Development, Aging and Regeneration Program

developing human islets

Probing biology and disease

Our cells constantly receive cues from both inside and outside the body, prompted by conditions such as injury, aging, infection, stress or even food.

To adjust to these cues, cells send and receive signals through biological pathways. Our research into the codes and cell changes associated with normal development and aging, and distinguishing them from those linked to disease and disability, will lead to new strategies to protect our health.

The model model organism - the fruit fly and its beating heart

Directors' statement

We are using model organisms—mice, fish, flies, worms and human stem cells to (1) unravel gene functions linked to mutations and epigenetic factors; (2) explore the development and regenerative capacity of the brain, heart, muscles, pancreas, limbs, liver and other organs; and (3) probe the biology of aging and organ/tissue maintenance to maintain a well-functioning organism. These insights provide the tools needed to uncover novel therapeutic targets for heart disease, neurodegeneration, muscle disorders, diabetes, cancer and other debilitating diseases.
