Tracking of transplanted PKH26 labeled BM-MSCs in the aortic walls. A) Representative aortic sections from group CONT. B) Representative aortic sections from group MSC4. Four weeks after operation, PKH26-positive BM-MSCs were mainly observed in the adventitia of aorta in group MSC4. Arrows point to sites of BM-MSC. At least three random aortic cross sections per mouse were chosen for evaluation. PKH26 (red), DAPI (blue), Scale bars = 100 μm.
