AR3T is an NIH-funded resource center that helps to develop research collaborations, provides educational opportunities, and funds pilot projects and technology development projects that will benefit the research community. The alliance of our four institutions (the University of Pittsburgh, Stanford University, Mayo Clinic, and the University of Texas at Austin) comprising over twenty laboratories, is in place to support these efforts. The overarching goal is to support the expansion of scientific knowledge, expertise and methodologies across the domains of rehabilitation science and regenerative medicine.
