Skin stem cells interacting with their environment is crucial for maintaining and regenerating skin and hair, and understanding this can help develop new treatments for skin and hair disorders.

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

Hair growth and development are controlled by specific signaling pathways.

Gab1 protein is crucial for hair growth and stem cell renewal, and Mapk signaling helps maintain these processes.

Cells with active Wnt signaling are less likely to turn into cancer when exposed to a cancer-causing gene.

Different types of skin fibroblasts have unique roles in skin health and disease.

Sheep hair follicle cells can grow a lot but need the dermal papilla to do so.

PTEN helps control the number and health of skin stem cells by working with the protein BMAL1.

Follistatin and LIN28B together improve the ability of inner ear cells in mice to regenerate into hearing cells.

Mice without certain skin enzymes have faster hair growth and bigger eye glands.

EGFR helps control how hair grows and forms without needing p53 protein.

UV exposure reduces Lgr6+ stem cells in mouse skin and they don't significantly contribute to skin cancer development.

Thymic stromal lymphopoietin (TSLP) promotes hair growth, especially after skin injury.

Overactive Wnt signaling in mouse skin stem cells causes acne-like cysts and shrinking oil glands, which some treatments can partially fix.

The research showed how melanocytes develop, move, and respond to UV light, and their stem cells' role in hair color and skin cancer risk.

Vitamin D receptor is crucial for skin wound healing.

Epidermal stem cells help heal severe skin wounds and have potential for medical treatments.

Wnt signaling is crucial for skin development and hair growth.

A new 3D culture system helps grow and study mouse skin stem cells for a long time.

Lack of Ctip2 in skin cells delays wound healing and disrupts hair follicle stem cell markers in mice.

Stem cells, especially from fat tissue and Wharton's jelly, can potentially regenerate hair follicles and treat hair loss, but more research is needed to perfect the treatment.

Keratin 15 expression in skin cells is regulated by two mechanisms involving PKC/AP-1 and FOXM1.

Stem cells can help other stem cells by producing supportive factors.

The conclusion is that understanding how hair follicle stem cells live or die is important for maintaining healthy tissue and repairing injuries, and could help treat hair loss, but there are still challenges to overcome.

Sox21 is crucial for tooth development and enamel formation by preventing cells from changing into a different type.

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

Different species use the same genes for tooth regeneration.

Lack of Crif1 in hair follicle stem cells slows down hair growth in mice.

Overexpression of sPLA2-IIA in mouse skin reduces hair stem cells and increases cell differentiation through JNK/c-Jun pathway activation.

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