Umbilical cord-derived mesenchymal stem cells alleviate liver fibrosis in rats

Figure 1 Mesenchymal stem cells were isolated and purified successfully. A: Mesenchymal stem cells (MSCs) are long spindle-shaped cells (right, magnification × 40); B: Flow cytometry showing that umbilical cord derived MSCs express high levels of CD73, CD105 and CD44, but almost no CD19, CD34, CD45 and CD14; C: The purified MSCs were capable of osteogenesis (left, magnification × 40, by Alizarin Red), chondrogenesis (middle, magnification × 40, by Toluidine Blue O) and adipogenesis (right, magnification × 40, by Oil Red-O).
