    Non-canonical Wnt signalling modulates the endothelial shear stress flow sensor in vascular remodelling

    Claudio A Franco, Martin L Jones ... Holger Gerhardt
    A threshold level of blood flow initiates developmental blood vessel regression; this threshold can be regulated by non-canonical Wnt ligands.

    Non-canonical Wnt signaling regulates junctional mechanocoupling during angiogenic collective cell migration

    Joana R Carvalho, Isabela C Fortunato ... Claudio A Franco
    Analysis of axial polarity distributions shows that Wnt5a regulates collective cell migration in vivo by stabilizing vinculin at adherens junctions and fine-tuning mechanocoupling between neighbouring cells.

    High-resolution imaging of the osteogenic and angiogenic interface at the site of murine cranial bone defect repair via multiphoton microscopy

    Kevin Schilling, Yuankun Zhai ... Xinping Zhang
    High-resolution multiphoton microscopy reveals coupling of blood vessel subtype with expanding osteoblasts at the bone regeneration interface, further highlighting the heterogeneity of oxygen microenvironment and its impact on cellular energy metabolism of bone and vessel forming cells.

    Correlated magnetic resonance imaging and ultramicroscopy (MR-UM) is a tool kit to assess the dynamics of glioma angiogenesis

    Michael O Breckwoldt, Julia Bode ... Björn Tews
    Correlated magnetic resonance imaging and ultramicroscopy resolves macro- and microvasculature in glioma models and allows treatment monitoring of antiangiogenic therapy.

    Synchronization of endothelial Dll4-Notch dynamics switch blood vessels from branching to expansion

    Benedetta Ubezio, Raquel Agudo Blanco ... Holger Gerhardt
    Increasing levels of the growth factor Vegfa disrupt blood vessel branching morphogenesis and drive diameter increase by synchronizing Notch signalling fluctuations between endothelial cells.

    Hematopoietic stem and progenitor cells regulate the regeneration of their niche by secreting Angiopoietin-1

    Bo O Zhou, Lei Ding, Sean J Morrison
    Normal hematopoietic stem and progenitor cells slow the regeneration of their niche after injury to minimize leakage from the niche vasculature.

    Mouse retinal cell behaviour in space and time using light sheet fluorescence microscopy

    Claudia Prahst, Parham Ashrafzadeh ... Katie Bentley
    Improved 3D and 4D imaging of neurovascular processes across scales reveals new insights into eye disease mouse models and shows retinal vessels are significantly distorted using standard flat-mount confocal imaging.

    CD31 signaling promotes the detachment at the uropod of extravasating neutrophils allowing their migration to sites of inflammation

    Francesco Andreata, Marc Clément ... Giuseppina Caligiuri
    CD31 plays a pivotal role in neutrophil migration to inflamed sites by localizing to the uropod and promoting effective actin/integrin polarization and detachment, shedding light on the molecular mechanisms underlying extravasation and inflammation response.

    Spatiotemporal dynamics and heterogeneity of renal lymphatics in mammalian development and cystic kidney disease

    Daniyal J Jafree, Dale Moulding ... David A Long
    Three-dimensional imaging was used to identify structural and quantitative features of developing lymphatics in the kidneys of mice, humans and in a genetic mouse model of polycystic kidney disease.

    A novel L1CAM isoform with angiogenic activity generated by NOVA2-mediated alternative splicing

    Francesca Angiolini, Elisa Belloni ... Claudia Ghigna
    Endothelial cells express a soluble isoform of the L1CAM cell adhesion molecule that is generated by the splicing factor NOVA2 and induces angiogenesis, with relevant implications for ovarian cancer vascularization.
