title: [Kinetics of the basic sections of the hemopoietic system in radiation chimeras].
abstract: During first 3 days after mice irradiation and syngeneic bone marrow transplantation in them the number of CFUs (about 0,5% of the injected cells) was stable, although the proliferation induction began 24 hours after transplantation. As it was shown by the method of "thymidine self-distruction". Twenty four hours later all the CFUs entered the mitotic cycle. On the contrary, the commited cells (granulopoesis precursors) compartment (CFUc) enters the logarithmic growth phase since the first day. The exponential growth of the CFUs number was observed from the 4th day simultaneously with the increasing of the proliferation rate of CFUc and the beginning of the recovery of the bone marrow cells total number. In late radiation chimeras (1 month after radiation and reconstitution) the total number of CFUs was 50--70% of the initial. The other hemopoetic parameters were in the normal limits.
