Aim ― To reveal the results of the condition of the bone marrow mononuclear cells (BM-MNCs) with erythropoietin (Epo). Material and Methods ― There were 30-ty patients with coronary artery disease (CAD) enrolled in this study during 2016-2017 years. 95% were men. All were in angina NYHA class II-III. Hypertension presented in 90%, peripheral atherosclerosis in 60%. BM-MNCs were obtained by centrifugation of bone marrow aspirate on Ficoll-Paque, washed, and then preconditioned with Epo. Phenotype, cell cycle, cell death, proliferation, migration, and tube formation before, and after precondition BM-MNCs with Epo were done. Results ― In this study, we observed the presence in cellular graft of the hematopoietic stem cells (HSCs), and endothelial progenitor cells (EPCs) at the different stage of maturation/differentiation, and mesenchymal stem cells (MSCs). Precondition BM-MNCs with Epo increased number of HSCs carrying erythropoietin receptor (EpoR), and EPCs carrying CD184. Also, Epo detained СВ34+ cells in a rest phase of cell cycle (G0G1). Condition media from BM-MNCs treated with Epo augment tube formation and wound healing by EA.hy 929. Conclusion ― Epo in vitro increased number of the stem cells carrying EpoR and CD184, and increased accumulation of CD34+ cell in G0G1 phase of cell cycle, and induced production of proangiogenic factor by BM-MNCs. Further investigation is needed to assess the type of cytokines produced by BM-MNCs after condition with Epo.
