Resumo
The effects of heterotransplantation on bone marrow structures were studied in experimental male mice. Suspension of the bone marrow from feline femur (1 ml bone marrow diluted in isotonic saline, 1:2) was injected into the caudal vein. Heterotransplantation led to an increase in the level of serotonin involved in cell differentiation. In 2 days, the counts of all cells except erythroid cells decreased. Immunohistochemical analysis of Ki-67 marker within 40 min after transplantation showed a significant increase of cell proliferative activity in comparison with that in intact mice. At later terms, the expression of Ki-67 in bone marrow cells decreased, while the expression of apoptosis regulator P-53 increased, which was associated with the presence of numerous dead cells.
