PITTSBURGH (KDKA) Injecting stem cells into the brain of someone who has had a stroke is a hot button issue.

Is it safe? Can it be done?

Thats what researchers at the University of Pittsburgh are trying to find out.

Because these are cells that have not been injected into the brain before, we need to know whether it is safe to do so, UPMC neurologist Dr. Lawrence Wechsler said.

So far, at UPMC, two people have received injections of stem cells from the bone marrow of healthy adult donors.

Roger Hill is one of them.

In August 2009, he woke up with a stroke. The first thing he noticed was his vision. He couldnt see half of his world and then his left side left him.

Something happened with my left leg. I fell down, he said. I couldnt feel my left knee.

The problem was in the brain.

A stroke most commonly happens because of a blocked artery. Part of the brain dies from a lack of oxygen and blood flow. Stroke is a leading cause of death and disability.
