title: [Hybrid resistance to precursor cells of bone marrow stroma].
abstract: A focusl of hemopoiesis appearing after the transplantation of a bone marrow fragment of C57BL mice to syngeneic mice (under the kidney capsule) contained more hemopoietic cells than in transplantation to the semisyngeneic (CBA X C57BL) FI recipient. Experiments were conducted with a secondary seeding by intravenous injection of hemopoietic cells of the C57BL transplant genotype into the transplant depopulated by irradiation; it was shown that these differences were caused by lesser dimensions of the hemopoietic microenvironment in the focus in the hybrid organism in comparison with such in the syngeneic system. Thus, the hybrid resistance was expressed not only to the hemopoietic cells, but also to the stromal precursors transferring the hemopoietic microenvironment.
