    The Spindle Assembly Checkpoint Is a Therapeutic Vulnerability of CDK4/6 Inhibitor–Resistant ER+ Breast Cancer with Mitotic Aberrations

    Investigators developed a panel of CDK4/6i-resistant breast cancer cell lines and patient-derived organoids and demonstrated that a subset of resistant models accumulated mitotic segregation errors and micronuclei.

    Spatiotemporal Dynamics of Self-Organized Branching in Pancreas-Derived Organoids

    Using single primary murine pancreatic ductal adenocarcinoma cells embedded in a collagen matrix and adapted media supplementation, scientists generated organoids that self-organized into highly branched structures displaying a seamless lumen connecting terminal end buds.

    MAB21L4 Deficiency Drives Squamous Cell Carcinoma via Activation of RET

    Investigators performed a transcriptome-wide screen for genes of unknown function that possess inverse expression patterns in differentiating keratinocytes compared with cutaneous squamous cell carcinomas.

    Organoids Capture Tissue-Specific Innate Lymphoid Cell Development in Mice and Humans

    Murine intestinal and pulmonary organoids were harnessed to demonstrate that the epithelial niche was sufficient to drive tissue-specific maturation of all innate lymphoid cell groups in parallel, without requiring subset-specific cytokine supplementation.

    Modeling Biochemical Gradients In Vitro to Control Cell Compartmentalization in a Microengineered 3D Model of the Intestinal Epithelium

    Researchers presented a new in vitro model of the small intestine based on primary epithelial cells, apically accessible, with native tissue mechanical properties and controlled mesh size, 3D villus-like architecture, and precisely controlled biomolecular gradients of the intestinal stem cell niche.

    Abstract

    Rapid and Robust Directed Differentiation of Mouse Epiblast Stem Cells into Definitive Endoderm and Forebrain Organoids

    The authors examined the potential of mouse epiblast stem cells cultured in media containing Wnt pathway inhibitors as a starting point for directed differentiation.
    [Development]

    Abstract

    Heterogeneity, Inherent, and Acquired Drug Resistance in Patient-Derived Organoid Models of Primary Liver Cancer

    52 organoids were established from 153 primary liver cancer patients. Compared with establishing patient-derived xenograft models, establishing organoids of hepatocellular carcinoma showed a trend toward a higher success rate and took less time.
    [Cellular Oncology]

    Abstract

    3D Proximal Tubule-on-Chip Model Derived from Kidney Organoids with Improved Drug Uptake

    Investigators reported a method for creating a perfusable 3D proximal tubule model composed of epithelial cells isolated from kidney organoids matured under static conditions.
    [Scientific Reports]
