Laboratory for Joint Tissue Repair and Regeneration

Our overall focus relates to common soft tissue injuries seen in athletes and active individuals.

Our laboratory investigates the basic cellular and molecular mechanisms of healing of joint tissues that are involved in common sports injuries, including tendon, ligament, meniscus, and cartilage. This research complements clinical practice, as injuries to these tissues are common, requiring surgical intervention for:

  • tendon repair
  • ligament reconstruction
  • cartilage repair and transplantation
  • meniscus repair and transplantation

A particular strength of the program is the close collaboration between clinician-scientists and a multidisciplinary team of investigators with expertise in cell biology, molecular biology, developmental biology, biomechanics and biomaterials, which informs research that has strong clinical relevance and that can ultimately be translated to clinical applications. As a clinician-scientist, my overall goal is to use our research findings to develop novel and innovative therapies for our patients.

Areas of Investigation

  • The effect of joint motion and strain loading on anterior cruciate ligament graft healing
  • Investigation of the role of tissue-specific activated endothelial cells on rotator cuff tendon healing and overuse tendonopathy
  • The role of Indian hedgehog signaling in ACL graft healing and rotator cuff tendon repair
  • Evaluation of novel materials for meniscus transplantation and replacement
  • Development of a mouse model of supraspinatus tendon impingement and overuse tendinopathy
  • Development of in vivo imaging techniques for small animals models, including fluorescent molecular imaging, multi-photon microscopy, and ultra-short TE MRI
  • Evaluation of stem cells derived from synovium, synovial fluid, and bone marrow for chondrogenesis
  • Use of a murine model of post-traumatic arthritis to evaluate cell-based therapy and lubricin-mimetics
  • Our murine models of rotator cuff tendon repair, ACL reconstruction, overuse tendonopathy, and post-traumatic arthritis now allow use of transgenic animals to examine the role of specific molecular factors in tissue healing and regeneration
