Jay Dudhia is Associate Professor in Stem Cell Biology in the Department of Clinical Sciences and Services. His research interests are focussed on the ageing and mechanisms of equine tendinopathies and human osteoarthritis. A major area is in regenerative medicine to investigate the therapeutic potential of mesenchymal stem cells for tendon repair and cardiac stem cells for heart diseases.  These studies on tendon repair has led to the clinical use of mesenchymal stem cells for tendon injuries in the horse.  He has established a Veterinary Medicines Directorate approved stem cell laboratory for the manufacture of MSCs (equine and canine) for clinical use and advance the translation of regenerative strategies for the small and large veterinary clinic.

 

Jay graduated from Queen Elizabeth College University of London with a BSc Joint Honours degree in Biochemistry and Physiology and then gained a PhD in 1984 in Molecular Biology at Queen Elizabeth College (Kings College London). He took up a postdoctoral position with Professor Tim Hardingham in the Department of Biochemistry at the Kennedy Institute of Rheumatology (London) to pursue interests in the molecular changes in articular cartilage with ageing and in osteoarthritis, and the cloning and sequencing of a number of extracellular matrix proteins.

In 1997 he joined The ·¬ÇÑapp as a Senior Research Fellow to continue studies on articular and intervertebral disc cartilages with Professor Mike Bayliss in the Department of Veterinary Basic Sciences. In further collaborative work with Professor Roger Smith in the Department of Clinical Sciences and Services (CSS) he has investigated biomarkers of early tendon disease and in 2003 he moved to CSS to take up the opportunity to work closely with the equine clinic and run the tendon biology research group.

Following the pioneering studies at the RVC that led to the clinical use of MSCs for tendon injuries in the horse, he has established a Veterinary Medicine Directorate approved stem cell laboratory for the expansion and preparation of clinical grade MSCs for the equine and dog clinics to treat tendon and articular joint injuries.  The stem cell laboratory provides a service for stem cell treatment for the RVC and to private veterinary practices in the UK.

Jay holds an Honorary Senior Lectureship at University College London at the Institute of Orthopaedics and Musculoskeletal Science and in the Department of Chemistry. He is a member of a number of national societies including the British Society for Matrix Biology where he has previously served as a Committee and Board Member and honorary treasurer, the Tissue and Cell Engineering Society and the British Society for Cell Biology.  He recently worked as an Associate Editor for Cytometry Part A to edit a special issue of the Journal on Stem Cells across Species.  He has served on the review panels of research funding organisations and on several scientific journal editorial panels.  He also acts as a consultant to industry and academic Institutions in the area of genetic modified organisms (GMOs).  

He acts as an examiner, both internal (University of London) and external for PhD or MSc/MRes oral  exams.

 

Jay's research interests are on the extracellular matrices of articular cartilage and tendons.  His grant funded research in tendinopathies has been closely linked with the equine clinic and clinicians to enable the translation of the basic research to the clinic.  This has involved investigating age- and exercise-induced mechanisms of tendinopathies in the horse and has established ex vivo models of tendon injuries.  Recent work using such models has given insight into the mechanisms of failed healing seen in clinic for tendon injuries that are located within the tendon synovial sheath (intrasynovial injuries).  Current work is centred on the senescence associated secretory phenotype in equine tendon cells as a potential mechanism of age- and exercise-related tenon injuries.  His work in regenerative medicine has been to develop the therapeutic potential of mesenchymal stem cells for the repair of tendon injuries in large animal models of spontaneous and experimental tendon injuries.  Alongside this, he has been developing serological markers of the disease with equine clinical colleagues.

He has developed research with companion animal clinicians to investigate cardiac derived stem cells and induced pluripotent stem cells (iPSCs) with aim of translating their potential for heart repair or as in vitro (“disease in a dish”) models for developing and testing drugs.

His current research on cartilage is developing spectroscopic approaches for minimally invasive method of assessing early cartilage degeneration that is seen with osteoarthritis.  This patented approach to assess molecular alterations of the cartilage in very early disease prior to signs of erosion has led to Jay leading a proof-of-concept test of the successfully first-in-man use of the technology via minimally invasive surgery in the knees of osteoarthritis patients. Together with collaborators at University College London this technology is being taken forward for further technological and commercial development.

Jay holds a Postgraduate Certificate in Veterinary Education and is a Member of the Higher Education Academy.  He teaches on the BSc BioVeterinary Sciences, BVetMed and Gateway to BVetMed programmes on extracellular matrix biology, development, structure and function of cartilage and tendons and associated pathologies in man and equids. He also supervises laboratory based projects for BSc (years 2 and 3) and BVetMed undergraduates (RP2 rotation).  Jay acts as a departmental or non-departmental assessor for the annual appraisal system at the RVC for PhD students.

He has previously taught at UCL, Institute of Orthopaedics on the Intercalated BSc, MSc and distance learning programmes.

Jay is particularly interested in clinical applications of his research and has successful collaborations with both veterinary clinicians within the RVC animal hospitals as well as medical colleagues outside.  He has developed a programme of research with small animal clinicians on applications of stem cells in feline and canine myocardial diseases, and the stem cell laboratory that he established was with the aim of providing a clinical service in conjunction with the RVC animal hospitals and private veterinary clinics.
