A : The injection of BMSCs into the temporal muscle increase angiogenesis. Chronic cerebral ischemia is induced by bilateral common carotid artery ligation, and BMSCs are injected into the temporal muscle 7 days after the induction. The capillary/muscle ratio is increased in the BMSCs transplantation group compared to the control group (p=0.011). B and C : Photomicroscopic examination findings of the temporal muscles stained with India ink and DAPI also shows increased angiogenesis in the BMSC transplantation group. (B) The temporal muscle of the BMSCs transplantation group shows a more prominent capillary/muscle ratio than the (C) control group. The nuclear DNA is stained with DAPI (blue dot), and the capillary is stained with India ink (black dot)(Magnification ×200). DAPI : diamino-2-phenylindole 2 HCL, BMSCs : bone marrow stromal cells.
