SEM images of fetal wound healing. (a) E13 wound, (b) E14 wound. Scale bar = 100 µm. (c) Difference in epidermal–dermal interactions at the wound margin between E13 and E14. In E13 wounds, the epidermis and dermis remained in position, the wound closed, and epidermal–dermal interactions were always observed. In E14 wounds, epidermal–fascial interactions were observed, even if only temporarily. Scale bar = 20 µm.
