Fetal wound healing: an overview

The ability of fetal tissues to heal without scarring has prompted extensive research into the biochemical and molecular differences between fetal and postnatal wound healing. A thorough understanding of the basic mechanisms of fetal wound repair may to lead to approaches to correct or prevent the clinical problems encountered in abnormal adult wound healing and fetal surgery. This article contrasts the normal healing response in adults with fetal repair in animal models, highlighting investigations of extracellular matrix expression, cytokine profiles, and cellular dynamics.
