Scientists have found a way to create hair follicles from skin cells of newborn mice, which can grow and cycle naturally when injected into adult mouse skin.

Dermal papillae cells, important for hair growth, come from multiple cell lines and can be formed by skin cells, regardless of their origin or hair cycle phase. These cells rarely divide, but their ability to shape tissue may contribute to their efficiency in inducing hair growth.

Hair gets thinner, grayer, and changes texture with age due to genetics, environment, and cellular changes, affecting the growth cycle.

A new compound, BOI, can help hair grow by changing hair cycle phases and increasing certain cell contents.

Adult mouse skin contains stem cells that can create new hair, skin, and oil glands.

Lgr5 is a marker for active, long-lasting stem cells in mouse hair follicles.

Hair follicles are complex, dynamic mini-organs that help us understand cell growth, death, migration, and differentiation, as well as tissue regeneration and tumor biology.

VEGF helps hair grow and determines follicle size by increasing blood vessel growth.

Fat-related cells are important for initiating hair growth.

TGF-β2 helps activate hair follicle stem cells by counteracting BMP signals.

β-catenin in the dermal papilla is crucial for normal hair growth and repair.

Epithelial-mesenchymal interactions control hair growth cycles through specific molecular signals.

Middle-aged women with chronic telogen effluvium experience increased hair shedding but usually don't get significantly thinner hair.

The conclusion is that proper signaling is crucial for hair growth and development, and errors can lead to cancer or hair loss.

Noggin is necessary to start the hair growth phase in skin after birth.

Hair color production in mice is closely linked to the hair growth phase and may also influence hair growth itself.

Lactate production is important for activating hair growth stem cells.

The hedgehog signaling pathway is crucial for hair growth but not for the initial creation of hair follicles.

A new microneedle patch made from hair proteins helps regrow hair faster and better than current treatments.

Minoxidil boosts growth factor in hair cells, potentially promoting hair growth.

Wnt ligands are crucial for hair growth and repair.

Estrogen affects hair growth and skin cell multiplication.

The dermal papilla is crucial for hair growth and health, and understanding it could lead to new hair loss treatments.

Hair follicle stem cells can generate all hair cell types, skin, and sebaceous glands.

Understanding hair follicle anatomy helps diagnose hair disorders.

The HR protein helps hair grow by blocking a hair growth inhibitor, aiding in hair follicle regeneration.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Low fluence photoepilation temporarily removes hair by targeting the hair follicle's pigmented area without severe damage.

We need more research on human hair follicle pigmentation, not just mouse models.

Hair follicles produce and respond to melatonin, affecting hair growth and sensitivity to estrogen.
