Background Thromboangiitis obliterans, also known as Buerger's disease, is characterized by peripheral occlusive changes in the arteries of the upper and lower limbs and treatment is often ineffective. Intramuscular transplantation of autologous bone marrow-mononuclear cells (BM-MNC) has been recently reported as improving the symptoms and clinical manifestations in patients with severely ischemic limbs, mostly caused by arteriosclerosis obliterans. The present study focused on the patients with Buerger's disease presenting with rest pain and/or skin ulcer uncontrolled by conventional treatments. Methods and Results Fourteen patients with Buerger's disease (Fontaine III: n=2, Fontaine IV: n=12) underwent transplantation of autologous BM-MNC into ischemic skeletal muscles of either the upper or lower limb. After 4 weeks, rest pain was significantly reduced. In 19 skin ulcers of 9 patients, 8 ulcers were healed and 8 were diminished in the size. These improvements were maintained for 24 weeks without complications. Conclusions In patients with Buerger's disease, intramuscular transplantation of autologous BM-MNC improved symptoms and clinical manifestations, especially skin ulcer.
