Silver nanoparticles coated with substances like PEG showed strong antibacterial effects and improved wound healing when used in hydrogels.

Using human fat tissue derived stem cells in micrografts can safely and effectively increase hair density in people with hair loss.

Researchers developed a 3D model of human hair follicle cells that can help understand hair growth and test new hair loss treatments.

Different species and human skin models vary in their skin enzyme activities, with pig skin and some models closely matching human skin, useful for safety assessments and understanding the skin's protective roles.

New lipid nanoparticles show promise for delivering hair loss treatments but need improvement for better skin penetration.

Erbium glass laser treatment may help with skin remodeling, reduce inflammation, and improve skin cell maturation.

Scientists can grow human hair follicle stem cells in a lab without changing their nature, which could help treat hair loss.

Scientists have developed a method to keep chicken feather follicles alive and structurally intact in a lab for up to a week.

Umbilical cord-derived media is safe and effective for hair growth.

More research is needed before using brown fat to treat polycystic ovary syndrome.

Higher power CO2 laser causes more severe skin burns and damage.

Green tea component EGCG could potentially promote human hair growth.

Stump-tailed macaque best for researching hair loss causes and treatments.

Old treatments for other skin conditions showed promise for hair regrowth in mice with a hair loss condition.

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.

Medium lipophilic substances penetrate skin best, and adding ethanol can increase delivery to hair follicles.

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

Glycine reduces skin pigmentation by lowering melanin production.

Maidenhair fern extract reduced anxiety and depression in rats and may work due to its antioxidant and anti-inflammatory properties.

Runx genes are important for stem cell regulation and their roles in aging and disease need more research.

Certain cells in the adult mouse ear come from cranial neural crest cells, but muscle and hair cells do not.

Vimentin and transthyretin proteins are linked to black coat color in sheep.

Two new compounds can block androgen receptor activity in different ways and may lead to new treatments for androgen-related diseases.

Niosomes improve minoxidil skin delivery for hair loss treatment.

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

Fat-derived stem cells show promise for skin repair and reducing aging signs but need more research for consistent results.

Different lab conditions and light treatment methods change how human skin cells respond to light therapy.

Potassium channel openers like minoxidil help hair grow by acting on hair follicles.
