Human Tissues and Organs for Research Resource Program funded by the National Institutes of Health 

“Were it not for the availability of precious tissues supplied by NDRI, this field of biomedical and bioscience research would not be where it is right now.”

- Francis S. Collins, MD, PhD, Director, National Institutes of Health,

NDRI’s Human Tissue and Organs for Research Resource (HTORR) Program has been funded by the National Institutes of Health (NIH) for over 30 consecutive years to support research programs across multiple disciplines. It is through the HTORR program that NDRI provides biomedical investigators with donated normal and diseased human tissues and organs recovered from a diverse donor pool using customized procurement, processing, and preservation and distribution protocols.

In August 2018, the NIH awarded NDRI with a five-year $6.5 million grant for the recovery of human tissues and organs for research. The HTORR award was followed by an additional $800,000, a series of supplemental grants providing support for NDRI to serve as a human biospecimen resource for research focused specifically on Alzheimer’s disease, Autism Spectrum Disorder (ASD) and HIV/AIDS.
