[Conservation of bone marrow CFUc in different phases of the cell cycle during cryopreservation]. / Sokhrannost' kostnomozgovykh KOEc, nakhodiashchikhsia v raznykh fazakh kletochnogo tsikla, pri kriokonservatsii.

The effect of low temperature (-196 degrees C) preservation on the recovery of colon-forming units (CFUs) of bone marrow at different phases of the cell cycle before cryopreservation is dealt with. The intact bone marrow "enriched" with CFUs in S phase of the cell cycle and the bone marrow without colony-forming units in S phase were exposed to cryopreservation. After cryopreservation of the bone marrow enriched with CFUs in S phase and th bone marrow without colony-forming units in S phase the number of CFUs decreases by the same value as in the cryopreserved bone marrow obtained from intact mice.
