| Outline of Final Research Achievements |
Treatment of critical limb ischemia is sometimes difficult due to the patient’s condition. The hindlimbs of Sprague-Dawley rats, after 20 Gy X-ray radiation and surgical occlusion, were divided with superficial fascial flap, 5.0 × 106 adipose-derived stromal/stem cell (ASC) and both combined. There were no significant differences between the flap alone and ASC alone treatment groups. Wound healing was significantly increased in the combined treatment at 1 week and there was no wound by 2 weeks except for the no flap and no ASCs group. Von Willbrand factor, blood vessel, showed a significant increase in the combined treatment group, both at 1 week and 2 weeks. In the cell tracking, at 2 weeks, the GFP-tagged ASCs were significantly more positive in the no flap group than in the flap group. ASCs may be a potent cell source in radiated and occluded limbs by enhancing tissue blood flow and blood vessel density.
