Melatonin affects skin and hair color and protects skin cells, with potential benefits for hair growth and skin health.

The protein EZH2 blocks microRNA-22, increasing STK40 protein, which helps hair follicle stem cells change and grow hair.

BMI1 is essential for preventing hair greying and maintaining hair color.

Notch/CSL signaling controls hair follicle differentiation through Wnt5a and FoxN1.

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

The 2004 hair research meeting presented new findings on hair cell differentiation, genetic factors in hair loss, hair pigmentation, and potential targeted therapies.

Hair stem cells produce a protein called COL17A1 that plays a key role in their development and is linked to hair thinning and baldness.

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

Aging in hair follicle stem cells leads to hair graying, thinning, and loss.

An 81-year-old man's white hair began to regain its original color while he was treated with lenalidomide, suggesting that graying hair might be reversible.

The research found that a specific skin cell type not only triggers hair growth but also controls hair color, and that aging can lead to hair loss and color changes.

The symposium showed that stem cells are key for understanding and treating skin diseases and for developing new skin models and therapies.

The conclusion is that proper signaling is crucial for hair growth and development, and errors can lead to cancer or hair loss.

Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.

The document concludes that while significant progress has been made in understanding skin biology and stem cells, more research is needed to fully understand their interactions with their environment.

Hair greying is caused by oxidative stress damaging hair follicles and melanocytes.

Certain immune system proteins are important for skin healing but can cause problems if there are too many of them.

Mice skin has components that could help with hair growth and might be used for diabetes treatment.

Skin organoids are a promising new model for studying human skin development and testing treatments.

Proper control of β-catenin activity is crucial for development and preventing diseases like cancer.

The document concludes that understanding hair follicles requires more research using computational methods and an integrative approach, considering the current limitations in hair treatment products.

The conclusion is that skin and hair patterns are formed by a mix of cell activities, molecular signals, and environmental factors.

Topical L-thyroxine may help with wound healing and hair growth but should be used short-term due to potential risks.

Stress turns hair white by depleting color-giving cells in hair follicles through a specific neurotransmitter related to the body's stress response.

Gray hair is caused by reduced melanin production or transfer issues, linked to aging and possibly health conditions, with treatments focusing on color camouflage.

Topical tretinoin may increase beard hair density.

Dermal papilla cells are key for hair growth and color, influencing hair type and size, and their interaction with stem cells could help treat hair loss and color disorders.

Certain cells around hair follicles help improve skin regeneration for potential use in skin grafts.

Epidermal stem cells show promise for future dermatology treatments due to ongoing advancements.

MOF controls key genes for skin development by regulating mitochondrial and ciliary functions.
