Skin and hair can regenerate after injury due to changes in gene activity, with potential links to how cancer spreads. Future research should focus on how new hair follicles form and the processes that trigger their creation.

The engineered skin substitute helped grow skin with hair on mice.

Bioprinting could improve wound healing but needs more development to match real skin.

Different types of stem cells and their environments are key to skin repair and maintenance.

Damage to skin releases dsRNA, which activates TLR3 and helps in skin and hair follicle regeneration.

Notch1 helps skin heal by attracting specific immune cells.

Activin helps skin growth and healing mainly through stromal cells and affects keratinocytes based on its amount.
