Repair and regeneration of injured heart and diseased pancreas

Adult stem cells and regulated gene therapy adeno associated virus mediated gene delivery

Current Research

The goal of our research is to discover innovative means of diabetes reversal by regenerating functional insulin-producing cells. We aim to achieve this goal with the use of adult stem cells and gene transfer, and to define the mechanisms underlying the therapeutic effects.

Diabetes is among the most common endocrine disorders affecting about 20 million Americans (6.2% of the population) and 120 million people worldwide. Regardless of the forms of diabetes, hyperglycemia is accompanied by complete depletion (type 1) or significant loss (type 2) of functional pancreatic beta cells. Current therapies mainly rely on exogenous insulin administration or pancreas transplantation to normalize blood glucose, and no method is yet available to replace endogenous beta cells.

Recent investigations have uncovered tremendous potential of adult stem cells in tissue repair and regeneration. In particular, bone marrow stem cells possess pluripotency, are easy to procure from patients, and can be used for auto-transplantation without the need for immunosuppression. We believe the combination of adult stem cells and gene therapy will facilitate formation of new insulin-producing cells as a potential cure for diabetes.

We are currently using mouse models (chemical-induced diabetes or non-obese diabetic mice) to test the efficacy of this approach in type 1 diabetes. Integrative methodologies are applied to understand the cellular and physiological mechanisms, including molecular cloning, stem cell culture, gene transfer, immunohistochemistry, animal surgery and glucose monitoring.
