3D bioprinting improves wound healing by precisely creating scaffolds with living cells and biomaterials, but faces challenges like resolution and speed.

Notch signaling disruptions can cause various skin diseases.

Genetic changes in mice help understand skin and hair disorders, aiding treatment development for acne and hair loss.

Wool follicle cells are more complex than previously thought.

New treatments for ichthyosis, like protein replacement and gene therapy, show promise and may become standard care.

The study created hair-bearing skin models that lack a key protein for skin layer attachment, limiting their use for certain skin disease research.

The study identified key genes that regulate the growth cycle of cashmere in goats, which could help improve breeding strategies.

The genes KRT25 and SP6 affect curly hair in horses, with KRT25 also causing hair loss. If both genes are mutated, the horse gets curly hair and hair loss. KRT25 can hide the effect of SP6.

Sheep and goat hair fibers are complex due to keratin-associated proteins, which are important for fiber properties and growth.

MicroRNAs are important for hair growth regulation, with Dicer being crucial and Tarbp2 less significant.

Kangfuxin (KFX) extract speeds up wound healing and improves skin regeneration.

Older mice have stiffer skin with less elasticity due to changes in collagen and skin structure, affecting aging and hair loss.

Intermediate filaments are crucial for cell differentiation and stem cell function.

Transplanted hair follicle stem cells improved brain function and reduced damage after a stroke in rats.

Extracts from Alnus sibirica and oregonin may help with hair growth and prevent hair loss.

Alopecia Areata causes significant structural and compositional changes in hair.

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.

Menopause causes significant changes in the vaginal introitus, but less so in the labia majora, which may lead to symptoms of vaginal atrophy.

I'm sorry, but I can't provide a summary without the content of the document.

Cell-based models help test if cosmetic ingredients really work for hair growth and skin health.

RSPO1 mutations in certain patients lead to skin cells that don't develop properly and are more likely to become invasive, increasing the risk of skin cancer.

Nanomaterials can improve hair care products and treatments, including hair loss and alopecia, by enhancing stability and safety, and allowing controlled release of compounds, but their safety in cosmetics needs more understanding.

Wnt/β-catenin signaling is important for keeping skin cell attachment structures stable.

Stress may contribute to hair loss in alopecia areata by affecting immune responses and cell death in hair follicles.

Camellia japonica extract may improve scalp health and promote hair growth.

Nanofiber scaffolds help wounds heal by delivering drugs directly to the injury site.

Some hair protein genes evolved early and were adapted for use in hair follicles.

Sex and sex hormones can affect brain inflammation in Parkinson's disease, with male mice being more affected and female mice showing a protective effect.

AIRE deficiency causes hair loss similar to alopecia areata in mice.
