Different genes are active in dogs' hair growth and skin, similar to humans, which helps understand dog skin and hair diseases and can relate to human conditions.

Overactive Wnt signaling in mouse skin stem cells causes acne-like cysts and shrinking oil glands, which some treatments can partially fix.

Regulating cell death in hair follicles can help prevent hair loss and promote hair growth.

Hairlessness in mammals is due to complex genetic changes in both genes and regulatory regions.

Skin can heal wounds without hair follicle stem cells, but it takes a bit longer.

Understanding hair follicles through various models can help develop new treatments for hair disorders.

Special particles from skin cells can promote hair growth by activating a specific growth signal.

A two-step method was created in 2015 to make more cells that help with hair growth, but they need to be combined with other cells for 4 days to actually form new hair.

iPSCs can help treat genetic skin disorders by creating healthy skin cells from a small biopsy.

Enzymes called PADIs play a key role in hair growth and loss.

Deleting the EDAR gene in Cashmere goats affects genes and proteins related to hair growth.

Host cells are crucial for the maturation of reconstructed hair follicles.

The Notch signaling pathway is important for hair follicle development and could help create treatments for hair disorders.

Apoptosis is essential for human skin development and forming a functional epidermis.

Sex hormones, especially estradiol, can change chicken feather shapes and colors.

Melatonin given to pregnant rabbits improved their babies' fur quality.

The Foxn1(-/-) nude mouse shows disrupted and expanded skin stem cell areas due to high Lhx2 levels.

Good feather growth in poultry needs the right balance of proteins, amino acids, minerals, and vitamins.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

Nerves are crucial for the regeneration of various body parts in many animals.

Mammals might fail to regenerate not because they lack the right cells, but because of how cells respond to their surroundings, and changing this environment could enhance regeneration.

Hair growth and development are controlled by specific signaling pathways.

Hair follicle stem cells are controlled by their surrounding environment.

Dermal papilla cells can help regrow hair and are promising for hair loss treatments.

IGF-1 may affect hair growth and loss, but more research is needed to confirm effective and safe treatments.

Skin stem cells are crucial for maintaining and repairing the skin and hair, using a complex mix of signals to do so.

Hair growth can be induced by certain cells found at the base of hair follicles, and these cells may also influence hair development and regeneration.

The cause and importance of misplaced oil glands in the hair follicle are not well understood.

Herbal treatments can help with hair problems, but more research is needed.

Smad-4 and Smad-7 are key in hair follicle development, with other Smads being less important.
