Dermatoscopy and videodermatoscopy are useful for diagnosing and monitoring various skin, hair, and nail conditions.

Superficial granulomatous pyoderma is a unique, mild form of skin disease that often heals without strong medication and responds well to milder treatments.

Cathepsin L is essential for normal hair growth and development.

The article concludes that the wool follicle is a valuable model for studying tissue interactions and has potential for genetic improvements in wool production.

Wnt and Notch signaling help wound healing by promoting cell growth and regulating cell differentiation.

The sebaceous gland has more roles than just producing sebum and contributing to acne, and new research could lead to better skin disease treatments.

Keratin 15 is not a reliable sole marker for identifying epidermal stem cells because it's found in various cell types.

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

Mesenchymal stem cells show potential for skin healing and anti-aging, but more research is needed for safe use, especially regarding stem cells from induced pluripotent sources.

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

Tiny needles with valproic acid can effectively regrow hair.

Advanced nanocarrier and microneedle drug delivery methods are more effective, safer, and less invasive for treating skin diseases.

Wnt signaling is crucial for skin wound healing and reducing scars.

Cyclosporin A helps mice grow hair by blocking a specific protein activity in skin cells.
