Transfection efficiency of miR-26a in CD34+ stem cells and cell viability. a Morphology of CD34+ stem cells shown by light microscopy. Scale bar: 200 μm. b Surface markers of CD34+ stem cells measured by flow cytometry. c CD34+ stem cells transfected with miR-26a successfully observed under a fluorescence microscope. Scale bar: 200 μm. d miR-26a was overexpressed in CD34+ stem cells compared with the non-infected cells. e CD34+ stem cell viability showed no significant differences between the non-infected CD34+ stem cells and the CD34+ stem cells infected with miR-26a. **P < 0.01
