Rare ULBP3 gene changes may raise the risk of Alopecia areata, a certain FAS gene deletion could cause a dysfunctional protein in an immune disorder, and having one copy of a specific genetic deletion is okay, but two copies cause sickle cell disease.

Chromosomal changes, including those in the WRN gene and rDNA, may significantly contribute to aging.

Younger mice's hair-follicle stem cells are better at turning into heart cells than older mice's.

Wnt signaling is crucial for pigmented hair regeneration by controlling stem cell activation and differentiation.

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

Aging changes hair stem cells and their environment, leading to gray hair and hair thinning, but understanding these changes could help develop treatments for hair regeneration.

The environment around melanocyte stem cells is key for hair regeneration and color, with certain injuries affecting hair color and potential treatments for pigmentation disorders.

A certain signaling pathway in mice, when increased, causes hair to gray by depleting the cells that give hair its color.

EdnrB signaling helps melanocyte stem cells regenerate and could be targeted to treat pigmentation issues.

Hair follicles could be used to noninvasively monitor our body's internal clock and help identify risks for related diseases.

Melanocyte development from neural crest cells is complex and influenced by many factors, and better understanding could help treat skin disorders.

Nerves and chemicals in the body can affect hair growth and loss.

Stress, nutritional issues, and chronic diseases can cause hair loss, and nail changes may signal internal diseases; treatment focuses on the underlying cause.

Researchers found that hair shedding happens mostly when new hair is growing and involves a unique process.

Hormones and neuroendocrine factors control hair growth and color, and more research could lead to new hair treatment options.

Understanding hair biology is key to developing better treatments for hair and scalp issues.

Gamma-ray exposure can cause long-lasting damage to hair follicles, affecting hair structure and color.

Gamma rays did not change hair follicle density but increased white and hypopigmented hairs in mice.

P-cadherin is important for hair growth and health, and its problems can cause hair and skin disorders.

SKPs are similar to adult skin stem cells and could help in skin repair and hair growth.

Regenerated fully functional hair follicles using stem cells, with potential for hair regrowth therapy.

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

Scientists have made progress in creating replacement teeth, hair, and glands that work, which could lead to new treatments for missing teeth, baldness, and dryness conditions.

Topical treatments can deliver active molecules to skin stem cells, potentially helping treat skin and hair disorders, including skin cancers and hair loss.

Stress can worsen skin and hair conditions by affecting the skin's immune response and hormone levels.

Melanocytes are important for skin and hair color and protect the skin from UV damage.

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.

Gene regulation could revolutionize hair color by altering pigmentation from within.

The human scalp hair bulb contains different types of melanocytes with varying abilities to produce melanin.

Hair follicles are essential for skin health, aiding in hair growth, wound healing, and immune function.
