Bone Marrow
Twonana Campbell, (right) a volunteer, assists Sandra Ely during the bone marrow registration process at the Goldsboro Police Department gym, June 9, 2009. The registration process includes filling out paperwork on health history and swabbing the inside of each cheek. Cheek cells are used to determine a match for a future patient in need of a bone marrow transplant. (U. S. Air Force photo by Airman 1st Class Whitney S. Lambert)
