Gonzalez of North Carolina State University as she discusses the recently published paper entitled "HOPX+ injury-resistant intestinal stem cells drive epithelial recovery after severe intestinal ischemia" with EIC Prof. Mark Frey. This paper supports that rISCs are resistant to ischemic injury and likely an important source of cellular renewal following near-complete epithelial loss. Furthermore, the authors have evidence that HOPX controls ISC activity state and may be a critical signaling pathway during ISC-mediated repair. Finally, they use multiple novel methods to evaluate ISCs in a translationally relevant large animal model of s...2022-06-2425 minAmerican Journal of Physiology-Gastrointestinal and Liver Physiology PodcastGot Guts: A new approach to treat gastrointestinal motility disordersLooking for a new pharmacological approach to treat gastrointestinal motility disorders?

2022-04-2826 minAmerican Journal of Physiology-Gastrointestinal and Liver Physiology PodcastGot Guts: Behind the science with an Organoid DivaMany times we read a manuscript but don’t really get to know the amazing author behind the great science. Behind those black typewritten letters that spell a scientists name lies a person that is usually creative, intelligent, quirky, and fun. This is certainly the case with the author of “Use of human tissue stem cell-derived organoid cultures to model enterohepatic circulation”, Dr. Sarah Blutt. Please listen in as we learn a little bit about one of the fields Organoid Divas and what makes her tick as we discuss organoids as a biological toll booth and other topics.
