R-spondin 1 and noggin facilitate expansion of resident stem cells from non-damaged gallbladders.

ABSTRACT: Pioneering studies within the last few years have allowed the in vitro expansion of tissue-specific adult stem cells from a variety of endoderm-derived organs, including the stomach, small intestine and colon. Here we derived organoids from mouse gallbladder tissue (gallbladder organoids), from mouse liver (including the extrahepatic biliary ducts and gallbladder; liver organoids) and from mouse small intestine tissue (intestinal organoids). RNA was prepared from these organoids and used to assay expression of 21,258 genes using Affymetrix gene expression arrays. RNA was also prepared from mouse gallbladder, liver and small intestine tissues and used to assay gene expression in these tissues. Finally, gallbladder organoids were induced to differentiate by removing R-spondin 1 and noggin from the culture media and subjected to gene expression array analysis.

Tissue specific gene expression of epithelial tuft cells from small intestine and gallbladder in mouse

Project description:Rare chemosensory epithelial cells called tuft cells have known roles in small intestinal regulation of type 2 cytokine producing Group 2 innate lymphoid cells. To understand the phenotype of tuft cells in another tissue, the extrahepatic biliary tree, we performed RNAseq analysis on tuft cells and non-tuft epithelial cells from small intestine and gallbladder of the mouse.

In vitro expansion of cirrhosis derived liver epithelial cells reveals progenitor-like properties [methylation]

Project description:By looking at the methylation sites in normal human liver hepatocytes, cholangiocytes, cultured gallbladder organoids, cirrhotic liver organoids and cirrhotic liver cells, we are looking at the cell origin of cirrhotic liver cells.

Benary2021 - tissue dynamics of the hepato-pancreato-biliary organ system

Project description:Single cell-based studies have revealed tremendous cellular heterogeneity in stem cell and progenitor compartments, suggesting continuous differentiation trajectories with intermixing of cells at various states of lineage commitment and notable degree of plasticity during organogenesis. The hepato-pancreato-biliary organ system relies on a small endoderm progenitor compartment that gives rise to a variety of different adult tissues, including liver, pancreas, gallbladder, and extra-hepatic bile ducts. Experimental manipulation of various developmental signals in the mouse embryo underscored important cellular plasticity in this embryonic territory. This is also reflected in the existence of human genetic syndromes as well as congenital or environmentally-caused human malformations featuring multiorgan phenotypes in liver, pancreas and gallbladder. Nevertheless, the precise lineage hierarchy and succession of events leading to the segregation of an endoderm progenitor compartment into hepatic, biliary, and pancreatic structures are not yet established. Here, we combine computational modelling approaches with genetic lineage tracing to assess the tissue dynamics accompanying the ontogeny of the hepato-pancreato-biliary organ system. We show that a multipotent progenitor domain persists at the border between liver and pancreas, even after pancreatic fate is specified, contributing to the formation of several organ derivatives, including the liver. Moreover, using single-cell RNA sequencing we define a specialized niche that possibly supports such extended cell fate plasticity.
