    Transient external force induces phenotypic reversion of malignant epithelial structures via nitric oxide signaling

    Benjamin L Ricca, Gautham Venugopalan ... Daniel A Fletcher
    In a 3D culture model of breast epithelium, application of a short-timescale compression to single malignant cells promotes the long-timescale development of polarized, growth-arrested structures.

    Concerted action of neuroepithelial basal shrinkage and active epithelial migration ensures efficient optic cup morphogenesis

    Jaydeep Sidhaye, Caren Norden
    Cellular and tissue level analysis reveals how different cell behaviors involving dynamics of the basal domain cooperate in space and time to shape an epithelial organ.

    Paraxial mesoderm organoids model development of human somites

    Christoph Budjan, Shichen Liu ... Sahand Hormoz
    Human somites are formed in organoids from human pluripotent stem cells.

    Human embryonic lung epithelial tips are multipotent progenitors that can be expanded in vitro as long-term self-renewing organoids

    Marko Z Nikolić, Oriol Caritg ... Emma L Rawlins
    Improved characterisation of human embryonic lung development highlights human-mouse differences and facilitates the development of defined culture conditions for the expansion of self-renewing, multipotent human lung epithelial progenitor cells.

    Paracrine signalling between intestinal epithelial and tumour cells induces a regenerative programme

    Guillaume Jacquemin, Annabelle Wurmser ... Silvia Fre
    Studies of organoid morphogenesis, combined with proteomics and molecular profiling, identify the THBS1-YAP axis as a signalling mechanism that mediates paracrine communication between tumour cells and their wildtype epithelial neighbours.

    NFATc1 marks articular cartilage progenitors and negatively determines articular chondrocyte differentiation

    Fan Zhang, Yuanyuan Wang ... Xianpeng Ge
    NFATc1 is identified as a molecular marker of articular cartilage progenitor cells and a transcriptional repressor of chondrocyte differentiation, providing fundamental insights into the origin and differentiation mechanism of articular chondrocytes.

    Secretion of protein disulphide isomerase AGR2 confers tumorigenic properties

    Delphine Fessart, Charlotte Domblides ... Frederic Delom
    Epithelial tumors secrete the ER-resident AGR2 in the extracellular matrix to function as a novel essential microenvironmental regulator of epithelial tissue architecture, which leads to tumorigenicity.

    Mesenchyme instructs growth while epithelium directs branching in the mouse mammary gland

    Qiang Lan, Ewelina Trela ... Marja L Mikkola
    Live imaging, transcriptional profiling and mouse models demonstrated that the mesenchyme controls the growth pace but not the mode of branching of the mammary epithelium and unveiled a unique function for Igf1/Igfr1 in embryonic development mammary gland.

    Spinal neural tube formation and tail development in human embryos

    Chloe Santos, Abigail R Marshall ... Andrew J Copp
    Analysis of 108 human embryos aged 3–7 weeks reveals modes of primary and secondary neurulation, regulation of body elongation, somite formation rate, and common occurrence of a split neural tube.

    Combined lineage tracing and scRNA-seq reveals unexpected first heart field predominance of human iPSC differentiation

    Francisco X Galdos, Carissa Lee ... Sean M Wu
    TBX5 lineage tracing and high resolution single cell transcriptomics uncover the predominance of first heart field development during human-induced pluripotent stem cell cardiac differentiation.
