    The giant staphylococcal protein Embp facilitates colonization of surfaces through Velcro-like attachment to fibrillated fibronectin

    Nasar Khan, Hüsnü Aslan ... Rikke Louise Meyer
    Fibronectin can shift from a globular to fibrillated form when adsorbing to implant surfaces, and this shift makes it accessible to attachment by Staphylococcus epidermidis, which is the leading cause of implant-associated infections.

    Dynamic fibronectin assembly and remodeling by leader neural crest cells prevents jamming in collective cell migration

    William Duncan Martinson, Rebecca McLennan ... Philip K Maini
    Data-driven mathematical modeling suggests that leading neural crest cells in a moving stream can robustly communicate with trailing cells by remodeling their extracellular matrix, thereby enabling long-distance collective migration.

    Fibronectin is a smart adhesive that both influences and responds to the mechanics of early spinal column development

    Emilie Guillon, Dipjyoti Das ... Scott Holley
    A fibronectin matrix constantly remodels to the area of highest mechanical stress, and the resulting fibronectin-mediated inter-tissue adhesion impedes neural tube convergence.

    Cardiac differentiation of human pluripotent stem cells using defined extracellular matrix proteins reveals essential role of fibronectin

    Jianhua Zhang, Zachery R Gregorich ... Timothy J Kamp
    Investigation of defined extracellular matrix proteins in differentiation of human pluripotent stem cells to cardiomyocytes reveals fibronectin, in addition to soluble factors, is required for cardiogenesis.

    The fibronectin synergy site re-enforces cell adhesion and mediates a crosstalk between integrin classes

    Maria Benito-Jardón, Sarah Klapproth ... Mercedes Costell
    The fibronectin synergy site is only required in vivo when forces exceed or αvβ3 integrin levels fall below certain thresholds.

    Kindlin-2 cooperates with talin to activate integrins and induces cell spreading by directly binding paxillin

    Marina Theodosiou, Moritz Widmaier ... Reinhard Fässler
    Kindlin-2 co-operates with talin to activate fibronectin-binding integrins on fibroblasts and subsequently induces cell spreading by recruiting paxillin to small, peripheral nascent adhesions.

    PI3K/Akt1 signalling specifies foregut precursors by generating regionalized extra-cellular matrix

    S Nahuel Villegas, Michaela Rothová ... Joshua M Brickman
    A signalling cascade involving PI3K/Akt1 remodels the extra-cellular matrix to achieve atypical cellular responses and control cell fate specification within the embryonic endoderm.

    Identification of specific Tie2 cleavage sites and therapeutic modulation in experimental sepsis

    Temitayo O Idowu, Valerie Etzrodt ... Sascha David
    Matrix metalloprotease (MMP)-14 cleaves Tie2 at three distinct sites within the fibronectin type-III (FN3) domain and its pharmacological blockade inhibits Tie2 pathological shedding to exert barrier protective effects.

    Matrix metalloproteinase 14 is required for fibrous tissue expansion

    Susan H Taylor, Ching-Yan Chloé Yeung ... Karl E Kadler
    The membrane type I-matrix metalloproteinase is essential for the release of collagen fibrils from plasma membrane fibripositors, which is required for the transition from embryonic to postnatal tendon development.

    Regulation of posterior body and epidermal morphogenesis in zebrafish by localized Yap1 and Wwtr1

    David Kimelman, Natalie L Smith ... Didier YR Stainier
    Analysis of a double mutant in the Hippo pathway transcription factors Yap1 and Wwtr1 reveals novel roles for these factors in posterior body formation and epidermal morphogenesis in the vertebrate embryo.
