Tissue Resources

The Tissue Resources Core facility is a specialized unit of the Human Tissue Procurement Facility (HTPF) that supports Cancer Center member researchers by acquiring, preserving, and distributing high quality human tissues and providing priority histology, immunohistochemistry, tissue microarray, and laser capture microdissection services for both human and animal tissues. Services are open to all Cancer Center members on an equal basis. Free parking is provided to members picking up samples who work off the CWRU/University Hospitals campus.

Samples are for research purposes only and may not be used for clinical diagnosis or implantation into humans. Clinical information relating to the samples and donors are collected and maintained in a secure database. Samples and data are de-identified or de-linked before release to the researcher unless he/she has specific IRB approval to gain access to this information. 

Please note: Researchers must complete a formal application and have an IRB approval or exemption for the study to access human tissue from the Core.
