    Heterogeneity of proteome dynamics between connective tissue phases of adult tendon

    Howard Choi et al.
    Metabolic labelling reveals complex proteome dynamics in tendon, with faster turnover of proteins in the glycoprotein-rich interfascicular matrix compared to the collagen-rich fascicular matrix.

    Measuring NDC80 binding reveals the molecular basis of tension-dependent kinetochore-microtubule attachments

    Tae Yeon Yoo et al.
    Quantitative experiments and theory show that the tension-dependent regulation of NDC80 binding to kinetochore microtubules arises from a combination of the changing Aurora B concentration at NDC80 and the nonlinearity of Aurora B autoactivation.

    Tunable molecular tension sensors reveal extension-based control of vinculin loading

    Andrew S LaCroix et al.
    A quantitative understanding of molecular tension sensor function enables the production of unique sensors with desired mechanical properties as well as the ability to distinguish between protein force and protein deformation in mechanosensitive processes.

    Tgfβ signaling is required for tenocyte recruitment and functional neonatal tendon regeneration

    Deepak A Kaji et al.
    TGFß signaling regulates migration of tenogenic cells from Scx- and non-Scx lineages and is required for functional regeneration after neonatal tendon injury.

    Tgfβ signaling is critical for maintenance of the tendon cell fate

    Guak-Kim Tan et al.
    Conditional deletion of TGFβ signaling results in tenocyte dedifferentiation in vivo demonstrating a key role for TGFβ signaling in the maintenance of the tendon cell fate.

    A distinct transition from cell growth to physiological homeostasis in the tendon

    Mor Grinstein et al.
    Mitotic labeling defines a change in cell division kinetics from growth to homeostasis and identifies slowly cycling cells in the adult tendon.

    Cell non-autonomous functions of S100a4 drive fibrotic tendon healing

    Jessica E Ackerman et al.
    Inhibition of S100a4 represents a novel anti-fibrotic target to improve tendon healing.

    Osteocalcin expressing cells from tendon sheaths in mice contribute to tendon repair by activating Hedgehog signaling

    Yi Wang et al.
    Cells in tendon sheaths, considered to be extrinsic tissues of tendon, possess stem or progenitor cell properties that are involved in tendon repair by activating the Hh-TGFb/Smad3 axis.

    Axon tension regulates fasciculation/defasciculation through the control of axon shaft zippering

    Daniel Šmít et al.
    Competition between adhesive and tensile forces regulates axon fasciculation, thus introducing a new role of mechanical tension in the development of neural networks.
