The Multi-Agency Tissue Engineering Sciences (MATES) is an ad hoc interagency working group that provides a platform where federal agencies can interact efficiently and effectively to exchange information on tissue engineering and regenerative medicine. MATES members coordinate efforts related to cell therapy, gene therapy, biomaterials, tissue engineering, regenerative medicine and organ on a chip from research and development to commercialization.  MATES holds monthly meetings to exchange information.


  • Facilitate communication across departments/agencies
  • Enhance cooperation and collaboration among federal agencies
  • Identify gaps and needs for tissue engineering and regenerative medicine research
  • Facilitate communication with regard to translation of research advances into practical applications
  • Monitor advances and identify and communicate needs for new technologies, standards and manufacturing science.


The MATES Interagency Working Group (IWG) was organized under the auspices of the Subcommittee on Biotechnology of the National Science and Technology Council (NSTC) in 2000 to serve as the means by which federal agencies involved in tissue engineering could stay informed of each other’s activities and coordinate their efforts in a timely and efficient manner. Since 2007, MATES has operated as an ad hoc interagency working group that continues with its original mission.
