Researchers have long considered the NCI supported Cooperative Human Tissue Network (CHTN) as a source for quality collection and preservation of tissue samples from remnant surgical tissue specimens. In an organized tissue procurement setting serving a large population of researchers, the trained procurement personnel, specialized reagents and monitored frozen storage facilities assure the availability of quality research, monitored preservation techniques and temperature controlled shipping required for successful research support.

The CHTN Midwestern Division (MWD) has experienced an increase in investigator demand for fresh tissues over the past two years. Approximately 23% of the tissues distributed by the CHTN MWD is fresh tissue. Requests for frozen and formalin-fixed paraffin embedded tissues, however, remain constant and stable. The increased interest in fresh tissue likely reflects an increased focus on the study of vital cells in…
