Overview of Services

Pathology Biorepository Shared Service (PBSS) provides consistent excellence in the collection of high quality banked patient samples while maintaining patient confidentiality.  PBSS also provides pathology, histology, and histotechnology consultation services to assist principal investigators in the procurement, analyses, and clinicopathologic correlation of human tissue specimens.


PBSS was established by the University of Maryland Greenebaum Cancer Center (UMGCC) 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 within the Pathology Department. PBSS is currently 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 high quality tissue samples as well as for pathology and histology expertise.  The frozen tissue archives of PBSS consist of frozen tumor samples and associated paired normal tissue, frozen mononuclear cell isolates, plasma, and serum samples.
