Osteogenic differentiation potential of umbilical cord-derived mesenchymal stromal cells (UC-MSCs) in comparison to bone marrow-derived mesenchymal stromal cells (BM-MSCs). (A) The negative result for Alizarin Red staining of BM-MSCs cultured in DMEM supplemented with 10% fetal bovine serum (FBS) for 21 days. (B) The positive result for Alizarin Red staining of BM-MSCs cultured in osteogenic differentiation medium for 21 days. (C) The negative result for Alizarin Red staining of UC-MSCs cultured in DMEM supplemented with 10% FBS for 28 days. (D) The positive result for Alizarin Red staining of UC-MSCs cultured in osteogenic differentiation medium for 28 days. Scale bar, 100 µm.
