    Bladder Cancer Organoids as a Functional System to Model Different Disease Stages and Therapy Response

    Using patient-derived organoid cultures from different bladder cancer stages and grades, integrative analysis of drug response profiles with matched genomic analyses were carried out to determine enrichment thresholds for candidate markers of therapy response and resistance.

    Human Brain Organoid Model of Maternal Immune Activation Identifies Radial Glia Cells As Selectively Vulnerable

    The authors established a human 3D in vitro model of maternal immune activation by treating induced pluripotent stem cell-derived dorsal forebrain organoids with a constitutively active form of interleukin (IL)-6, Hyper-IL-6.

    Organoids from Mouse Molar and Incisor As New Tools to Study Tooth-Specific Biology and Development

    The authors established tooth organoids from early-postnatal mouse molar and incisor, which were long-term expandable, expressed dental epithelium stem cell markers, and recapitulated key properties of the dental epithelium in a tooth-type-specific manner.

    Neuro-Mesodermal Assembloids Recapitulate Aspects of Peripheral Nervous System Development In Vitro

    Investigators described a novel neuro-mesodermal assembloid model that recapitulated aspects of peripheral nervous system development such as neural crest cell induction, migration, and sensory as well as sympathetic ganglion formation.

    Salivary Gland Cancer Organoids Are Valid for Preclinical Genotype-Oriented Medical Precision Trials

    Researchers enrolled 29 patients, including 24 with salivary gland cancers and 5 with benign tumors. Resected tumors were subjected to organoid and monolayer cultures, as well as whole-exome sequencing.
