MSCs with fluorescence after transfection with lentiviral vectors and efficiency of miR-1 transfection. (a) Visible light field; (b)  green fluorescence field (Original magnification × 200 in (a) and (b)); (c) the efficiency of miR-1 transfection was analyzed by qRT-PCR, evident miR-1 expressed in MSCs^miR-1, barely expressed in MSCs^null and control group (control = MSCs; MSCs^null = MSCs infected with mock lentiviral vectors without miR-1; MSCs^miR-1 = MSCs infected with miR-1 recombinant lentiviral vectors; compared to control group, *P < 0.01; compared to MSCs^null, ^# P < 0.01).
