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

The document concludes that the human keratin gene cluster is complex, with a need for updated naming to reflect over 50 functional genes important for hair and skin biology.

Doctors should use a detailed patient history and physical exam to diagnose joint pain, and consult a rheumatologist early for suspected autoimmune diseases.

Electrospun scaffolds can improve healing in diabetic wounds.

Hard skin features like scales, feathers, and hair evolved through specific protein changes in different animal groups.

The skin systems of jawed vertebrates evolved diverse appendages like hair and scales from a common structure over 420 million years ago.

Cows moving from tie-stall to free-stall housing had more heel problems, less joint lesions, and higher stress levels.

Mice with more Flightless I protein grew back their claws better after amputation.

The conclusion is that teeth, hair, and claws have similar stem cell niches, which are important for growth and repair, and more research is needed on their regulation and potential markers.

Cows moving from tie-stalls to free-stalls had fewer leg injuries but more stress and heel horn erosions.

Modulating BMP activity changes the number, size, shape, and type of ectodermal organs.

Mice without certain skin proteins had abnormal skin and hair development.

Helianthus annuus and Martynia annua seed oils significantly promote hair growth.

A new skin disease in four Labrador retrievers responded well to immunosuppressive treatment.

Different ectodermal organs like hair and feathers regenerate differently, with specific stem cells and signals involved in their growth and response to the environment.

The kitten's skin infection was cured with medication in three weeks.

Hair and nail cells share similar proteins, indicating a common differentiation pathway.

Animals that change color with the seasons mainly do so in response to daylight changes, but climate change is causing camouflage problems that may require evolutionary changes.

Follistatin helps hair growth and cycling, while activin prevents it.

Skin problems can be caused or worsened by physical forces and pressure on the skin.

Photothermal hydrogels are promising for infection control and tissue repair, and combining them with other treatments could improve results and lower costs.

The conclusion is that a new biopsy technique and humidity chamber help study skin mites better and suggest mite overpopulation may cause skin diseases.

Cysteine-rich keratins evolved independently in mammals, reptiles, and birds for hard skin structures like hair, claws, and feathers.

Subcutaneous contraceptives can cause side effects like menstrual changes, headaches, weight gain, and pain at the implant site.

Hair in mammals likely evolved from glandular structures, not scales.

High levels of the protein Flightless I worsen ulcerative colitis symptoms in mice.

The document emphasizes the importance of correctly identifying and classifying genetic hair disorders to help diagnose related health conditions.

Keratin 33A is a key protein in goat winter coats, especially in high-producing breeds.

Angora goat hair grows faster and produces more protein than cashmere goat hair, and certain hormones and nutrients positively affect hair growth and protein synthesis.
