Advanced human skin models improve drug development and could replace animal testing.

Melanocyte development from neural crest cells is complex and influenced by many factors, and better understanding could help treat skin disorders.

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

Understanding how hair follicle stem cells work can help find new ways to prevent hair loss and promote hair growth.

The extracellular matrix is crucial for controlling skin stem cell behavior and health.

Wnt, Eda, and Shh pathways are crucial for different stages of sweat gland development in mice.

The study found that certain microRNAs are higher in the cells and lower in the fluid of women with a specific type of polycystic ovary syndrome, and one microRNA could potentially help diagnose the condition.

The document concludes that mouse models are crucial for studying hair biology and that all mutant mice may have hair growth abnormalities that require detailed analysis to identify.
