Radiation mainly affects keratinocyte stem cells, not melanocyte stem cells, causing hair to gray.

The meeting presented new findings on hair stem cells, pigmentation, genetics, and modern hair treatment techniques.

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

Hair graying is influenced by factors like nerves, fat cells, and immune cells, not just hair follicles.

Sox2 controls hair color by affecting pigment production in hair follicles.

Hair follicle dermal stem cells are key for regenerating parts of the hair follicle and determining hair type.

Skin stem cells can help improve skin repair and regeneration.

Stress can cause hair loss by affecting nerve-related hair growth, and noradrenaline might help prevent this.

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

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

Skin's epithelial stem cells are crucial for repair and maintenance, and understanding them could improve treatments for skin problems.

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

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

Light can turn on hair growth cells through a nerve path starting in the eyes.

New treatments targeting skin stem cells show promise for skin repair, anti-aging, and cancer therapy.

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

Sex hormones, especially estradiol, can change chicken feather shapes and colors.

Animals that change color with the seasons mainly do so in response to daylight changes, but climate change is causing camouflage problems that may require evolutionary changes.

Three specific proteins can turn adult skin cells into hair-growing cells, suggesting a new hair loss treatment.

Male hormones cause different growth in identical human hair follicles due to their unique epigenetic characteristics.

Experiments can shape how feathers grow and develop.

The 2015 Hair Research Congress concluded that stem cells, maraviroc, and simvastatin could potentially treat Alopecia Areata, topical minoxidil, finasteride, and steroids could treat Frontal Fibrosing Alopecia, and PTGDR2 antagonists could also treat alopecia. They also found that low-level light therapy could help with hair loss, a robotic device could assist in hair extraction, and nutrition could aid hair growth. They suggested that Alopecia Areata is an inflammatory disorder, not a single disease, indicating a need for personalized treatments.

Chicken feather growth involves specific genes and shares similarities with hair development.

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.

Hair follicle stem cells prevent melanocyte stem cells from differentiating by controlling retinoic acid levels.

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

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

A special environment is needed to fully activate sleeping stem cells.

BMP signaling is important for skin color, affecting melanin production, pigment spread, and cell movement.

BMP signaling controls hair growth and skin color.
