GlossaryFetal Skin

skin of a developing fetus with scarless healing properties

Fetal skin, also known as fetal dermis or fetal epidermis, refers to the skin of a developing fetus. It is characterized by its remarkable ability to heal without scarring, a property that diminishes after birth. This unique regenerative capability is of significant interest in medical research, particularly for developing advanced wound healing therapies and understanding skin development.
