LOUISVILLE, Ky. (AP) - The trio of Sigma Chi fraternity brothers signed up at the University of Louisville for a stem cell donor registry in 2009 and didn't give it a second thought.
But, within a year's time, were told they matched someone as a donor.
Only one in 540 people who register are ever called. Max Voorhies, Matt Venard and Cameron Tillett never expected to get the call.
University of Louisville Blood Transplant program director Dr. Roger Herzig told The Courier-Journal (http://cjky.it/14D0sGo) stem cell donations are vital for patients whose bone marrow has stopped functioning correctly.
Stem cells derived from the blood or bone marrow can form all other types of blood cells, such as the red blood cells that transport oxygen to tissues and the white blood cells that fight infection.
