International audience. The skin is the first protective barrier of our body. Wound healing is therefore an essential mechanism. However, this phenomenon can be impaired when wounds are too large or chronic, for example, in diabetes. Interestingly, adult skin heals with scars, whereas foetuses present scarless regeneration. The objective of this review is to highlight the difference in healing pathways between foetal and adult skin and to present the recent therapeutic strategies envisaged using foetal properties in the clinic. The main features that distinguish foetal wound healing from adult wound healing are less tissue inflammation, faster reepithelialisation, and less contraction of the neodermis, allowing foetal tissues to regenerate. Recently, new therapies in regenerative medicine have been introduced using these foetal properties. For the first time, our team has developed CICAFAST, an innovative dressing composed of foetal keratinocytes and fibroblasts, which has been tested on a skin graft donor site in a clinical Phase 1/2 trial.
