Pathology Biorepository


Pathology Biorepository Shared Service (PBSS) provides access to a collection of high quality banked patient samples while maintaining patient confidentiality. PBSS provides pathology, histology, and histotechnology services to assist with procurement, analyses, and clinicopathologic correlations of human tissue specimens. Access to a high-quality bank of patient samples permits UMGCCC investigators to perform studies aimed at understanding the biology of normal and diseased tissues with an ultimate goal of translating this knowledge into diagnostic and clinical applications.


Pathology and Biorepository Shared Service was established by UMGCCC in 2006 as a developing core. PBSS has both the unique advantage of the long-standing expertise gained under the well-established relationship with the NCI as well as the advantage of existing expertise and archives of the Pathology Department.

PBSS is the only tissue bank shared service for specimens removed at surgery on the campus.

We have an integrated relationship with the Anatomic Pathology Department, which is essential for obtaining well-characterized tissue samples as well as for pathology and histology expertise.

Frozen tissue archived at PBSS consists of more than 13,000 aliquots of matched tumor and normal tissue from the same patient, and more than 25,000 aliquots of mononuclear cell isolates, plasma and serum.
