Abstract
Administration of granulocyte CSF preparation to patients with chronic heart failure produced a hemostimulating effect and increased the content of leukocytes and neutrophils in the peripheral blood. Granulocyte CSF induced mobilization of bone marrow progenitor cells into the peripheral blood. The content of hemopoietic CD34(+)progenitor cells, which attained 0.42% (0.25-0.64) by the end of mobilization, inversely correlated with the number of myocardial infarctions. Administration of granulocyte CSF not only led to mobilization of bone marrow hemopoietic cells, but also increased the pool of endothelial progenitor cells in the peripheral blood: the content of CD34(+)/CD133(+)and CD34(+)/KDR(+)attained 0.02% (0.013-0.075) and 0.1% (0.05-0.20), respectively. Peripheral blood is an available source of progenitor cells, while mononuclear cells after administration of granulocyte CSF can produce a reparative effect on ischemic myocardium.
