Biorepository Core

Alexander Stokes, Ph.D., Core Director

The ability to move research into human tissues increases the direct human relevance and applicability of that research. As one “arm” of the University of Hawaii Biorepository, the BRIDGES-funded Comprehensive Human Organ and Tissue Bank (CHOTB) core facility is the only fully inclusive human tissue biorepository in the State of Hawaii. We provide a wide range of fresh-frozen human tissues or subcellular tissue fractions. The tissue and extracts in the Core are derived from our unique population of Hawaiian/part Hawaiian, Pacific Islander, Japanese, Chinese, Filipino, Korean, Vietnamese, Hispanic, Caucasian and African Americans. This core is therefore uniquely placed to serve minority populations and to address health disparities, as we are able to collect comparatively large numbers of samples from minority donors that will allow for appropriate powering of studies in minority health.

Associated with Hawaii’s Legacy of Life organ donation team, the CHOTB receives organs that are unfortunately not placed for transplant. The donor’s families consent to provide the organs for research, and the donor’s deidentified clinical information is uploaded into our database. The CHOTB is a growing resource currently housing 31 livers, 27 hearts, and 8 kidneys from 4 donors. Several of our samples are matched with spleen wedges, blood, and/or lymph nodes. The bulk of these samples are “normal” non-diseased tissues allowing for cohorting with diseased specimens and/or studying disease processes without underlying complications.

The CHOTB provides restricted access to human tissues and clinical information for research purposes. Please visit the University of Hawaii Biorepository website (link below) as your portal for more information about the CHTOB, including the list of available samples and complete details on how to apply for access:
