Old people have less hair because their hair follicles don't regenerate as well, not because of fewer stem cells, and a protein called follistatin might help reactivate hair growth.

Hair follicle stem cells change states with age, affecting hair growth and aging.

Dental pulp stem cells might not reliably become neurons.

Stem cell therapy shows promise for treating hair loss in androgenetic alopecia.

Cell death shapes skin stem cell environments, affecting inflammation, repair, and cancer.

HPV8 causes hair follicle stem cells to grow, leading to skin lesions.

TGF-β2 helps activate hair follicle stem cells by counteracting BMP signals.

Special particles from umbilical cord stem cells help heal skin wounds in diabetic mice by preventing certain immune cell death.

Autophagy helps activate hair stem cells and hair growth by changing their energy use to glycolysis.

New treatments using stem cells and other methods show promise for promoting hair growth in androgenetic alopecia.

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

Different signals work together to change gene activity and guide hair follicle stem cells to become specific cell types.

Hair follicles are valuable for regenerative medicine and wound healing.

Transplanted hair follicle stem cells improved brain function and reduced damage after a stroke in rats.

A protein called desmoglein 3 is important for keeping hair follicle stem cells inactive and helps in their regeneration.

Low-dose acitretin helps nail psoriasis, stem cells may treat scarring alopecia, Chinese men have lower baldness rates, lateral foldplasty is good for ingrown toenails, hair diameter helps diagnose female baldness, childhood trauma linked to alopecia areata, certain hair-weaving leads to scalp conditions in African American women, and new methods for hair research and understanding hair and sweat gland development were introduced.

Activating Nrf2 in skin cells speeds up wound healing by increasing the growth of certain stem cells.

The document concludes that stem cell therapies lack solid proof of effectiveness, except for blood system treatments, and criticizes the ethical issues and commercial exploitation in the field.

Transit-amplifying cells are crucial for tissue repair and can contribute to cancer when they malfunction.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

Blocking both main energy pathways can stop hair follicle stem cell-induced skin cancer growth.

Nestin-expressing cells turn into a specific type of skin cell in hair follicles during development and in adults.

Stem cell-derived conditioned medium shows promise for treating various medical conditions but requires standardized production and further validation.

New treatments for hair loss could involve using stem cells and a process called the Wnt/beta-catenin pathway to stimulate hair growth.

Skin cells show flexibility in healing wounds and forming tumors, with potential for treating hair disorders and chronic ulcers.

Scientists developed a new way to study mutations in a skin condition using blood cells, which may help diagnose and treat the disease.

Aging mice have slower hair regeneration due to changes in signal balance, but the environment, not stem cell loss, controls this, suggesting treatments could focus on environmental factors.

Stem cell therapy is a promising approach for hair regrowth despite potential side effects.

New hair can grow from large wounds in mice, but less so as they age, involving reprogramming of skin cells and specific molecular pathways.
