According to The Guardian
Stroke patients who took part in a small pilot study of a stem cell therapy have shown tentative signs of recovery six months after receiving the treatment.
Doctors said the condition of all five patients had improved after the therapy, but that larger trials were needed to confirm whether the stem cells played any part in their progress. Scans of the patients’ brains found that damage caused by the stroke had reduced over time, but similar improvements are often seen in stroke patients as part of the normal recovery process.
