In a rapidly evolving era of single cell technologies, the authors of "Stiffness is associated with hepatic stellate cell heterogeneity during liver fibrosis" explain the mechanism of an amplification loop during liver fibrosis. By deciphering how stiffness macro and microscopic heterogeneity promote differential gene expression in hepatic stellate cell sub-populations, the authors find a novel stiffness-promoted molecule involved in liver fibrosis progression. Get to know authors Dr. Enis Kostallari and Dr. Vijay Shah of the Mayo Clinic as they discuss their recently published manuscript and what life is like as a researcher with Editor-in-Chief Professor Mark Frey.

Get to know senior author Dr. Liara M. 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 severe intestinal injury and provide evidence for the potential role of rISCs as therapeutic targets.

Three investigators at Children's Hospital Los Angeles, Nandini Girish, Dr. Cambrian Liu, and Dr. Brent Polk, talk about their recent work to visualize the fates and functions of epithelial stem cells in models of inflammatory bowel disease with Editor-in-Chief Professor Mark Frey. The investigators discuss their diverse backgrounds, reveal how they started the work, and begin a spirited debate on the relative values of minivans and dogs and cats.

Many 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.
