    Analysis of Off-Tumor Toxicities of T Cell-Engaging Bispecific Antibodies via Donor-Matched Intestinal Organoids and Tumoroids

    Investigators showed that patient-derived intestinal organoids and tumouroids supplemented with immune cells could be used to study the on-target off-tumour toxicities of T cell-engaging bispecific antibodies (TCBs).

    Kidney Organoid Models Reveal Cilium-Autophagy Metabolic Axis as a Therapeutic Target for PKD Both In Vitro and In Vivo

    Single-cell analysis revealed that a myriad of metabolic changes occurred during cystogenesis, including defective autophagy. Experimental activation of autophagy via ATG5 overexpression or primary cilia ablation significantly inhibited cystogenesis in olycystic kidney disease kidney organoids.

    Abstract

    Human Cerebellar Organoids with Functional Purkinje Cells

    Scientists reported a human organoid model capable of developing the complex cellular diversity of the fetal cerebellum, including a human-specific rhombic lip progenitor population that have never been generated in vitro prior to this study.

    Human Apical-Out Nasal Organoids Reveal an Essential Role of Matrix Metalloproteinases in Airway Epithelial Differentiation

    Researchers presented a human apical-out airway organoid using a biochemically defined hybrid hydrogel system. During human nasal epithelial progenitor cell differentiation, the gel gradually degraded, leading to the organoid apical surfaces facing outward.

    Spatiotemporal Modulation of Growth Factors Directs the Generation of Multilineage Mouse Embryonic Stem Cell-Derived Mammary Organoids

    Researchers adapted the skin organoid model, inducing the dermal mesenchyme to transform into mammary-specific mesenchyme via the sequential activation of Bone Morphogenetic Protein 4 and Parathyroid Hormone-related Protein and inhibition of hedgehog signaling.

    Human Retinal Organoids with an OPA1 Mutation Are Defective in Retinal Ganglion Cell Differentiation and Function

    The authors generated isogenic iPSCs carrying the hotspot OPA1 c.2708_2711delTTAG mutation and found that the mutant variant caused defective initial and terminal differentiation and abnormal electrophysiological properties of organoid-derived retinal ganglion cells.
