Platelet-rich plasma may have some benefits in dermatology, but there's not enough evidence to widely recommend its use.

Smart biomaterials that guide tissue repair are key for future medical treatments.

Mice without the Sept4/ARTS gene heal wounds better due to more stem cells that don't die easily.

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

Muscles and nerves that cause goosebumps also help control hair growth.

Researchers created a fully functional, bioengineered skin system with hair from stem cells that successfully integrated when transplanted into mice.

Fat cells are important for healthy skin, hair growth, and healing, and changes in these cells can affect skin conditions and aging.

Mesenchymal stem cells show potential for skin healing and anti-aging, but more research is needed for safe use, especially regarding stem cells from induced pluripotent sources.

Dermal Papilla cells are a promising tool for evaluating hair growth treatments.

Fat tissue cells are a promising option for healing various diseases, but more research is needed to ensure they are safe and effective.

The document concludes that proper diagnosis and FDA-approved treatments for different types of hair loss exist, but treatments for severe cases often fail and future improvements may focus on hair follicle stem cells.

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 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.

Mice lacking a key DNA methylation enzyme in skin cells have a lower chance of activating stem cells necessary for hair growth, leading to progressive hair loss.

Wnt signaling is crucial for skin and hair development and its disruption can cause skin tumors.

Exosomes from dermal papilla cells help hair growth by making hair follicle stem cells multiply and change.

mTOR signaling helps activate hair stem cells by balancing out the suppression caused by BMP during hair growth.

Blue light promotes hair growth by interacting with specific receptors in hair follicles.

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

Maintaining DNA health in stem cells is key to preventing aging and tissue breakdown.

Treatment with plasma rich in growth factors improved hair density and thickness for hair loss patients.

PRP and HF-MSCs treatment improves hair growth, thickness, and density in androgenetic alopecia.

Cancer can hijack the body's cell repair system to promote tumor growth, and targeting this process may improve cancer treatments.

Tiny needles with valproic acid can effectively regrow hair.

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

The conclusion is that Fgf18 and Tgf-ß signaling could be targeted for hair loss treatments.

Abnormal Hedgehog signaling in blood cancers may help tumors grow and resist chemotherapy, suggesting potential for targeted treatments.

Beta-caryophyllene helps improve wound healing in mice, especially in females.

Different scaffold patterns improve wound healing and immune response in mouse skin, with aligned patterns being particularly effective.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.
