Older mice have stiffer skin with less elasticity due to changes in collagen and skin structure, affecting aging and hair loss.

Estrogen is important for keeping adult mouse nipple skin healthy by controlling certain cell signals.

Blocking β-catenin in skin cells improves hair growth during wound healing.

Retinoic acid-binding proteins in skin are regulated by β-catenin and Notch signalling.

Epidermal stem cells have various roles in skin beyond just maintenance, including forming specialized structures and aiding in skin repair and regeneration.

Bird foot scales develop differently and can repair but not fully regenerate due to the lack of specialized stem cell areas.

Activating a protein called β-catenin in adult skin can make it behave like young skin, potentially helping with skin aging and hair loss.

Skin fat has important roles in hair growth, skin repair, immune defense, and aging, and could be targeted for skin and hair treatments.

Hormones and stretching both needed for nipple area skin growth in mice.

Smad4 is important for healthy hair follicles because it helps produce a protein needed for hair to stick together and grow.

Horse skin stem cells combined with platelet-rich plasma improve skin healing.

Hair growth can be stimulated by combining certain skin cells, which can rejuvenate old cells and cause them to specialize in hair follicle creation.

The conclusion is that the cornea has two types of stem cells, with Lrig1+ cells being key for renewal in aging corneas, independent of CD44.

Mice with too much Claudin-6 have skin barrier problems and abnormal hair growth.

The spiny mouse can regenerate its skin without scarring, which could help us learn how to heal human skin better.

The document concludes that understanding how the skin's immune system and inflammation work is complex and requires more research to improve treatments for skin diseases.

Estrogen replacement can improve skin health in menopausal women but doesn't reverse sun damage or prevent hair loss.

The document concludes that adult mammalian skin contains multiple stem cell populations with specific markers, important for understanding skin regeneration and related conditions.

Knowing how skin works and its diseases helps doctors diagnose and treat skin conditions better.

The document explains different types of skin lesions and their characteristics, causes, and related conditions.

The document concludes that mouse models are helpful but have limitations for skin wound healing research, and suggests using larger animals and genetically modified mice for better human application.
