Keloid research: current status and future directions

Recent research indicates that the formation/growth of keloids and hypertrophic scars associate clearly with genetic, epigenetic, systemic and local risk factors, particularly skin tension around scars. Further research into scar-related genetics, epigenetics and mechanobiology may reveal molecular, cellular or tissue-level targets that could lead to the development of more effective prophylactic and therapeutic strategies for wounds/scars in the future.
