HTORR Program

Human Tissues and Organs for Research Resource Program funded by the NIH

NIH-funded HTORR Program

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 academic 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.

Our HTORR Program supports academic biomedical research investigators needs by providing: 

  • Access to a wide array of human biospecimens from any body system
  • Customized procurement in a variety of preservation formats including fresh, frozen, and fixed suitable for various analytical techniques
  • Reduced costs for tissue procurement
  • Technical support to design your studies utilizing human biospecimens
  • Letters of support and budgetary information for grant applications
  • Timely response to requests and 24/7 distribution

HTORR's Disease-Specific Focus

HTORR is also supported by a series of supplemental grants  for NDRI to serve as a human biospecimen resource for research focused specifically on Alzheimer’s disease (with funding from NIA), Autism Spectrum Disorder (ASD; with funding from NIMH) and HIV/AIDS (with funding from ORIP).
