Estrogen can temporarily slow down hair growth but this can be reversed.

Stem cell niches support, regulate, and coordinate stem cell functions.

GRK2 is essential for healthy hair follicle function, and its absence can lead to hair loss and cysts.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

miR-22, a type of microRNA, controls hair growth and its overproduction can cause hair loss, while its absence can speed up hair growth.

The study showed that hair follicle stem cells can maintain and organize themselves in a lab setting, keeping their ability to renew and form hair and skin.

Scientists made working hair follicles using stem cells, helping future hair loss treatments.

The document concludes that adult mammalian skin contains multiple stem cell populations with specific markers, important for understanding skin regeneration and related conditions.

The research identified genes that explain why some sheep have curly wool and others have straight wool.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

Alpinetin helps grow hair by turning on hair stem cells and is safe for use.

Aging reduces skin stem cell function, leading to changes like hair loss and slower wound healing.

Mouse cell exosomes help hair regrowth and wound healing by activating a specific signaling pathway.

The research identified key molecules that help hair matrix and dermal papilla cells communicate and influence hair growth in cashmere goats.

Overactivating Hedgehog signaling makes hair follicle cells in mice grow hair faster and create more follicles.

Hoxc genes control hair growth through Wnt signaling.

Circadian clock genes are important for hair growth and may affect aging-related hair loss and graying.

Blocking YAP/TAZ could be a new way to treat skin cancer.

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.

Lung repair involves both dedicated and flexible stem cells, important for developing new treatments.

Lgr5 is a marker for active, self-renewing stem cells in the intestine and skin, important for tissue maintenance.

Different types of skin cells have unique genetic markers that affect how likely they are to spread cancer.

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.

Scientists created stem cells that can grow hair and skin.

Human hair follicle stem cells show signs of low oxygen levels, which may be important for hair growth and preventing baldness.

Adult stem cells with Tp63 can form hair and skin cells when placed in new skin, showing they have hidden abilities for skin repair.

The document concludes that while significant progress has been made in understanding skin biology and stem cells, more research is needed to fully understand their interactions with their environment.

Increasing Rps14 helps grow more inner ear cells and repair hearing cells in baby mice.

Men with baldness due to androgenetic alopecia still have hair stem cells, but lack specific cells needed for hair growth.
