Figure 5: On the 8th week after transplantation, the injected sites and needle passage was showed by hemosiderin staining (the specific place was indicated by the red arrow, Scale bar=50 μm) (A). More lymphocytic infiltration and glial cell proliferation were found around the needle passage for the PBS injected group (B) than in the AMSCs transplanted group (C), (HE staining, Scale bar=100 μm). (D) Under the fluorescence microscopy, the Brdu positive AMSCs were found distributed around the needle passages (Scale bar=200 μm).
