[Erythropoiesis and osteogenesis (II. The mechanism of the suppression of erythropoiesis during the reparative process in bone tissue)].

The experiment on rats and mice has shown that the presence of a developing callus in the organism after fracture of the tubular bones inhibits erythropoiesis. Inhibition of erythropoiesis is due to delay of erythropoietin biosynthesis by serotonin. A problem on two-fold serotonin effect is under discussion: on the one hand, serotonin inhibits the erythropoietin formation and delays erythropoiesis, on the other hand, it intensifies the effect of ready erythropoietin on the developing bone marrow erythroid cells.
