Skin injuries normally lead to scars, but fetal wounds heal without them. This review explores the molecular basis of scar formation versus scarless healing, aiming to replicate fetal healing in adults.

Area of Science:

  • Regenerative medicine
  • Wound healing biology
  • Dermatology

Background:

  • Cutaneous injuries trigger a spectrum of wound repair responses.
  • These responses range from excessive scarring (keloids) to scarless healing, observed in fetal wounds.
  • Understanding the molecular mechanisms underlying these diverse outcomes is crucial.

Purpose of the Study:

  • To review the molecular biology of scar formation and scarless healing.
  • To elucidate the mechanisms driving different clinical wound healing phenotypes.
  • To discuss future strategies for achieving scarless wound healing in adults.

Main Methods:

  • Literature review of molecular biology and wound repair mechanisms.
  • Analysis of studies on fetal wound healing.

  • Exploration of potential therapeutic modalities.

    • Main Results:

    • Wound healing exists on a continuum from hypertrophic scarring to regeneration.
    • Fetal wound healing represents a model for scarless repair.
    • Specific molecular pathways dictate the clinical outcome of cutaneous injury.

    Conclusions:

    • Scar formation is a complex biological process influenced by molecular signaling.
    • Fetal healing mechanisms offer insights into achieving scarless repair in adults.
    • Future research may lead to therapies that promote regeneration over scarring.
