    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.

    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.

    Bacterial Detection by NAIP/NLRC4 Elicits Prompt Contractions of Intestinal Epithelial Cell Layers

    Researchers showed that untransformed intestinal epithelial cell layers initiate immediate focal contractions, affecting hundreds to thousands of epithelial cells, in response to bacterial infection.

    Abstract

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

    Investigators report that SARS-CoV-2 productively infected 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.

    Morphological and Molecular Characteristics of Spheroid Formation in HT-29 and Caco-2 Colorectal Cancer Cell Lines

    Colorectal cancer spheroids were developed using hanging drop and forced floating in serum-free and non-attachment conditions and their morphological features were evaluated by scanning electron microscopy.

    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.
