Northwestern Medicine is the lead site for a study examining stem cell transplantation as treatment for critical limb ischemia. Chief investigator Douglas Losordo, MD, director of the Program in Cardiovascular Regenerative Medicine at Northwestern Memorial Hospital and the Eileen M. Foell Professor of Heart Research of Northwestern University's Feinberg School of Medicine, will present the findings of this study at the American Heart Association's Scientific Sessions in Chicago, on November 17.

"Richard J. Powell MD, chief of vascular surgery at Dartmouth-Hitchcock, is the principal investigator on a national study -- involving 550 patients at 80 sites around the country -- of so-called "no option" patients, for whom the disease is so advanced that amputation is the only available treatment.
Powell's study is now in a three-year, third-stage clinical trial, after second-stage trials showed remarkable success at treating patients with CLI. The final results of the second-stage clinical trial have been published in the April, 2012, issue of Molecular Therapy."

Utterly facinating. Looks like they are getting there then - good job in the doing of!
