Skin and hair can help us understand organ regeneration, especially how certain stem cells might be used to form new organs.

Both immature and mature fat cells are important for hair growth cycles, with immature cells promoting growth and mature cells possibly inhibiting it.

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

Epidermal stem cells have various roles in skin beyond just maintenance, including forming specialized structures and aiding in skin repair and regeneration.

Eating less can slow aging and help keep stem cells healthy by cleaning out damaged cell parts.

In vivo lineage labelling is better than in vitro methods for identifying and understanding stem cells.

Lanyu pigs show that partial-thickness wounds can partially regenerate important skin structures, which may help improve human skin healing.

Special immune cells called Treg cells are important for maintaining and regenerating hair by activating a specific growth signal in hair stem cells.

Using micro skin tissue columns improves skin wound healing and reduces scarring.

Exosomes help nerve fibers grow by affecting specific cell signaling pathways.

New hair can grow from large wounds in mice, but less so as they age, involving reprogramming of skin cells and specific molecular pathways.

Researchers found 44 proteins that change during different hair growth stages and may be important for hair follicle function.

The document concludes that stem cell inactivity is actively controlled and important for tissue repair and balance.

Celsr1 is crucial for skin cell alignment, while Celsr2 has little effect on this process.

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

SOX9 helps determine stem cell roles by interacting with DNA and proteins that control gene activity.

Charnoly bodies could be a marker for cell damage, and certain nutrients and proteins might prevent them, potentially helping with brain diseases and cancer.

Extracts from three Polynesian plants were found to promote hair growth by affecting cell growth and gene expression related to hair.

The research reveals how early embryonic mouse skin develops from simple to complex structures, identifying various cell types and their roles in this process.

The document concludes that identifying the specific cells where skin cancers begin is important for creating better prevention, detection, and treatment methods.

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

Different types of inactive melanocyte stem cells exist with unique characteristics and potential to develop into other cells.

Maintaining DNA integrity in stem cells is crucial to prevent aging and cancer.

Skin fat has important roles in hair growth, skin repair, immune defense, and aging, and could be targeted for skin and hair treatments.

The document concludes that understanding dermal papilla cells is key to improving hair regeneration treatments.

P-cadherin is important for hair growth and health, and its problems can cause hair and skin disorders.

The document concludes that pig iPSCs show promise for transplant therapies and the field is advancing in controlling cell behavior for biology and medicine.

The nucleus is key in controlling skin growth and repair by coordinating signals, gene regulators, and epigenetic changes.

Treg cell-based therapies might help treat hair loss from alopecia areata, but more research is needed to confirm safety and effectiveness.

Hair growth is driven by cells that move and change like a conveyor belt.
