Chief Scientific Officer and Director
Dr. Huard is the Chief Scientific Officer (CSO) and Director of the Center for Regenerative Sports Medicine at the Steadman Philippon Research Institute (SPRI) in Vail, Colorado. Dr. Huard is also an Affiliate Faculty, Department of Clinical and Biomedical Sciences, College of Veterinary Medicine, Colorado State University, Fort Collins Colorado. From 2015-2019, Dr. Huard was Professor, Distinguished Chair in Orthopaedic Research in the Department of Orthopaedic Surgery at the University of Texas Health Science Center at Houston (UTHealth) McGovern Medical School. Between 1995-2015, Dr. Huard held the Henry J. Mankin Endowed Chair in the Department of Orthopaedic Surgery and was the Director of the Stem Cell Research Center (SCRC). Dr. Huard also held numerous secondary appointments at the University of Pittsburgh and was also the Deputy Director for Cellular Therapies at the McGowan Institute for Regenerative Medicine.
Dr. Huard possesses extensive knowledge in the areas of gene therapy, tissue engineering, and regenerative medicine applications based on the use of muscle-derived stem/progenitor cells (MDSCs). The muscle-derived stem cells that his team isolated are currently undergoing testing in clinical trials for treatment of stress urinary incontinence (SUI) and myocardial infarction. More than 700 women suffering with SUI in Canada and the U.S. have volunteered for this stem cell therapy (Phase III Clinical Trial). Dr. Huard and his team have published over 400 peer reviewed papers, over 90 reviews/book chapters, and have over 900 abstracts accepted for presentation at national and international conferences (Citations 39577; h-index:106, i10-index: 340). The major research interests of SPRI’s Center for Regenerative Sports Medicine (CRSM) include: muscle stem cells isolation & characterization; bone & articular cartilage regeneration and repair; alleviation of muscle weakness in Duchenne muscular dystrophy (DMD); cardiac and skeletal muscle injury repair, regeneration, and fibrosis prevention; peripheral nerve regeneration; and the use of adult stem cells as a source for paracrine factors to alleviate the phenotypic changes associated with natural and accelerated aging. The main focus of the Center for Regenerative Sports Medicine laboratory is to develop biological medicine approaches to improve tissue repair after injury, disease and aging. The Huard lab uses a variety of technologies that fall into 4 different categories, including: Biologics (adult stem cells which include muscle derived stem cells, adipose derived stem cells as well as Bone Marrow Aspirate and Platelet Rich Plasma); Regenerative Medicine approaches (gene therapy approaches, CRSPR-Cas9, protein delivery like coacervate, microspheres, PA nanofibers and magnetic nanoparticles); Therapeutics (FDA approved drugs such as anti-fibrotic agents, pro-angiogenic agents, telomerase activity, (hTERT), senolytic and senomorphic drugs); and Animal Modelling (dystrophic and progeria mice models, super healer mice (MRL/MpJ), osteoarthritis model/microfracture, tibia fracture, calvarial defect and ovariectomy).

Contributions to Science
1) Duchenne muscular dystrophy (DMD) is a deadly genetic disease characterized by progressive muscle weakness due to a deficiency of dystrophin which usually leads to the loss of independent ambulation by 4-6 years of age, and a fatal outcome due to cardiac or respiratory failure by the third decade. I became very interested in the concept of restoring dystrophin expression to the dystrophin-deficient muscle of DMD patients via the transplantation of normal myoblasts; however, myoblast survival and regeneration capacities were very limited. Eventually, the use of a differential plating technique known as the preplating technique was used to identify a population of muscle-derived stem/progenitor cells that demonstrated high survival and regeneration capacities (1991-2000). DMD patients and animal model also acquire osteopenia, fragility bone fractures, and scoliosis, indicating that other musculoskeletal tissues are affected in DMD. Administration of glucocorticoids remains the gold standard therapy to delay the onset of the DMD pathology, but produces many unwanted side effects including weaker bones. Importantly, DMD patients become wheelchair-bound after they experience a bone fracture, emphasizing the importance of understanding these bone abnormalities in order to develop therapeutics to improve the quality of life of DMD patients. Therefore, we believe that identifying new therapeutic approaches that will work in conjunction with glucocorticoids to improve bone health in DMD patients can have a tremendous therapeutic value for DMD patients (2000-2020).

3) The identification of a population of muscle-derived stem cells (MDSCs) that showed superior survival, engraftment, and regenerative potential compared to myoblasts resulted in in-depth characterization of these cells. The cell population was isolated via the “preplate technique,” which takes advantage of the differential adhesion characteristics of the various cell populations found in skeletal muscle to collagen type 1-coated flasks. The population of MDSCs was isolated in a slowly adhering fraction of cells. These MDSCs express markers of stem cells but also display behaviors such as long-term proliferation, self-renewing ability, and multipotent differentiation. Since these cells have the ability to differentiate into multiple lineages and are highly resistant to stresses, they were tested for their ability to repair a variety of non-muscle tissues. Our research identified cells (endothelial and perivascular cells) within the blood vessel walls as the potential source of these stem/progenitor cells. More importantly, the technique for the isolation of MDSCs was patented and licensed to Cook Myosite, Inc. Cook has successfully been isolating human muscle-derived cells, and has applied these cells in clinical trials to treat over 700 women suffering from stress urinary incontinence (SUI) and also to treat patients who have suffered a myocardial infarction (2000-2014).

5) More recently, we have observed that stem cell depletion/exhaustion occurs during natural and accelerated aging as well as during the rapid progression of the disease in muscular dystrophy. We have also observed that transplantation of young MDSCs can be used to delay aging and the progression of diseases, such as muscular dystrophy. The mechanisms by which these cells delay aging and disease progress has been attributed to the potent paracrine effects of MDSCs in a variety of tissues (2012-2015).
