    Generating High-Fidelity Cochlear Organoids from Human Pluripotent Stem Cells

    Using 3D cultures of human pluripotent stem cells, the authors sought to replicate key differentiation cues of cochlear specification. They found that timed modulations of Sonic Hedgehog and WNT signaling promoted ventral gene expression in otic progenitors.

    Synergistic Effect of Cold Gas Plasma and Experimental Drug Exposure Exhibits Skin Cancer Toxicity In Vitro and In Vivo

    Scientists identified effective combinations of experimental small molecules with cold gas plasma for therapy in dermato-oncology. The combination effects of selected drugs and cold gas plasma were investigated with respect to oxidative stress, invasion, and viability.

    Organelle Mapping in Dendrites of Human iPSC-Derived Neurons Reveals Dynamic Functional Dendritic Golgi Structures

    Investigators quantified the spatial and dynamic behavior of dendritic Golgi and endosomes during differentiation of human neurons generated from iPSCs. They revealed dynamic, functional Golgi structures in dendrites and a spatial map for investigating dendrite trafficking in human neurons.

    Extracellular Matrix Remodelling and Stiffening Contributes to Tumorigenesis of Salivary Carcinoma Ex Pleomorphic Adenoma—A Study Based on Patient-Derived Organoids

    Researchers examined extracellular matrix (ECM) modifications to elucidate the mechanism underlying carcinoma ex pleomorphic adenoma tumorigenesis. RNA-sequencing and bioinformatic analysis of organoids showed that differentially expressed genes were highly enriched in ECM-associated terms.

    A Multi-Mineral Intervention to Counter Pro-Inflammatory Activity and to Improve the Barrier in Human Colon Organoids

    Human colon organoids were maintained in a control culture medium alone or exposed to lipopolysaccharide with a combination of three pro-inflammatory cytokines to mimic the environment in the inflamed colon.

    Cell-Type Specific Defects in PTEN-Mutant Cortical Organoids Converge on Abnormal Circuit Activity

    The authors used human cortical organoids from different donors to identify cell-type-specific developmental events that were affected by heterozygous mutations in PTEN.

    Abstract

    Peripheral Neuron-Organoid Interaction Induces Colonic Epithelial Differentiation via Non-Synaptic Substance P Secretion

    Scientists investigated the biological significance of peripheral neurons in the formation of colonic organoids. Colonic organoids were co-cultured with hESC-derived peripheral neurons, resulting in the morphological maturation of columnar epithelial cells.
