Research Summary

The work pursued in our laboratory primarily focusses on stem cells. We are interested in studying stem cell derived hematopoietic cell and insulin producing cells. Type 1 diabetes is one of the most devastating chronic diseases which costs billions of dollars every year. By establishing a stem cell based source of insulin producing cells, we might be able to treat many patients who would otherwise remain untreatable. Similarly, induced pluripotent stem cells are a novel source of hematopoietic cells for the treatment of leukemia and other hematopoietic malignancies. We have established nopvel approaches for the derivation of mouse and human hematopoietic cells. Our lab has several in vivo models for probing the efficacy of these cells in vivo.
