Dr. Klaus Kaestner

Biography

Klaus H. Kaestner is a prominent researcher at the University of Pennsylvania's Perelman School of Medicine, focusing on genetics and epigenomics. His laboratory employs modern genetic techniques to investigate the molecular mechanisms underlying organogenesis and physiology of the liver, pancreas, and gastrointestinal tract. His work addresses key disease areas, including diabetes and cancer, by exploring ways to rejuvenate human pancreatic beta-cells, which are critical in diabetes management. Kaestner's research aims to increase functional beta-cell mass and replicate adult human beta-cells, as diabetes continues to escalate globally. The laboratory is particularly interested in the age-related decline of beta-cell function and the impact that certain gene expressions have on beta-cell hyperplasia. Additionally, his studies also delve into the cellular mechanisms involved in the proliferation and differentiation of the gastrointestinal epithelium, highlighting the roles of telocytes as essential providers of Wnt signals for intestinal stem cells. Through innovative genetic approaches, Kaestner seeks to improve understanding of liver regeneration in response to toxic injuries, developing better therapies for chronic liver diseases. His work not only gives insights into fundamental biological processes but also aims for clinical relevance in treating diseases.
