Chemical Conversion of Human Epidermal Stem Cells into Intestinal Goblet Cells for Modeling Mucus-Microbe Interaction and Therapy

The authors generated intestinal goblet cells from human epidermal stem cells with two small molecular inhibitors Repsox and CHIR99021 in the presence of basic fibroblast growth factor and bone morphogenetic protein 4 at high efficiency of conversion for a short time.

Dickkopf-2 Regulates the Stem Cell Marker LGR5 in Colorectal Cancer via HNF4α1

Scientists report a Wnt ligand, Dickkopf-2 (DKK2) was essential for developing colorectal cancer stemness. Genetic depletion of Dkk2 in intestinal epithelial or stem cells reduced tumorigenesis as well as expression of the stem cell marker genes including Lgr5 in a model of colitis-associated cancer.

miR-98-5p Inhibits Gastric Cancer Cell Stemness and Chemoresistance by Targeting Branched-Chain Aminotransferases 1

The expression of miR-98 in CD44+ gastric cancer stem cells (GCSCs) was verified by RT-PCR. The miR-98 was overexpressed in CD44+ GCSCs by Lentivirus.

Human Pluripotent Stem Cell-Derived Intestinal Organoids Model SARS-CoV-2 Infection Revealing a Common Epithelial Inflammatory Response

Scientists report that SARS-CoV-2 productively infects both proximally and distally patterned human induced pluripotent stem cell-derived intestinal organoids , leading to the release of infectious viral particles while stimulating a robust transcriptomic response, including a significant upregulation of interferon-related genes that appeared to be conserved across multiple epithelial cell types.

Efferocytosis by Paneth Cells within the Intestine

Through a series of studies spanning in vitro efferocytosis, ex vivo intestinal organoids, and in vivo Cre-mediated deletion of Paneth cells, researchers showed that Paneth cells mediate apoptotic cell uptake of dying neighbors.
