title: [The effect of serotonin on the hematopoietic stem cells of the bone marrow].
abstract: Haemopoietic stem cells content and proliferative activity were studied in the bone marrow of female F1 (CBA x C57Bl6) mice after single (50 mg/kg) and chronic (0.5 mg/kg daily for 7 days) serotonin (S) injections. It is shown that 9-day and 12-day COEs contents in the bone marrow of experimental mice has been increasing for 24 h after single S injection. After chronic S injections twofold increase of 12-day COEs is observed without any increasing of 9-day COEs. Total myelokaryocyte number is increased too. The study of proliferative status by in vitro incubation of bone marrow cells with ARA-C has shown that the numbers of 9-day and 12-day COEs in S-phase have increased both after single and chronic S injections. Possible mechanisms of stimulating effect of S on bone marrow stem cells are discussed.
