    Cholangiocyte Organoids Can Repair Bile Ducts after Transplantation in the Human Liver

    Using single-cell RNA sequencing, investigators showed that primary human cholangiocytes displayed transcriptional diversity that is lost in organoid culture.
    [Science]

    Abstract

    Long-Term Maturation of Human Cortical Organoids Matches Key Early Postnatal Transitions

    Based on genome-wide analysis of the epigenetic clock and transcriptomics, as well as RNA editing, researchers observed that 3D human cortical organoids reached postnatal stages between 250 and 300 days, a timeline paralleling in vivo development.

    Abstract

    HIF-1α-Induced Expression of m6A Reader YTHDF1 Drives Hypoxia-Induced Autophagy and Malignancy of Hepatocellular Carcinoma by Promoting ATG2A and ATG14 Translation

    Specific variations in YTHDF1 expression were detected in YTHDF1-overexpressing, -knockout, and -knockdown human hepatocellular carcinoma (HCC) cells, HCC organoids, and HCC patient-derived xenograft murine models.

    Abstract

    A Bladder Cancer Patient-Derived Xenograft Displays Aggressive Growth Dynamics In Vivo and in Organoid Culture

    Researchers established and molecularly characterized CoCaB 1, an aggressive cisplatin-resistant muscle-invasive bladder cancer patient-derived xenograft and companion organoid system.

    Collagen I Triggers Directional Migration, Invasion and Matrix Remodeling of Stroma Cells in a 3D Spheroid Model of Endometriosis

    Scientists used endometrial stromal, primary endometriotic stromal, epithelial endometriotic and co-culture spheroids to mimic the architecture of endometrium, and either collagen I or Matrigel to model ectopic locations.
