[Number of hematopoietic stem cells in mice in the phase of increased radiation resistance following sublethal irradiation and change in their number after repeated exposure to radiation].

The content of haemopoietic stem cells in mice at the stage of the enhanced radioresistance (day 12 after irradiation with a sublethal dose of 2.75 Gy) was lower than that in the controls. Their repopulation in the repeatedly exposed mice was more intensive than in the intact mice irradiated with the same dose.
