Thaddeus S. Stappenbeck, MD, PhD, AGAF

Councillor, Basic Research

Dr. Stappenbeck’s expertise at the intersection of stem cell biology, microbiology and immunology has propelled his lab to define the stages and mechanisms of intestinal repair following injury. He has developed predictive diagnostics and earlystage therapeutics for inflammatory bowel disease (IBD) and idiopathic pulmonary fibrosis. He has determined mechanisms for the effects of intestinal microbes on repair and prevention of infection, discovered microbes that inhibit proper regeneration and created a cell culture system for human intestinal stem cells that is used by labs around the world. He moved to Cleveland Clinic to partner with the world class clinicians and scientists in this institution to accelerate partnerships to create new concepts for therapy and prevention of inflammatory disease. Here he additionally founded Mobius Care, Inc., a company that is devoted to developing personalized care for IBD. His deep expertise in stem cell biology, infectious disease and immunology enable the translation of his discoveries to areas of general human health and well-being including aging. For this goal, rejuvenation of stem cells and prevention of the damaging effects of infection to stem cells are important approaches for his research program.
