Embryonic and adult stem cells are valuable for improving skin grafts and cell therapy.

Hair follicle stem cells have significant potential for treating various disorders.

PRP and HF-MSCs treatment improves hair growth, thickness, and density in androgenetic alopecia.

Understanding how melanocyte stem cells work could lead to new treatments for hair graying and skin pigmentation disorders.

Hair loss and aging are caused by the breakdown of a key protein in hair stem cells.

TPA promotes hair growth by increasing stem cell activity and activating specific cell signals.

Researchers successfully isolated and identified key stem cells in human hair follicles, which could help develop new skin and hair treatments.

Disrupting Smad4 in mouse skin causes early hair follicle stem cell activity that leads to their eventual depletion.

Stem cells regenerate tissues and their behavior varies by environment, suggesting the hematopoietic system model may need revision.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

Shi-Bi-Man activates hair follicle stem cells and promotes hair growth by changing lactic acid metabolism and other cellular processes.

Stem cells and their surrounding environment in hair follicles work closely together, affecting hair growth and having implications for cancer and tissue regeneration.

Mice with too much sPLA₂-IIA have hair loss and poor wound healing due to abnormal hair growth and stem cell depletion.

Arrector pili muscle regulates hair follicle stem cells, DNA methylation needed for hair cycling, and Wnt/B-catenin signaling starts hair growth.

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

Skin stem cells can help improve skin repair and regeneration.

The protein SLC1A3 is important for activating skin stem cells and is necessary for normal hair and skin growth in mice.

Wnt1a helps keep cells that can grow hair effective for potential hair loss treatments.

Exosomes from dermal papilla cells help hair follicle stem cells grow and survive.

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