Inhibition1

  • Clearing early senescent cells may prevent fracture union by releasing mechanical prestress

    Where this hypothesis actsVerified senescent cells in an instrumented early-callus culture

    What is proposedReversibly inhibit myosin in senescent cells to test its mechanical contribution

    With whatNot stated in the record

    HowUse reversible, lineage-restricted inhibition while preserving cell viability, extracellular matrix content and secretory output

    Possible resultExpected immediate fall in callus stiffness if senescent-cell traction provides protective prestress

Activation1

  • Surviving replacement muscle stays weak because too few myosin motors become active

    Where this hypothesis actsSurviving replacement fibers with persistent motor inhibition after inactivity

    What is proposedIncrease the availability of myosin motors for force-producing cycles

    With whatNot stated in the record

    HowManipulate myosin regulatory state, with controls for direct changes in calcium sensitivity

    Possible resultPossible restoration of force and stabilization of SPV_9 without tissue renewal
