Characteristics of mice MSCs (n = 3). a BMSCs transfected with lentiviral vectors were cultured until day 6, The adherent cells reached approximately 80% confluence (×100, scale bar = 100 μm). b Normol BMSCs were cultured until day 6, The adherent cells approximately 100% confluence (×100, scale bar = 100 μm). c The normal BMSCs have better proliferative capacity(*, P < 0.05), Otherwise, The BMSCs transfected with lentiviral vectors can eventually multiply in sufficient numbers. d MSCs were labeled with GFP (×100, scale bar = 100 μm). e FCM revealed that the GFP expression level in BMSCs was approximately 97.21 ± 0.19%. f FCM analysis indicated that the positive rates of MSCs-specific antigens CD29 and CD44 were 97.2 and 97.8%. g The positive rates of CD34 and CD45 were 2.06% and 2.74%
