LONDON (Reuters) - British researchers have identified the cancer stem cells that spawn tumors in the most common form of childhood leukemia, and said on Thursday it provided a “bull’s eye” target for new drugs. These rare stem cells are a minute component of the blood but self-renew and act like a control centre, producing millions of cancerous leukemia cells that overwhelm the normal system, said Tariq Enver, a researcher at the University of Oxford, who worked on the study.
