Stem cells used in stroke trial (UK)

"Doctors in Glasgow have injected stem cells into the brain of a stroke patient in an effort to find a new treatment for the condition. The elderly man is the first person in the world to receive this treatment - the start of a regulated trial at Southern General Hospital. He was given very low doses over the weekend and has since been discharged - and his doctors say he is doing well. Critics object as brain cells from foetuses were used to create the cells. The patient received a very low dose of stem cells in an initial trial to assess the safety of the procedure. Over the next year, up to 12 more patients will be given progressively higher doses - again primarily to assess safety - but doctors will be looking closely to see if the stem cells have begun to repair their brains and if their condition has improved" - BBC
