[Effect of age of mouse recipients on the functional activity of transplanted hematopoietic and lymphoid cells].
When transplanting the bone marrow cells from adult C57BL mice to the lethally irradiated (CBA X C57BL) F1 hybrids of different age, the decrease of the colony forming activity of the stem haemopoietic cells was observed in the spleen of the older recipients, as compared with the 3 months old ones. The joint transplantation of the bone marrow and thymus cells resulted in both the cases in the stimulation of the growth of colonies. The number of endogenous colonies of haemopoietic cells arising in the spleen of animals following the sublethal irradiation was greater in younger hybrids. After the induction of the "transplant versus host" reaction by the lymph node or spleen cells from the CBA mice, the relative weight of spleen and regional lymph node, respectively, in the older recipients exceeded those in the younger ones.
