Dr Sharlin Ahmed, Research Liaison Officer at The Stroke Association says:

"When a stroke strikes the brain is starved of oxygen and as a result brain cells in the affected area die. The use of stem cells to replace dead brain tissue is a promising technique which could help to reverse some of the disabling effects of stroke.

"We are very excited about this trial; however, we are currently at the beginning of a very long road and significant further development is needed before stem cell therapy can be regarded as a possible treatment."
