Collection and Analysis of Blood, Bone Marrow, and Buccal Mucosa Samples From Healthy Volunteers

Recruiting
Conditions
Healthy Volunteers
Registration Number
NCT00442195
Lead Sponsor
National Heart, Lung, and Blood Institute (NHLBI)
Brief Summary

The Hematology Branch of the National Heart, Lung, and Blood Institute is doing a variety of laboratory research experiments that require blood and tissue samples from healthy volunteers. This protocol provides a mechanism for collecting these tissue samples. Research includes studies of normal and abnormal formation of blood cells, viral blood diseases, the role of the immune system in marrow failure and genetic risk factors for aplastic anemia.

Healthy normal volunteers 8 years of age and older may be eligible for this study. Samples are collected as follows:

* Blood samples: Participants 8 years of age and older donate up to 4 tablespoons of blood, which is obtained from a needle placed in an arm vein.

* Participants 8 years of age and older donate a buccal mucosa sample (cells from the inside of the cheek). The inside of the cheek is scraped gently with a nylon brush.

* Participants 18 years of age and older donate a bone marrow sample. The bone marrow is obtained from the hip bone. The skin over the area is wiped clean with alcohol and iodine, and then a local anesthetic is injected under the skin and also into the bone. When the area is numb, a bone marrow aspiration needle is introduced through the bone surface into the marrow. The marrow cells are collected using a syringe connected to the needle.

Detailed Description

The purpose of this protocol is to collect and analyze blood (ages 8 and older), bone marrow (ages 18 and older), skin tissue samples (ages 18 and older), and/or buccal mucosa samples (ages 8 and older) from healthy volunteers. Samples will be used for clinical and translational research in the NHLBI and are indispensable for many of our research projects, including studies of normal and abnormal hematopoiesis, the viral etiology of blood diseases, the role of the immune system in marrow failure and genetic risk factors for aplastic anemia. This protocol provides a mechanism for collection, tracking, storing, dispensing, analyzing and disposing of these laboratory research samples.
