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

Hair can regrow in large wounds through a process similar to how hair forms in embryos, and understanding this could lead to new treatments for hair loss or scarring.

N-acetyl-L-cysteine (NAC) can prevent DNA damage and protect cells from harm.

Transplanted transected hair follicles can survive but grow at unsatisfactory rates and are thinner, suggesting limited potential for unlimited donor hair supply.

The conclusion is that certain cell interactions and signals are crucial for hair growth and regeneration.

Epidermal stem cells could lead to new treatments for skin and hair disorders.

Cutting hair follicles into pieces for transplantation results in poor growth and thinner hair, and the technique is more invasive than previously thought.

Human hair follicles produce and respond to erythropoietin, helping protect against stress.

Proteoglycans are important for hair growth, and a specific treatment can help reduce hair loss.

Human hair grows better in a special gel that mimics skin.

Removing senescent cells can improve hair growth and regeneration.

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

Keratoacanthoma comes from hair follicle cells.

Melanocytes are diverse cells important for pigmentation and skin health, influenced by genetics and environment.

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

Extracellular vesicles, including exosomes from certain cells, can stimulate hair growth.

Different ectodermal organs like hair and feathers regenerate differently, with specific stem cells and signals involved in their growth and response to the environment.

The research suggests immune system changes and specific gene expression may contribute to male hair loss, proposing potential new treatments.

Alopecia areata is an autoimmune disease where T cells attack hair follicles.

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

Hair transplant surgery can rebuild muscle and nerve connections, allowing transplanted hairs to stand up like normal hairs.

Intestinal stem cells can help repair skin damage from radiation.

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

Fat-derived stem cells show promise for skin repair and reducing aging signs but need more research for consistent results.

Mice can grow new hair follicles after skin wounds through a process not involving existing hair stem cells, but requiring more research to understand fully.

Brain hormones significantly affect hair color and could potentially be used to prevent or reverse grey hair.

Bone marrow stem cells and their medium help hair regrowth.

Keratin 15 is not a reliable sole marker for identifying epidermal stem cells because it's found in various cell types.

Hair growth is influenced by various body and external factors, and neighboring hairs communicate to synchronize regeneration.

New treatments for hair loss, fertility, and wound healing are being explored.
