Collection of Bone Marrow Aspirate From Volunteer Donors

This study is designed to provide bone marrow cells for other research studies. The research is being done because there are ongoing experiments in a number of National Institute on Aging (NIA) laboratories that require access to normal human bone marrow aspirate for their studies of the immune system. These studies are done to understand how blood cells are formed and how they function. Samples will be used to study problems such as the immune system in bone marrow failure and related conditions. Cells will be used in laboratory research and may be banked for future laboratory studies
