Blood serum leukopoietic activity after the injection to intact Wistar rats of products of 12 and 60 million homologous granulocytes lysis per 100 g of animal body weight, and the character of the serum action on the proliferation and differentiation of stem hematopoietic cells in the spleen of lethally irradiated mice were studied. Accumulation in the blood of granulocytopoietins resulting from the action of the products of granulocytes lysis was noted. Granulocytopoietins stimulated the proliferating activity of stem cells and their differentiation into granulocytes in the spleen of the lethally irradiated mice. A conclusion was drawn on the stimulating action of granulocyte lysis products on the hemopoiesis through the granulocytopoietins.
