Using mouse model of regeneration of critical size cranial defects, we studied combined effect of 1 and 10 μg of BMP-2 of prokaryotic origin and recombinant erythropoietin (Epostim) injected subcutaneously in the area of bone defect in a total dose of 6000 U/kg. Erythropoietin considerably improved quantitative and qualitative characteristics of the bone tissue in the site of implantation when used in combination with BMP-2 in both concentrations.
