    An
    Organoid Biobank of Neuroendocrine Neoplasms Enables Genotype-Phenotype Mapping

    Scientists established 25 lines of neuroendocrine carcinoma (NEN) organoids and performed their comprehensive molecular characterization. Gastroenteropancreatic-NEN organoids recapitulated pathohistological and functional phenotypes of the original tumors.

    Genetically
    Defined, Syngeneic Organoid Platform for Developing Combination Therapies for Ovarian Cancer

    By engineering mouse fallopian tube epithelial organoids using lentiviral gene transduction and/or CRISPR/Cas9 mutagenesis, researchers generated multiple high grade serous tubo-ovarian carcinoma (HGSC) models exhibiting mutational combinations seen in HGSC patients.

    Abstract

    Capturing Cardiogenesis in Gastruloids

    The authors showed that mouse embryonic stem cells could be coaxed to robustly undergo fundamental steps of early heart organogenesis with an in vivo-like spatiotemporal fidelity.

    and Biobanking of Patient-Derived Glioblastoma Organoids and Their Application in CAR T Cell Testing

    Scientists describe detailed procedures for generating glioblastoma organoids from surgically resected patient tumor tissue using a chemically defined medium without cell dissociation.
    [Nature Protocols]

    Abstract

    mTORC1
    Activation in Lung Mesenchyme Drives Sex- and Age-Dependent Pulmonary Structure and Function Decline

    Investigators profiled a lymphangioleiomyomatosis (LAM) lung compared to an age- and sex-matched healthy control lung as a hypothesis-generating approach to identify cell subtypes that are specific to LAM.

    Lethality between MyD88 Loss and Mutations in Wnt/β-Catenin Pathway in Intestinal Tumor Epithelial Cells

    The authors clarified the mechanisms by which epithelial MyD88 contributed to intestinal tumor formation and to address whether MyD88 could be a therapeutic target of colorectal cancer.
    [Oncogene]

    Abstract

    Drug
    Inhibition of SARS-CoV-2 Replication in Human Pluripotent Stem Cell-Derived Intestinal Organoids

    Researchers employed human intestinal organoids derived from PSCs to dissect SARS-CoV-2 pathogenesis and its inhibition by remdesivir, one of the leading drugs investigated for treatment of COVID-19.

    Abstract

    Endocannabinoid
    Signaling in Stem Cells and Cerebral Organoids Drives Differentiation to Deep Layer Projection Neurons via CB1 Receptors

    Scientists investigated the role of endocannabinoid signaling in mouse pluripotent embryonic stem cell-derived neuronal differentiation. Incubation with CB1 receptor agonists during human iPSC-derived cerebral organoid formation promoted the expansion of BCL11B+ neurons.

    Abstract

    Evaluation of Chemotherapy and P2Et Extract Combination in Ex-Vivo
    Derived Tumor Mammospheres from Breast Cancer Patients

    Investigators evaluated the ex vivo response of patient tumor-derived organoids (or mammospheres) to chemotherapy alone or in combination with P2Et. A xenotransplant model engrafted with MDA-MB-468 was used to evaluate the in vivo activity of P2Et.

    Abstract

    Integrin-Mediated Adhesion and Mechanosensing in the Mammary Gland

    As the mechanical properties of a complex tissue environment are challenging to replicate in vitro, emphasis has been placed on studies conducted in vivo or using organoid models.
