    TOP STORY

    Screening for Modulators of the Cellular Composition of Gut Epithelia via Organoid Models of Intestinal Stem Cell Differentiation

    The authors showed that druggable biological targets and small-molecule regulators of intestinal stem cell differentiation could be identified via multiplexed phenotypic screening using thousands of miniaturized organoid models of intestinal stem cell differentiation into Paneth cells.

    Orthogonally Induced Differentiation of Stem Cells for the Programmatic Patterning of Vascularized Organoids and Bioprinted Tissues

    Researchers showed that patterned organoids and bioprinted tissues with controlled composition and organization could be generated by simultaneously co-differentiating hiPSCs into distinct cell types via the forced overexpression of transcription factors, independently of culture-media composition.

    Abstract

    Application of an iPSC-Derived Organoid Model for Localized Scleroderma Therapy

    An hiPSC-derived epithelial and mesenchymal organoid model in a 3D culture system for localized scleroderma therapy was established.

    Downregulation of Neurodevelopmental Gene Expression in iPSC-Derived Cerebral Organoids upon Infection by Human Cytomegalovirus

    Scientists determined the impact of human cytomegalovirus infection on the transcriptome of developing neurons in an organoid model system. Cell populations were isolated from organoids based on a marker for infection and transcriptomes were defined.

    An Approach to Measuring Protein Turnover in Human Induced Pluripotent Stem Cell Organoids by Mass Spectrometry

    The authors designed a workflow to reproducibly extract proteins from brain organoids, measure global turnover using mass spectrometry, and statistically investigate turnover differences between genotypes.

    Abstract

    deepOrganoid: A Brightfield Cell Viability Model for Screening Matrix-Embedded Organoids

    Investigators described the development and implementation of a regressive deep learning model trained on brightfield images of patient-derived organoids and use the terminal viability readout as training labels.
