About Araz Toumadje
Dr. Toumadje is developing a Human-Induced Pluripotent Stem Cell Core, which will enable Transplant to use a patient’s own tissues to create healthy cells that can help the patient overcome disease. Development of the iPSC Core is urgent, as in vitro technologies are badly needed for larger-scale generation of healthy, insulin-producing beta cells to compensate for the shortage of pancreas donors. In the iPSC Core, Dr. Toumadje is currently researching the generation of beta cells from human adipose-derived pluripotent stem cells and derivation of iPSC from islet and acinar cells. He is also part of the Cellular Therapy and Transplant Core.
Dr. Toumadje’s past research includes differentiation of human embryonic stem cells to alveolar type II lung cells, neural stem cells, and dopaminergic neurons. He has developed a new culture system for pluripotent stem cells; a novel in vitro model to study human embryotoxicity; a bead-based flow cytometric assay for telomerase enzyme; and circular dichroism spectroscopy.
Dr. Toumadje has experience both in research laboratories and in industry. He has won two Small Business Innovative Research Awards and a Corporate Product & Technology Development Award. His business experience aids him in translating research success into accessible real-world results.
When he is not working, Dr. Toumadje enjoys watching old movies, spending time with his family, and playing with his grandchildren.
