Beike Biotechnology recently performed a study on sufferers of peripheral artery disease, transplanting peripheral blood stem cells into the lower extremities of the patient. After 12 weeks of the study, an overwhelming majority of PAOD reported improvement in pain and coldness, including the healing of ulcers and an improvement in limb gangrene.
At the same time, a research team in Chicago has found a way to reduce angina symptoms in "non-option" patients (those unable to undergo surgical angioplasty) by implanting adult stem cells directly into the heart.
Are we seeing a shift away from the more controversial method of embryonic stem cells and towards the promising--and more scientifically sound--future of umbilical/adult stem cells?
