Furthermore, immunohistochemical analysis for human CD105, human CD34, proliferating cell nuclear antigen (PCNA), single strand DNA (ssDNA), caspase 3, aquaporin (AQP)1, α-smooth muscle actin (α-SMA) and mouse CD34 were performed.  Furthermore, immunohistochemical staining revealed a significant decrement in the number of ssDNA positive apoptotic cells, but a significant increment of PCNA positive proliferating cells, AQP1 positive blood capillaries, α-SMA positive myoepithelial cells and endogenous CD34 positive hematopoietic progenitor cells in the OVX+hUCB-MSCs group as compared with the OVX group.
