Southern elephant seals develop hair follicles and skin layers before birth, with moulting starting a week after birth and finishing in three weeks.

Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.

Fat-derived stem cells can help protect and repair skin stem cells from aging caused by UV light.

Mouse stem cells from hair follicles can improve wound healing and reduce scarring.

Bone marrow-derived stem cells improved healing and reduced scarring in second-degree burns in rats.

Lambs fed a liquid diet showed abnormal wool and skin, which improved with more B-vitamins, suggesting a link to B-vitamin deficiency.

Green tea component EGCG helps keep rat skin grafts viable longer.

Collagen-enhanced mesenchymal stem cells significantly improve skin wound healing.

The three adipokines—leptin, adiponectin, and resistin—are present in various cells of normal dog skin.

The Megsin-Cre transgene is a new tool for genetic manipulation in the skin and upper digestive tract.

3D bioprinting shows promise for creating skin substitutes, but standardized methods are needed for clinical use.

The document concludes that the skin is a complex organ providing protection, sensation, and healing, with challenges in treating conditions like itchiness.
