Environmental factors at different levels control hair stem cell activity, which could lead to new hair growth and alopecia treatments.

The conclusion is that Fgf18 and Tgf-ß signaling could be targeted for hair loss treatments.

BLIMP1 is essential for skin maintenance but not for defining sebaceous gland progenitors.

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.

Fat cells are important for healthy skin, hair growth, and healing, and changes in these cells can affect skin conditions and aging.

The study showed that some hair follicle stem cells wake up to grow hair while others stay asleep, and that the environment around them is important for hair growth.

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.

mTOR signaling helps activate hair stem cells by balancing out the suppression caused by BMP during hair growth.

Researchers identified potential markers for human hair color stem cells.

Hair follicle stem cells can turn into many cell types and may help repair nerve damage and have other medical uses.

Vav2 changes how hair follicle stem cells' genes work as they age, which might improve regeneration but also raise cancer risk.

Changing the environment around stem cells could help tissue repair, but it's hard to be precise and avoid side effects.

The research found that different types of fibroblasts are involved in wound healing and that some blood cells can turn into fat cells during this process.

Hair can regrow after certain stem cells are lost because other stem cells can take over their role.

Hair follicle stem cells in hairpoor mice are disrupted, causing hair loss.

Stem cell offspring help control their parent stem cells, affecting tissue health, healing, and cancer.

Epigenetic changes control how adult stem cells work and can lead to diseases like cancer if they go wrong.

Wnt1a-conditioned medium from stem cells helps activate cells important for hair growth and can promote hair regrowth.

Removing a specific gene in certain skin cells causes hair loss on the body by disrupting normal hair development.

Fat cells help recruit healing cells and build skin structure during wound healing.

Cells in hair follicles help create fat cells in the skin by releasing a protein called Sonic Hedgehog.

Glutamine metabolism affects hair stem cell maintenance and their ability to change back to stem cells.

LGR5 is a common marker of hair follicle stem cells in different animals and is important for hair growth and regeneration.

BMP4 helps stem cells turn into pigment-producing cells, affecting hair color and growth.

Hox proteins help maintain keratinocyte identity by regulating miRNA expression.

Alkaline Ceramidase 1 prevents early hair loss in mice by keeping hair follicle stem cells balanced.

Dermal papilla cells are key for hair growth and color, influencing hair type and size, and their interaction with stem cells could help treat hair loss and color disorders.

The skin is the largest organ, protecting the body, regulating temperature, and producing hormones.

Canine hair follicles have stem cells similar to human hair follicles, useful for studying hair disorders.

The Msi2 protein helps keep hair follicle stem cells inactive, controlling hair growth and regeneration.
