Research Abstract |
Therapeutic angiogenesis induced by the implantation of autologous bone marrow-derived cells has been iced for the treatment of ischemic diseases. However, clinical trials have shown obvious individual differences in the improvement of regional perfusion after the implantation of autologous bone marrow cells. In this study, we aimed to identify the risk factors related to the functional impairment of bone marrow cells for inducing therapeutic angiogenesis. We collected clinical and laboratory data from 25 patients scheduled to undergo sternotomy for various surgical procedures. Then, we aspirated bone marrow cells from the sternum during the operation, and investigated their angiogenic potency in vitro by cultivation, and in vivo using an ischemic limb model in SCID mice. We identified that aging, renal failure, anemia, and high serum levels of triglyceride, CRP, IL-6, and NTX (the markers of bone metabolism) were significantly correlated with poor angiogenic potency of bone marrow cells. We assigned scores to these risk factors according to their Pvalue, and found a strung correlation between the risk scores of patients and the angiogenic potency of their bone marrow cells (r=0.778, P<0.001). In elusion, we identified the risk factors related to poor angiogenic potency of bone marrow cells. Our results provide important information to help us select patients who will benefit most from this treatment in future clinical trials.
