    Generation
    of Human Striatal Organoids and Cortico-Striatal Assembloids from Human Pluripotent Stem Cells

    Researchers developed a method to convert human pluripotent stem cells into region-specific brain organoids that resemble the developing human striatum and include electrically active medium spiny neurons.

    A
    Comprehensive Library of Human Transcription Factors for Cell Fate Engineering

    Scientists demonstrated orthogonal programming by including oligodendrocyte-inducible hPSCs with unmodified hPSCs to generate cerebral organoids, which expedited in situ myelination.

    Abstract

    Establishment
    of Human Fetal Hepatocyte Organoids and CRISPR–Cas9-Based Gene Knockin and Knockout in Organoid Cultures from Human Liver

    Investigators established culture conditions that facilitated long-term expansion of human fetal hepatocytes as organoids.

    Abstract

    Antigen Retrieval and Clearing for Whole-Organ Immunofluorescence by FLASH

    FLASH utilizes non-degradative epitope recovery and membrane solubilization to enable the detection of a multitude of membranous, cytoplasmic and nuclear antigens in whole mouse organs and embryos, human biopsies, organoids and Drosophila.

    Abstract

    Gap
    Junctions Amplify Spatial Variations in Cell Volume in Proliferating Tumor Spheroids

    Researchers identified that ion flow through gap junctions promoted peripheral cell swelling in loaded breast cancer model.

    The
    Microfluidic Environment Reveals a Hidden Role of Self-Organizing Extracellular Matrix in Hepatic Commitment and Organoid Formation of hiPSCs

    Hepatic progenitor cells either derived in microfluidics or exposed to exogenous ECM stimuli showed a significantly higher potential of forming hepatic organoids that could be rapidly expanded for several passages and further differentiated into functional hepatocytes.

    RON Signaling Promotes Therapeutic Resistance in ESR1 Mutant Breast Cancer

    Scientists performed a proteomic kinome analysis in ESR1 Y537S mutant cells to identify hyperactivated kinases in ESR1 mutant cells. They validated Recepteur d’Origine Nantais (RON) and PI3K hyperactivity through phospho-immunoblot analysis, organoid growth assays, and in an in vivo patient-derived xenograft metastatic model.

    Super
    Resolution Microscopy and Deep Learning Identify Zika Virus Reorganization of the Endoplasmic Reticulum

    Using 3D super resolution microscopy, ZIKV infection was shown to induce the formation of dense tubular matrices associated with viral replication in the central endoplasmic reticulum.

    A
    Proof of Concept ‘Phase Zero’ Study of Neurodevelopment Using Brain Organoid Models with Vis/Near-Infrared Spectroscopy and Electrophysiology

    Scientists present the feasibility of a multimodal approach, combining electrophysiology and broadband Vis–NIR spectroscopy, to monitor neurodevelopment in brain organoid models that could complement traditional drug design approaches to test clinically meaningful hypotheses.

    Regenerative
    Intestinal Stem Cells Induced by Acute and Chronic Injury: The Saving Grace of the Epithelium?

    Researchers cover the latest research on damage-associated regenerative ISCs and epigenetic factors that determine intestinal stem cell (ISC) fate, as well as provide opinions on future studies that need to be undertaken to understand the repercussions of the emergence of these cells, their contribution to relapses in inflammatory bowel disease, and their potential use in therapeutics for chronic intestinal diseases.
