Fig. 2. (A) Confocal images of GFAP (green) and human nuclei (HuNu) staining (red) with a DAPI nuclear marker (blue) in ischemic rats with and without hUCB-MSC treatment. GFAP- and HuNu-positive cells were detected in the ischemic boundary zone. GFAP- and HuNu-positive cells were increased in number compared to the control group. (B) The number of GFAP-positive cells was increased in the hUCB-MSC-treated groups compared to the control group. Scale bar=50 µm.
