Stem cell therapy could help the recovery of stroke victims, according to a small study from Imperial College London.1
The study only examined a group of five people, but it showed positive results to using the patient's own stem cells after an ischaemic stroke (a type of stroke where a clot forms and reduces or blocks blood flow). While the results were positive, the study was not designed to check how effective the treatment was. Instead, it was designed to test if the treatment is safe, and it would appear that this is the case.
While we cannot be sure that the improvements wouldn't have happened without the stem cell treatment, it does mean that a much larger trial is now likely.
