    Force-FAK Signaling Coupling at Individual Focal Adhesions Coordinates Mechanosensing and Microtissue Repair

    Using cells adhering to deformable micropillar arrays, the authors demonstrated that traction force and FAK localization as well as traction force and Y397-FAK phosphorylation were linearly coupled at individual focal adhesions on stiff, but not soft, substrates.

    Low Magnitude Vibration Alleviates Age-Related Bone Loss by Inhibiting Cell Senescence of Osteogenic Cells in Naturally Senescent Rats

    Researchers found osteogenic cells from aged rats all exhibited senescence changes, with the most pronounced senescence changes in osteocytes. Meanwhile, the proliferative capacity and functional activity of osteogenic cells from aged rats were suppressed.
