Hematopoietic stem cells are routinely used as a life-saving procedure in the clinical treatment of hematological malignancies and congenital deficiencies . Hematopoietic stem cells (HSC ) are stem cells prototype useful in clinical practice. In addition to HSC bone marrow are mesenchymal cells , which may differentiate into fibroblast -like cells . Our research shows that enrichment of the bone marrow cells with the phenotype : CD34 - CD45 - CD73 + , CD34 - CD45 - CD90 + , CD34 - CD45 - CD105 + is related to the number of CFU -F.
