Confocal images of brain sections from rats after MSCs transplantation.: (A)4 days in group SVV, (B)4 days in group GFP, (C)14 days in group SVV, (D)14 days in group GFP, (Column1) GFP-positive cells (write arrows), (Column2) neuronal marker NeuN-positive cells(green arrows). (Column3) GFP-positive MSCs (yellow arrows) expressed neuronal marker NeuN. (E) Quantitative analysis of the number of survival MSCs at 4 and 14 days after transplantation. Data are mean ± S.D. (n = 6), Scale bar = 100 um. *P < 0.05, #P < 0.01.
