TGFα gene mutation in mice causes abnormal skin, wavy hair, curly whiskers, and sometimes eye inflammation.

The cornified cell envelope forms a protective barrier in skin and hair, using specific proteins and lipids to maintain effectiveness.

Cornification is how skin cells die to form the protective outer layer of skin, hair, and nails.

Small proline-rich proteins and trichohyalin help make epithelial tissues tougher and more flexible.

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

LGR5 helps maintain corneal cell characteristics and prevents unwanted changes by controlling specific cell signaling pathways.

Corneous beta-proteins evolved uniquely in reptiles and birds, forming scales, claws, beaks, and feathers.

A gene mutation in mice causes skin defects and early death.

Cat claws stay sharp by shedding their outer layer through microcracks formed during activities.

Different types of cells in the eye express specific keratins at various stages of development.

Clim proteins are essential for maintaining healthy corneas and hair follicles.

The enzyme DHHC13 is essential for healthy hair and skin, and its deficiency leads to hair loss and skin problems.

Insulin helps heal corneal wounds and nerves in diabetic mice by activating the Wnt signaling pathway.

Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.

Tight cornrow braids may cause hair loss.

Ichthyoses are genetic skin disorders that affect the skin's barrier function.

The document concludes that appearance can be significantly improved after one hair restoration correction procedure, but often multiple operations are needed for the best results.

The document suggests fixing bad hair transplants by removing large hair plugs and replacing them with smaller ones, considering the natural progression of hair loss, and emphasizing the need for ethical judgment in hair transplantation.

An 11-year-old girl with a rare skin disorder also had cornea issues and dry eye, needing careful management.

Cornu cervi pantotrichum pharmacopuncture solution helps mice grow hair by increasing hair follicle cell growth and a growth factor important for hair development.

The document suggests fixing common hair transplant issues by combining artistic principles with plug reduction, recycling, and additional micrograft transplantation, while also potentially using arnica to help with post-operative swelling.

The cornified envelope is crucial for skin's barrier function and involves key proteins and genetic factors.

People with plantar corns and calluses may have a higher chance of having metabolic syndrome.

Deleting the Hoxc13 gene in frogs shows its crucial role in developing skin structures similar to hair.

Early and aggressive treatment is crucial for preserving vision in infants with AEC syndrome.

Cornification is the process where living skin cells die to create a protective barrier, and problems with it can cause skin diseases.

The keratin network in mouse skin changes during cornification and affects the skin's protective barrier.

The conclusion is that the cornea has two types of stem cells, with Lrig1+ cells being key for renewal in aging corneas, independent of CD44.

Eyelash transplantation can cause eye damage and pain if not done carefully.

Adult hair follicle cells can create new hair follicles from corneal cells with the right support.
