Mouflon rams mature gradually with changes in body, horns, and hormones linked to age and seasons, reaching full sexual maturity well after puberty.

Goat reproductive activity and coat growth are affected by light and temperature, with temperature altering prolactin levels and hair growth, but not melatonin or estrus onset.

Artificial skin development has challenges, but new materials and understanding cell behavior could improve tissue repair. Also, certain growth factors and hydrogel technology show promise for advanced skin replacement therapies.

One minoxidil-sensitive potassium channel exists in human hair follicles.

Adult mice can grow new hair from skin wounds.

Sex hormones affect hair and feather growth and may help manage alopecia and hormone-dependent cancers.

Androgens affect bone and fat cell development differently based on the cells' embryonic origin.

Male hormones cause different growth in identical human hair follicles due to their unique epigenetic characteristics.

The conclusion is that skin and hair patterns are formed by a mix of cell activities, molecular signals, and environmental factors.

Melatonin implants affect the growth and pattern of cashmere goat fleece depending on the time of year they are given.

Certain genes are more active during wound healing in axolotl and Acomys, which could help develop materials that improve human wound healing and regeneration.

Melatonin, usually known for sleep regulation, also has antioxidant properties that can protect skin, stimulate hair growth, and improve skin conditions, with topical application being more effective than oral use.

The review suggests that a special cell-derived treatment shows promise for various skin conditions and hair growth but needs more research for confirmation.

Extracellular vesicles, including exosomes from certain cells, can stimulate hair growth.

Melatonin helps hair grow by activating the RORα receptor in goats.

Prostaglandin D2 blocks new hair growth after skin injury through the Gpr44 receptor.

All-trans retinoic acid causes hair loss by increasing TGF-β2 in hair follicle cells.

The conclusion is that hair growth can be improved by activating hair cycles, changing the surrounding environment, healing wounds to create new hair follicles, and using stem cell technology.

Mice with enhanced regeneration abilities may help develop new regenerative medicine therapies.

Mice can regenerate ear tissue without the p53 protein.

Scientists made working hair follicles using stem cells, helping future hair loss treatments.

Stem cells have great potential for improving wound healing, but more research is needed to find the best types and ways to use them.

Androgens can both stimulate and cause hair loss, and understanding their effects is key to treating hair disorders.

Environmental factors like temperature and nutrition affect hair growth, with humans showing seasonal hair growth differences.

Androgens can cause hair growth in some areas but hair loss on the scalp.

Hair growth is influenced by hormones and goes through different phases; androgens can both promote and inhibit hair growth depending on the body area.

Androgens can both increase body hair and cause scalp hair loss.

The interdigital gland in crossbred sheep is similar to skin and has specialized structures for secretion.

Stem cells are crucial for wound healing and understanding their role could lead to new treatments, but more research is needed to answer unresolved questions.
