TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

Oxidative stress contributes to hair graying and loss as we age.

The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.

Animals that change color with the seasons mainly do so in response to daylight changes, but climate change is causing camouflage problems that may require evolutionary changes.

Mice without the Sept4/ARTS gene heal wounds better due to more stem cells that don't die easily.

Nuclear hormone receptors play a significant role in skin wound healing and could lead to better treatment methods.

The document concludes that the skin's immune system is complex, involving interactions with hair follicles, nerves, and microbes, and can protect or cause disease, offering targets for new treatments.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.
