demonstrated that conservation of allogeneic hemopoietic tissue with glycerin brings about a decrease in transplatation, homologous activity of T lymphocytes. Allogeneic bone marrow conserved with glycerin compares very favourably with freshly prepared allogeneic bone marrow since the transplant-versus-host reaction is attenuated under the effect of glycerin. Moreover, it shows a higher proliferative activity. The glycerin-induced reduction of the inactivating effect of lymphocytes against non-syngeneic colony-forming units enables the conserved bone marrow to be transplanted from several donors.

RESUMO

A method has been developed of decreasing immunologic activity of lymphocytes from spleen, lymph nodes, and bone marrow (freshly collected or frozen) with a high percentage of intact stem cells. In experiments in vivo on lethally irradiated mice, it was demonstrated that during combined transplantation to the recipients of preserved bone marrow from two genetically different donors, a rapid decrease or absence of the effect of inactivation of hemopoietic stem cells under the influence of allogeneic lymphocytes was observed in the mixed graft. When it is necessary to transplant large quantities of bone marrow from several genetically different donors, the use of cryopreserved bone marrow is preferable to freshly drawn marrow due to the higher proliferative activity and the decreased risk in the development of immunological reactions.
