Access Biospecimens & Data

U-M researchers are encouraged to explore with the DataDirect cohort-discovery tool to identify available Michigan Medicine biospecimens stored at the CBR.  Researchers interested in further investigating the availability of CBR specimens resulting from their DataDirect query should complete and submit a CBR Use Proposal Form and send to



In addition to these biospecimens, the CBR collaborates with other programs at University of Michigan to provide human samples for research. 

Tissue Microarrays and detailed clinical information from patients with breast cancer, is available from the Breast Oncology Program.  Contact Dr. Dafydd Thomas for more information.

Biospecimens from patients with Chronic Kidney Disease (CKD) can be requested through two different CKD biorepositiory programs.  Please visit the Nephrotic Syndrome Study Network or the George M. O'Brien Michigan Kidney Translational Core Center to find out more about these important resources.

Access requests are subject to the approval of the program-specific Oversight Committee, as well as the appropriate regulations and IRB approvals. Decisions made on Use Proposals by Oversight Committees may be appealed to the CBR Governance Committee. Whenever possible, the CBR and the Data Office deliver a final coded dataset without any direct identifiers.
