Ionizing radiation causes irreversible skin damage, with single doses leading to acute injury and hair graying, and fractional doses causing more severe long-term tissue damage.

Quercetin significantly helps hair growth by activating hair follicles and improving blood vessel formation around them.

Epidermal stem cells have potential for personalized regenerative medicine but need careful handling to avoid cancer.

TR3 is mainly found in hair follicle stem cells and may be involved in hair loss.

2011 dermatology discussions highlighted stem cell hair treatments, new lichen planopilaris therapies, skin side effects from cancer drugs, emerging allergens, and the link between food allergies and skin issues.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

Blue-light activation of TrkA improves hair-follicle stem cells' ability to become neurons and glial cells.

Hair follicle stem cells might help treat traumatic brain injury.

Human sweat glands have a type of stem cell that can grow well and turn into different cell types.

Canine epidermal neural crest stem cells could be a promising treatment for spinal cord injuries in dogs.

Hair follicles and deer antlers regenerate similarly through stem cells and are influenced by hormones and growth factors.

Implanting hair-follicle stem cells in mice brains helped repair brain bleeding and reduced brain inflammation.

The document concludes that while some organisms can regenerate body parts, mammals generally cannot, and cancer progression is complex, involving mutations rather than a strict stem cell hierarchy.

Keratinocytes and adipose-derived stem cells can effectively heal difficult skin wounds.

TGF-β is crucial for tissue repair and can cause diseases if not properly regulated.

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