Stem cell 'first aid' for stroke

Stem Cells as first aid for strokesStem cells given in the vital period immediately after a stroke may aid recovery, suggest researchers.

Rats injected with stem cells 30 minutes after a stroke had almost normal brain function restored within a fortnight.

The Bolivian research team say the method has potential in human trials.

Current best practice is to treat many patients with "clot-busting" drugs in the "golden hour" after a stroke has taken place.

The research, published in the journal Stem Cell Research and Therapy, adds to others which have found that stem cells could aid stroke patients by boosting the body's ability to repair tissue damage.

Stem cells are the body's "master cells", with the potential to become many different cell types, and theoretically replace cells lost through disease or injury.

Recent tests in humans have show some promise, with stroke symptoms improving after an infusion of stem cells.

The Bolivian team, from La Paz University Hospital, extracted a certain type of stem cells from fat and bone marrow, then injected them into the blood vessels of rats shortly after they had suffered an artificially-induced stroke.

Even though the introduced cells did not appear to travel to the affected region of the brain, the rats still did better than other rats who did not receive the cells.

Within 24 hours, they were already showing a speedier recovery, and two weeks later, they registered almost normal scores on behavioural tests.

Easy to use

The researchers said the early introduction of the cells might even interrupt the typical "chain reaction" of tissue damage which follows a stroke, in which the initial injury harms additional cells in surrounding areas.

Dr Exuperio Diez-Tejedor, who led the research, said: "Improved recovery was seen regardless of origin of the stem cells, which may increase the usefulness of this treatment in human trials."

Dr Clare Walton said: "Stem cells are an incredibly interesting area of stroke research and the results of this study provide further insight into their potential use for stroke recovery."

What you can do today

There are a few ways you can preserve your own stem cells or your children's stem cells but taking advantage of the advances in biobanking and services like cord blood banking or banking stem cells from other rich soiurces like dental pulp.

Similar to stem cells from bone marrow and umbilical cord blood, which have been used for decades to treat leukemia and other blood related diseases, stem cells from teeth have the potential to be used in a broad range of medical applications.
