    Development of Human Pluripotent Stem Cell-Derived Hepatic Organoids as an Alternative Model for Drug Safety Assessment

    Researchers generated human PSC-derived hepatic organoids (hHOs) with a high drug metabolic ability. They established a two-step protocol to produce hHOs from human PSCs for long-term expansion and drug testing.

    The Ciliary Gene INPP5E Confers Dorsal Telencephalic Identity to Human Cortical Organoids by Negatively Regulating Sonic Hedgehog Signaling

    Investigators showed that cilia were present on the apical surface of radial glial cells in human fetal forebrain. Interfering with cilia signaling in human organoids by mutating the INPP5E gene led to the formation of ventral telencephalic cell types instead of cortical progenitors and neurons.

    Distinct Accumulation of Nanoplastics in Human Intestinal Organoids

    By exposing human intestinal organoids to polystyrene nanoplastics with concentrations of 10 and 100 μg/mL, researchers presented evidence of their distinct accumulation in various type cells in intestinal organoids, then causing the cell apoptosis and inflammatory response.

    Modeling Immune Cytotoxicity for Cholangiocarcinoma with Tumor-Derived Organoids and Effector T Cells

    Scientists developed a co-culture method with patient-derived cholangiocarcinoma organoids and immune cells, which could represent anti-cancer immunity in vitro.

    Establishment of Organoids from Human Epithelioid Sarcoma with the Air-Liquid Interface Organoid Cultures

    Organoids from the epithelioid sarcoma could be serially cultured and maintained in collagen type 1 gels for more than three passages. Developed orthotopic tumor xenografts were detected in the NOD-scid IL2Rgnull mice.

    A Saponin from Astragalus Promotes Pancreatic Ductal Organoids Differentiation into Insulin-Producing Cells

    The authors established mouse pancreatic ductal organoids with progenitor characteristics and an insulin promoter-driven enhanced green fluorescent protein reporter system to screen astragalus saponin components for monomers that could promote insulin-producing cell differentiation.

    Screening of Organoids Derived from Patients with Breast Cancer Implicates the Repressor NCOR2 in Cytotoxic Stress Response and Antitumor Immunity

    High nuclear receptor corepressor 2 (NCOR2) in the tumors of patients with breast cancer predicted chemotherapy refractoriness, tumor recurrence and poor prognosis.

    Organoids and Regenerative Hepatology

    Scientists discuss various historical aspects of 3D organoid culture, how it has been applied to the hepatobiliary system, and how organoid technology intersects with the emerging global field of liver regenerative medicine.

    Abstract

    Genetically Engineered Cellular Models of Prion Propagation

    When coupled with the ability to propagate prions in cells or organoids derived from stem cells, these next-generation cellular models should provide an ideal paradigm for identifying small molecules and other biological therapeutics capable of interfering with prion replication in animal and human prion disorders.
