Human Tissue and Organ Research Resource (HTORR)

The Human Tissue and Organ Research Resource (HTORR) program provides normal and diseased human tissues to investigators at research centers.  HTORR supports the procurement, preservation, and distribution of human tissue and organs for basic and clinical research.  While the resource maintains a biorepository of fixed and frozen tissue samples, procurement of fresh tissue is the main activity.  At present the resource is made available through the National Disease Research Interchange (NDRI) under an National Institutes of Health (NIH)-wide program.

More information about this resource is available at National Disease Research Interchange (NDRI)

Main Areas of Focus

The two main areas served by HTORR relevant to the NIAID are HIV research and basic immunology research:

  • For HIV research, HTORR supplies tissue from HIV infected individuals and procures organs for transplantation
  • For basic immunology projects, HTORR supplies normal human lymphoid tissue


  • Repository of various frozen and fixed tissue samples

Who Can Use This Resource

  • Each prospective researcher completes an application process to determine whether the project falls within NDRI’s capabilities and mission.  

How To Get Started

  • Requests for tissues can be made via the NDRI website.
