Heinrich Jaspar

The Jasper lab uses the fruit fly Drosophila melanogaster as a model system to explore the basic biology of stem cell function and regeneration and to identify mechanisms of age-related stem cell dysfunction. Hypotheses emerging from this work are then tested in mammalian systems. We have identified signaling mechanisms that govern the response of stem cells to environmental stress, to nutrient conditions, and to the commensal microbiota as areas of intervention to preserve tissue health. We have also identified intervention strategies based on these findings that can extend lifespan and maintain stem cell populations in flies and mice.
