We expect the great majority of publications from the Center for Human Immunology, Autoimmunity, and Inflammatory Diseases (CHI) over the next several decades will be generated from exploratory laboratory research studies done using blood and bone marrow and other tissue samples from such patients and their family members. These publications are expected to number in the hundreds. Ongoing and future research projects depend on the ready availability of samples of blood, tissue, leukapheresed cells, and bone marrow from patients for in vitro studies.
