NCT00001627

Brief Summary

This study is designed to provide bone marrow and/or blood cells for other research studies. Patients participating in this study will be asked to provide small amounts of medical information and undergo a limited physical examination designed to detect the presence of any obvious blood disease. A blood and bone marrow sample will be obtained to verify that the patient has normal blood cell production. Researchers plan to obtain bone marrow samples to be used in laboratory studies directed toward understanding the formation of blood cells. Bone marrow samples will be taken from the hip bone of patients and healthy volunteers. These samples are valuable to many research studies within the Hematology Branch of the National Heart, Lung, and Blood Institute, including studies of normal and abnormal production of blood cells, the viral causes of blood diseases, and the role of the immune system in bone marrow failure and related conditions....
