Inhibition1

  • A final wave of extracellular signal-regulated kinase activity may permit epithelial maturation

    Where this hypothesis actsRegenerating epithelium under controlled local hydration, before complete closure

    What is proposedEnd further activity waves after the final coordinated wave has crossed the covered area

    With whatChange of environment or regimen

    HowUse light-controlled signalling constructs to control pulse sequences and fluorescent reporters to track ERK waves and time stimulus withdrawal

    Possible resultPossible earlier functional readiness and restored friction tolerance

Activation1

  • Hyaluronan fragmentation may blur damage timing signals and delay skin matrix maturation

    Where this hypothesis actsDermal fibroblasts exposed to introduced hyaluronan and repeated injury

    What is proposedRestore activation sequences aligned with actual injury episodes

    With whatNot stated in the record

    HowControlled reproduction of ERK activity sequences in an organotypic human dermal fibroblast model, comparing injury-aligned, shifted and shuffled sequences

    Possible resultPossible recovery of cellular discrimination between injury and recovery, shortening time to mechanical readiness
