Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

Foxp3 is crucial for regulatory T cell function, and targeting these cells may help treat immune disorders.

Cepharanthine is a well-tolerated drug with multiple medical uses, including anti-inflammatory and anti-cancer properties.

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

Understanding how cells die in the skin is important for treating skin diseases and preventing hair loss.

New topical antifungals and delivery systems are improving treatment for fungal skin infections, but patient education and prevention are key.

Hair, teeth, and mammary glands develop similarly at first but use different genes later.

Too much Smad7 can cause serious changes in skin tissues, including problems with hair growth, thymus shrinkage, and eye development issues.
