    Single-Cell Analyses Define a Continuum of Cell State and Composition Changes in the Malignant Transformation of Polyps to Colorectal Cancer

    A large fraction of polyp and colorectal cancer (CRC) cells exhibited a stem-like phenotype, and investigators defined a continuum of epigenetic and transcriptional changes occurring in these stem-like cells as they progressed from homeostasis to CRC.

    Lymphatics Act as a Signaling Hub To Regulate Intestinal Stem Cell Activity

    Employing in vivo loss of function and lymphatic:organoid cocultures, researchers showed that crypt lymphatics maintained intestinal stem cells and inhibited their precocious differentiation.

    Cell and Chromatin Transitions in Intestinal Stem Cell Regeneration

    Investigators showed that goblet, Paneth, and enteroendocrine cells arose by multilineage priming in common precursors, followed by selective access at thousands of cell-restricted cis-elements.

    Abstract

    Human 2D Crypt Model for Assaying Intestinal Stem Cell Proliferation and Differentiation

    A planar, self-renewing human intestinal monolayer platform based on primary adult gastrointestinal stem cells, termed the 2D crypt model, was developed to screen for the effects of various compounds on the intestinal epithelium.

    Hederacoside C Ameliorates Colitis via Restoring Impaired Intestinal Barrier Through Moderating S100A9/MAPK and Neutrophil Recruitment Inactivation

    The authors investigated how hederacoside C attenuated intestinal inflammation in vivo and in vitro.

    Patient-Derived Organoids Identify an Apico-Basolateral Polarity Switch Associated with Survival in Colorectal Cancer

    Researchers reported that mucinous colorectal carcinoma tumors maintained a robust apico-basolateral polarity as they spread in the peritumoral stroma or organotypic collagen-I gels.

    Abstract

    Chicken-Derived RSPO1 and WNT3 Contribute to Maintaining Longevity of Chicken Intestinal Organoid Cultures

    Based on the limited homology between mammalian and avian RSPO1, scientists expected that chicken-derived factors were required for chicken intestinal organoid cultures.

    Essential Roles of TDO2 in Gastric Cancer: TDO2 Is Associated with Cancer Progression, Patient Survival, PD-L1 Expression, and Cancer Stem Cells

    Tryptophan 2,3-dioxygenase (TDO2) expression was correlated with both progressive disease and clinical outcome, and its expression was an independent predictor of prognosis in gastric cancer.

    Spef1/CLAMP Binds Microtubules and Actin-Based Structures and Regulates Cell Migration and Epithelia Cell Polarity

    The authors outline Sperm flagella protein-1 (Spef1)/calponin homology and microtubules-associated protein (CLAMP) structure and expression in several cellular models.
