Aging mice have slower hair regeneration due to changes in signal balance, but the environment, not stem cell loss, controls this, suggesting treatments could focus on environmental factors.

Mice lacking a key DNA methylation enzyme in skin cells have a lower chance of activating stem cells necessary for hair growth, leading to progressive hair loss.

Wnt signaling is crucial for skin and hair development and its disruption can cause skin tumors.

Keratin proteins are crucial for healthy skin, but mutations can cause skin disorders with no effective treatments yet.

The study identified and characterized new keratin genes linked to hair follicles and epithelial tissues.

Acne is caused by genetics, diet, hormones, and bacteria, with treatments not yet curative.

Different scaffold patterns improve wound healing and immune response in mouse skin, with aligned patterns being particularly effective.

Anti-acne medications may work by reducing the activity of a protein involved in acne development.

Prolactin affects the production of different keratins in human hair, which could lead to new treatments for skin and hair disorders.
