An internationally known specialist in the field of adult stem cell biology, his 2005 discovery of embryonic-like stem cells in adult bone marrow has potential to revolutionize the field of regenerative medicine. The discovery may lead to new treatments for heart disease, eye disease, diabetes and neurodegenerative disorders, as well as provide insight into the development of many forms of leukemia.
