In an attempt to repair damage caused by stroke, stem cells were injected in a British man's brain for the first time in the world. The test was made for testing safety of a new therapy meant fro stroke damage.

The safety of a new stem cell therapy for the treatment of ischaemic stroke is the main purpose of this early experimental trial.

The first to receive the therapy in the trial is the stroke survivor and another 11 stroke survivors will be given the treatment if it pass review in a month's time.

For at least two years the patients will be followed. The treatment's effectiveness will be evaluated by the researchers if on function and disability after stroke there is any effect.

For sometime the effectiveness of the stem cell treatment for reversing the damage that is caused by stroke will not be figured out and this is a world first and a newsworthy development.

For disabled stroke patients, being an early stage 1 trial, this is the world's first fully regulated clinical trial of neural stem cell therapy called PISCES or the Pilot Investigation of Stem Cells in Stroke.
