Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.

Mutations in keratin genes can cause skin and mucosa disorders.

Cultured skin cells can trigger hair growth and the amount of certain proteins they produce affects their ability to regenerate hair follicles.

The ID2 gene can help distinguish between sensitizers and irritants in skin cells.

The human scalp hair bulb contains different types of melanocytes with varying abilities to produce melanin.

Mouse and human keratin 16 can both form filaments, with differences likely due to the tail domain, not the helical domain.

Human stem cells were turned into cells similar to those that help grow hair and showed potential for hair follicle formation.

Cytokeratins 15 and 19 may help track vitiligo treatment progress.

Keratin 14 is uniquely found in a specific group of placental cells.

A chimeric keratin partially improved skin structure in mice lacking keratin 5, but didn't fully restore normal skin.

Keratin 17 is important for hair and nail structure and affects pachyonychia congenita symptoms.

The substance from human hair root cells can help maintain hair growth and make skin cells more capable of growing hair.

A unique skin cell similar to hair bulb melanocytes was identified, with better preservation using permanganate fixation.

Vertebrate skin evolved to be more specialized and complex, especially in land animals.

BKN-1 antibody targets specific keratin in basal cell epithelioma and normal skin basal cells.

K6 gene expression can be controlled and manipulated in mice for studying skin disorders.

Hair follicle cells can become fat and bone cells.

Beard hair medulla cells have a unique and varied keratin pattern.

Rat hair follicle stem cells can become corneal epithelium-like cells when exposed to rabbit corneal limbal stroma.

The K5 promoter controls gene expression in skin cells, with specific DNA segments crucial for targeting and regulation.

Keratin mutations cause skin diseases and could lead to new treatments.

Epidermal stem cells have various roles in skin beyond just maintenance, including forming specialized structures and aiding in skin repair and regeneration.

p63 may influence skin cancer development and cell differentiation.

TET enzymes are important for skin and hair development by controlling gene activity in specific areas.

Keratin K6irs is a marker for the inner root sheath of hair follicles in mice and humans.

Epidermal stem cells are diverse and vary in activity, playing key roles in skin maintenance and repair.
