Whole bone marrow transplantation induces angiogenesis following acute ischemia.

Several recent studies have shown that purified subsets of bone marrow (BM) cells can differentiate into endothelial, cardiac, and other cell types. During coronary artery bypass graft (CABG) surgery, sternal BM is routinely discarded. To determine if this BM can be used to induce angiogenesis and augment perfusion of the cardiac tissues after CABG, a simplified and more practical approach of using whole BM extract was tried to determine whether it would be adequate for the induction of BM-derived angiogenesis in experimental acute limb ischemia.
