Researchers at Heinrich-Heine-University in Dusseldorf, Germany, used adult bone marrow stem cells to help quickly regenerate healthy liver tissue, enabling patients to eventually undergo a surgical resection. "Our study suggests that liver stem cells harvested from the patient's own bone marrow can further augment and accelerate the liver's natural capacity to regenerate itself," said Gunther Furst, M.D., co-author and professor of radiology.
