Skin-derived stem cells grow faster and are easier to obtain than hair follicle stem cells, but both can become various cell types.

Nivolumab treatment led to hair regrowth in a man with metastatic melanoma and alopecia areata.

Minoxidil improved hair growth in a child with a rare genetic disorder.

4-Aminopyridine improves skin wound healing and tissue regeneration by increasing cell growth and promoting nerve repair.

ERG increases SOX9, promoting prostate cancer growth and invasion.

Stem cells are crucial for wound healing and understanding their role could lead to new treatments, but more research is needed to answer unresolved questions.

Different small areas within hair follicles send specific signals that control what type of cells stem cells become.

The study identified unique genes in hair follicle cells and their environment, suggesting these genes help organize cells for hair growth.

Dermal fibroblasts have adjustable roles in wound healing, with specific cells promoting regeneration or scar formation.

Activating a protein called β-catenin in adult skin can make it behave like young skin, potentially helping with skin aging and hair loss.

The Hedgehog signaling pathway is important for skin and hair growth and can lead to cancer if it doesn't work right.

Human stem cells can help form hair follicles in mice.

CD34+ and CD34- melanocyte stem cells have different regenerative abilities.

Certain RNA molecules are important for the development of wool follicles in sheep.

Melanoma's complexity requires personalized treatments due to key genetic mutations and tumor-initiating cells.

Hair becomes gray and thin as we age, and while most hair loss in older people is due to genetics, there's a chance for gray hair to regain color under certain conditions.

Reducing Tyrosinase prevents mature color pigment cells from forming in mouse hair.

The right amount of retinoic acid is essential for normal hair growth and development.

Fat under the skin releases HGF which helps hair grow and gain color.

Hair graying may be caused by stem cell depletion from stress or melanocyte damage.

Hair follicle stem cells can become different cell types and may help treat neurodegenerative disorders.

Genetic changes in mice help understand skin and hair disorders, aiding treatment development for acne and hair loss.

Rats can't grow new hair follicles after skin wounds, unlike mice, due to differences in gene expression and response to WNT signaling.

Human hair follicles can be used to create stem cells that might help clone hair for treating hair loss or helping burn patients.

The enzyme DHHC13 is essential for healthy hair and skin, and its deficiency leads to hair loss and skin problems.

Hair is important for protection, social interaction, and temperature control, and is made of a growth cycle-influenced follicle and a complex shaft.

The genes KRT25 and SP6 affect curly hair in horses, with KRT25 also causing hair loss. If both genes are mutated, the horse gets curly hair and hair loss. KRT25 can hide the effect of SP6.

A specific group of skin stem cells was found to help maintain hair follicle cells.
