Hard α-keratin has a universal molecular structure with a specific superlattice arrangement.

Overexpressing CtBP1 in skin cells causes skin and hair problems.

Mouse and human keratin 16 can both form filaments, with differences likely due to the tail domain, not the helical domain.

Follistatin and LIN28B together improve the ability of inner ear cells in mice to regenerate into hearing cells.

Mice without the vitamin D receptor have bone issues and other health problems, suggesting vitamin D is important for preventing various diseases in humans.

The vitamin D receptor is crucial for bone health and affects various body systems, with mutations potentially leading to disease.

MicroRNAs are crucial in controlling cell signaling, affecting cancer and tissue regeneration.

Skin stem cells are crucial for maintaining and repairing the skin and hair, using a complex mix of signals to do so.

The document concludes that skin stem cells are important for hair growth and wound healing, and could be used in regenerative medicine.

The vitamin D receptor is involved in multiple body functions beyond calcium regulation, including immune response and rapid reactions not related to gene activity.

Changing the environment around stem cells could help tissue repair, but it's hard to be precise and avoid side effects.

Hair follicle development is controlled by interactions between skin tissues and specific molecular signals.

Anabolic steroids can build muscle and strength but have risks and need more research on their clinical benefits and side effects.

Understanding phenotypic plasticity is crucial for developing effective cancer therapies.

Prostate cancer cells can make their own androgens to activate the androgen receptor, and treatments like abiraterone may increase this ability, suggesting new therapies should target the entire steroid-making pathway.

β-catenin is essential for stem cell activation and proliferation in hair follicles.

The circadian clock affects skin stem cell behavior, impacting aging and cancer risk.

Certain proteins, Lgr5 and Lgr6, are important markers of adult stem cells and are involved in tissue repair and cancer development.

Wnt signaling is crucial for skin development and health, and its disruption can cause skin diseases.

Stem cell offspring help control their parent stem cells, affecting tissue health, healing, and cancer.

Apoptosis is essential for human skin development and forming a functional epidermis.

Understanding different species' regeneration can improve mammalian healing.

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

The timing of when the gene Bmal1 is active affects aging and survival, with its absence during development, not adulthood, leading to premature aging.

Skin stem cells help repair damage and maintain healthy skin.

Planarian regeneration begins with a specific gene activation caused by injury, essential for healing and tissue regrowth.

Stem cells help heal skin wounds by moving and changing roles, working with other cells, and needing more research on their activation and behavior.

Different types of skin cells play specific roles in development, healing, and cancer.

Hair follicle growth and development are controlled by specific genes and molecular signals.
