FIELD: biotechnologies.
SUBSTANCE: method is proposed to extract stem cells, including whirling of heparinised bone marrow with hydroxyethyl starch at the ratio of source ingredients of 1:2 with speed of 700g for 15 min. in the closed system of three haematological containers connected to each other with tubes with subsequent removal of fat admixtures and plasma into the container No.1, transfer of the mononuclear fraction of bone marrow, a part of supernatant and erythrocytes adjoining the interface of two media into the container No.2. Sludged erythrocytes and bone fragments remain in the main container, whirling of the produced sample with the speed of 900g for 15 min. in the container No.2 to produce cell material for intravascular introduction, at the same time after the specified whirling a part of supernatant is removed into the container No.1 without unsealing of the system.
EFFECT: production of paracrine effect of bone marrow mononuclear cells and provision of safety.
