| Research Abstract |
In the present study, we first assessed a process of collateral augmentation in the rabbit model of limb ischemia. After an excision of the left femoral artery, main route of collateral vessels was developed between the left inferior gluteal artery and the left popliteal artery, which was located in the left coccygeo-femoral muscle. Based on the findings, we selectively administrated basic fibroblast growth factor (bFGF) or bone marrow mononuclear cells (MN) to the left coccygeo-femoral muscle or the left adductor muscle at 28 days after femoral artery removal. At 28 days after administration of bFGF or MN, limb ischemia after the delivery to the coccygeo-femoral muscle were significantly improved as compared with those to the adductor muscle, suggesting that selection of delivery target was an important factor to promote effective collateral augmentation.
