CD8+ T cells play a key role in graft-versus-host disease in certain mice models.

Hair follicle regeneration is possible but challenging, especially in humans, due to the need for specific cells and a better understanding of how they signal growth.

Pig skin cells can turn into mesodermal cells but lose their ability to become neural cells.

Adult esophageal cells can start to become like skin cells, with a key pathway influencing this change.

Activating β-catenin in mammary cells leads to changes that cause early-stage abnormal growths similar to skin structures.

New treatments for hair loss show promise, including plasma, stem cells, and hair-stimulating complexes, but more research is needed to fully understand them.

Hair growth can be induced by transplanting certain cells, but these cells lose their properties during culturing. The best cell interaction happens in a liquid medium under gravity, and using collagen doesn't help. Future research could focus on using growth factors to stimulate these cells.

Keratinocytes help heal skin wounds by interacting with immune cells and producing substances that kill pathogens.

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

The document concludes that specific cells are essential for hair growth and more research is needed to understand how to maintain their hair-inducing properties.

Fat cells in the skin help start healing and form important repair cells after injury.

Fetal skin heals without scarring due to unique cells and processes not present in adult skin healing.

Inactive hair follicle stem cells help prevent skin cancer.

Compartmentalized organization might be crucial for stem cells to effectively respond to growth or injury.

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

Hair can regrow after certain stem cells are lost because other stem cells can take over their role.

Scarring alopecia affects different hair follicle stem cells than nonscarring alopecia, and the infundibular region could be a new treatment target.

Fat cells are important for tissue repair and stem cell support in various body parts.

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

Wnt/ß-catenin signaling is crucial for regulating skin stem cells and hair growth, with the right levels and timing needed for proper function.

Further research is needed to improve hair regeneration using stem cells and nanomaterials.

A hydrogel made from pig fat helps wounds heal faster by regenerating skin fat cells.

High-dose radiation speeds up aging in skin stem cells.

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

A circular RNA helps cashmere goat hair cells become hair follicles by blocking a molecule to boost a gene important for hair growth.

Hair growth environment recreated with challenges; stem cells make successful skin organoids.

Keratin gene expression helps understand different types of skin cells and their development, and should be used carefully as biological markers.

Hair follicle stem cells can turn into many cell types and may help repair nerve damage and have other medical uses.

Disrupted cholesterol production impairs hair follicle stem cells, leading to hair loss.

The study found that stem cells and neutrophils are important for regenerating hair follicle structures in mice.
