Melanocytes are destroyed by factors needed for melanin production, causing vitiligo and gray hair.

Special gut cells help stem cells move to and fix injured areas by activating a specific signaling pathway.

Wound healing involves three phases and various cells and factors, with scars typically forming in adults. Chronic wounds can occur due to various issues, and abnormal scarring can lead to hypertrophic or keloid scars. Emerging research areas include the role of proteins, microRNAs, macrophage manipulation, and stem cell treatment.

Alopecia areata affects hair follicle structure, even in non-balding areas.

Micro-injury can help regrow hair and repigment vitiligo by activating specific cells.

Deep dermal tissue dislocation injury in pigs leads to thicker fibrotic tissue and increased type III collagen, affecting skin repair.

TGF-β1 and TNF-α contribute to lung damage after radiation.

The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

SOX2 helps reduce wound size and pressure ulcer formation by suppressing oxidative stress and increasing antioxidant activity in mice.

Blocking DPP4 can potentially speed up hair growth and regeneration, especially after injury or in cases of hair loss.

Hair follicle stem cells can become motor neurons and reduce muscle loss after nerve injury.
