[Cellular repair of sublethal radiation damage in 2 subpopulations of the CFUs from embryonal liver and bone marrow of adult mice].

The authors studied the ability of the CFU-s, forming colonies on the 8 and 11 day after transplantation of cells from fetal liver (FL) of 14-18 day gestation and adult mouse bone marrow (BM), to repair the sublethal radiation damages (SRD), according to Elkind's model. The ability to repair the SRD of 11-day CFU-s (both EL- and BM-derived) was lower than the ability of 8-day CFU-s. Both subpopulations of CFU-s (as 8-, as 11-day) from FL have a reduced index of SRD reparation as compared with the corresponding meanings for BM.
