Abstract (original English)
In recent years, identification of new sources of adult stem cells developed rapidly, pursuing to find easily available tissues, which will give rise to homogenous stem cells populations. Up to present, bone marrow-derived mesenchymal stem cells (BM-MSCs) are unanimously considered to fulfill the criteria for being used in clinical settings, but adipose stem cells, placental and umbilical cord stem cells, and other tissue-derived stem cells are making their way to being used at least in autologous transplantation. We isolated cellular populations from placental tissue and umbilical cord using the explants method. The placental (PL) and umbilical cord (UC)-derived cells were cultured and expanded in appropriate conditions for generation of stem cells. We assessed the stemness characteristics of the tissue-isolated cells and compared them to an established MSCs line. For this purpose, we determined the immunophenotype, morphological and ultrastructural characteristics, as well as functional abilities of PL- and UC-derived cells. Flow cytometric evaluation of cells revealed presence of CD90, CD73, and CD105 stem cells markers, while the cells were negative for CD34, CD45 and HLA-DR. Immunocytochemical staining showed that 100% of PL- and UC-derived cells are positive for vimentin and CD105 expression, while cytokeratin was revealed in less than 10% in both tissue-isolated cells.
