Function preservation1

  • Clearing early senescent cells may disrupt bone repair by erasing spatial differentiation cues

    Where this hypothesis actsEarly bone repair, where correctly positioned senescent cells may supply or position morphogen sources

    What is proposedPreserve correctly positioned early senescent repair cells

    With whatNot stated in the record

    HowSelectively preserve early cells according to their spatial position; the preservation technique is not stated

    Possible resultPossible protection of positional information and formation of a mechanically continuous bone bridge

Senolysis3

  • A self-supporting matrix may determine when senescent cell removal preserves skin strength

    Where this hypothesis actsTransient senescence during early skin wound healing

    What is proposedPreserve cells until the matrix forms a stable load-bearing network, then remove them

    With whatInstrument or assay

    HowTime removal by whether the matrix maintains load transmission during brief suppression of active cellular contraction

    Possible resultPossible improvement in later skin strength compared with immediate cell removal

  • Removing senescent cells may renew damage by removing their mechanical protection

    Where this hypothesis actsChronically senescent cells in aged skin

    What is proposedRemove harmful senescent cells while restoring their mechanical protection

    With whatNot stated in the record

    HowNot stated in the record

    Possible resultPossible reduction in SPV_1 when cell removal is combined with restored load dissipation

  • Organelle upkeep, secretion control and cell removal may independently extend life

    Where this hypothesis actsSenescent cells that impair tissue repair even when their secretion is suppressed

    What is proposedRemove senescent cells that impair tissue repair

    With whatNot stated in the record

    HowUse antigen-dependent cytotoxicity requiring antigen presentation by the senescent cells

    Possible resultPossible lasting functional benefits across multiple systems and increased lifespan
