    Glucose Dissociates DDX21 Dimers to Regulate mRNA Splicing and Tissue Differentiation

    Glucose elevation during differentiation was associated with DDX21 re-localization from the nucleolus to the nucleoplasm where DDX21 assembled into larger protein complexes containing RNA splicing factors.

    Targeting Src Reactivates Pyroptosis to Reverse Chemoresistance in Lung and Pancreatic Cancer Models

    Researchers demonstrated that β5-integrin repressesed chemotherapy-induced canonical pyroptosis to confer cancer chemoresistance through ASAH2-driven sphingolipid metabolic reprogramming.

    Abstract

    Senescent Cells Perturb Intestinal Stem Cell Differentiation through Ptk7 Induced Noncanonical Wnt and YAP Signaling

    Using intestinal organoids as a model of tissue regeneration, the authors showed that senescence-associated secretory phenotype factors released by senescent fibroblasts deregulated stem cell activity and differentiation and ultimately impaired crypt formation.

    A BMP-2–Triggered In Vivo Osteo-Organoid for Cell Therapy

    Investigators demonstrated that constructing in vivo osteo-organoids by implanting bone morphogenetic protein–2 (BMP-2)–loaded scaffolds into the internal muscle pocket near the femur of mice supported the growth and subsequent harvest of therapeutically useful cells.

    A Cdh3-β-Catenin-Laminin Signaling Axis in a Subset of Breast Tumor Leader Cells Control Leader Cell Polarization and Directional Collective Migration

    From single-cell sequencing analyses, scientists found that leader cells were heterogeneous and identified and isolated a keratin 14- and cadherin-3-positive subpopulation sufficient to lead collective migration.

    Epithelial Plasticity Enhances Regeneration of Committed Taste Receptor Cells Following Nerve Injury

    Researchers revealed that injury caused by glossopharyngeal nerve transection triggered the remaining differentiated K8-positive taste receptor cells to dedifferentiate and acquire transient progenitor cell-like states during regeneration.
