Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

The model successfully grew and differentiated hair follicle cells in the lab.

Keratin 79 cells help form and regenerate hair canals.

Hair follicles form hard α-keratin filaments in four steps, showing structural differences.

Abnormal keratin expression in mice causes severe oral issues, affecting feeding.

Hair proteins change location and structure as hair cells mature.

Keratin-associated proteins are part of the developing hair fiber cuticle.

Nestin-expressing cells turn into a specific type of skin cell in hair follicles during development and in adults.

One type of progenitor cell can maintain normal skin in mice.

Retinoids can help treat skin disorders by improving the skin's outer layer.

Keratinocyte stem cells help regenerate and repair cornea, skin, and hair.

Loss of keratin K2 causes skin problems and inflammation.

The K15 promoter effectively targets stem cells in the hair follicle bulge.

Mutant keratins cause inflammation in Epidermolysis Bullosa Simplex, suggesting targeting them could help treat the disorder.

Skin stem cells help repair damage and maintain healthy skin.

Keratin in mouse hair follicles is complex and plays specific roles.

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

K15 gene is mainly active in the basal layers of hair follicles and epithelia, aiding early skin cell development.

Myeloid cells can turn into skin and hair cells to help heal wounds.

Recombinant keratins can form useful structures for medical applications, overcoming natural keratin limitations.

Dermal papilla cells can help form hair-like structures in lab-grown skin cells.

Hair follicle stem cells are crucial for touch sensation and proper nerve structure in mice.

Keratose, derived from human hair, is a non-toxic biomaterial good for tissue regeneration and integrates well with body tissues.

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

Scientists found a new type of skin cell that could help with skin repair and these cells work better with a certain protein.

Sweat glands and hair follicles are determined by opposing signals, with BMPs promoting sweat glands and blocking BMPs leading to hair follicles.
