Using a patient's own fat tissue helped treat hair loss caused by an injury.

Arrector pili muscle regulates hair follicle stem cells, DNA methylation needed for hair cycling, and Wnt/B-catenin signaling starts hair growth.

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

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.

Stress hormone corticosterone blocks a growth factor to slow down hair stem cell activity and hair growth.

DNMT3A is crucial for healthy skin and hair growth.

The Wnt/β-catenin pathway helps tissue regeneration but can also cause fibrosis, and drugs that inhibit this pathway may aid in healing skin and heart tissues.

Old people have less hair because their hair follicles don't regenerate as well, not because of fewer stem cells, and a protein called follistatin might help reactivate hair growth.

The document concludes that the skin's immune system is complex, involving interactions with hair follicles, nerves, and microbes, and can protect or cause disease, offering targets for new treatments.

Cell aging can be both good and bad for tissue repair.

Deer antler stem cell fluid helps regenerate tissue better than fat-derived stem cell fluid.

Sonic hedgehog signaling is crucial for hair growth and maintaining hair follicle identity.

The document concludes that understanding how the skin's immune system and inflammation work is complex and requires more research to improve treatments for skin diseases.

The study found that expanded skin regenerates similarly to normal skin, with 77 genes playing a role in the process.

Flightless I protein affects hair growth, with low levels delaying it and high levels increasing hair length in rodents.

EdnrB signaling helps melanocyte stem cells regenerate and could be targeted to treat pigmentation issues.

Exosomes could potentially enhance tissue repair and regeneration with lower rejection risk and easier production than live cell therapies.

Hair can regrow in large wounds through a process similar to how hair forms in embryos, and understanding this could lead to new treatments for hair loss or scarring.

The conclusion is that teeth, hair, and claws have similar stem cell niches, which are important for growth and repair, and more research is needed on their regulation and potential markers.

Certain sex hormones and antiandrogens can either slow down or speed up the growth of human hair follicle cells depending on their concentration.

Vitamin C helps adipose-derived stem cells grow and may support hair growth.

The study found stem cells in minor salivary glands that can differentiate and are involved in tumor formation when exposed to tobacco.

Scientists made working hair follicles using stem cells, helping future hair loss treatments.

γδ T cells help with hair growth during wound healing in mice.

Damage to skin releases dsRNA, which activates TLR3 and helps in skin and hair follicle regeneration.

Hair growth phase and certain genes can speed up wound healing, while an inflammatory mediator can slow down new hair growth after a wound. Understanding these factors can improve tissue regeneration during wound healing.

The conclusion is that hair growth can be improved by activating hair cycles, changing the surrounding environment, healing wounds to create new hair follicles, and using stem cell technology.

Vitamin D3 can help improve hair growth by enhancing the function of specific skin cells and could be useful in hair regeneration treatments.

Hair follicles can regrow in wounded adult mouse skin using a process like embryo development.

Breadfruit is nutritious and has potential health and medicinal benefits, but is currently underused.
