Keratin is crucial for keeping skin cells healthy and its changes can lead to diseases and affect cell behavior.

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

Dermal papilla cells help wounds heal better and can potentially grow new hair.

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

Hair follicle stem cells help skin heal and grow during stretching.

The document concludes that understanding how adult stem and progenitor cells move is crucial for tissue repair and developing cell therapies.

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

SHISA6 helps maintain certain stem cells in mouse testes by blocking signals that would otherwise cause them to differentiate.

Bird foot scales develop differently and can repair but not fully regenerate due to the lack of specialized stem cell areas.

Some stem cells in the body rarely divide, which could help create better treatments for diseases and aging.

MED1 affects skin wound healing differently in young and old mice.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

Epidermal Wnt/β-catenin signaling controls fat cell formation and hair growth.

Human foreskin does not show aging or reduced cell growth after radiation, and H2A.J is not a good marker for radiation-induced aging.

Wound healing insights can improve regenerative medicine.

Blocking Wnt/β-catenin signaling with EGF receptor is necessary for proper hair growth.

The document concludes that stem cells and their environments are crucial for skin and hair health and have potential for medical treatments.

Nerves are crucial for the regeneration of various body parts in many animals.

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.

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.

The sebaceous gland has more roles than just producing sebum and contributing to acne, and new research could lead to better skin disease treatments.

Hair follicles are complex, dynamic mini-organs that help us understand cell growth, death, migration, and differentiation, as well as tissue regeneration and tumor biology.

Hair follicle regeneration possible, more research needed.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

The niche environment controls stem cell behavior and plasticity, which is important for tissue health and repair.

Topical drugs and near-infrared light therapy show potential for treating alopecia.

Human skin can provide stem cells for tissue repair and regeneration, but there are challenges in obtaining and growing these cells safely.

Artemis dysfunction might cause hair loss through telomere shortening.

Hair follicle stem cells are promising for wound healing but require more research for safe clinical use.
