The model can effectively test gene functions and drug responses in human skin.

The enzyme CD73 helps control human hair growth and could be targeted to treat hair growth disorders.

The vitamin D receptor is crucial for bone health and affects various body systems, with mutations potentially leading to disease.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Probiotic bacteria improved skin and hair health in aged mice.

Stress increases a factor in mice that leads to hair loss, and blocking this factor may prevent it.

Advanced human skin models improve drug development and could replace animal testing.

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

Older skin has higher cancer risk due to inflammation and stem cell issues.

Men are more likely to get infectious skin diseases, while women are more prone to autoimmune and pigment-related skin conditions, influenced by biological and environmental factors.

MicroRNAs play a crucial role in skin and hair health, affecting everything from growth to aging, and could potentially be used in treating skin diseases.

Skin and hair can regenerate after injury due to changes in gene activity, with potential links to how cancer spreads. Future research should focus on how new hair follicles form and the processes that trigger their creation.

Zinc supplementation may help improve treatment outcomes for chronic hepatitis C.

Melanocytes are important for skin and hair color and protect the skin from UV damage.

Radiation therapy damages skin structure and immune function, causing inflammation and potential hair loss.

Microglia, the brain's immune cells, may contribute to Polycystic Ovary Syndrome (PCOS) by altering the female brain's structure and function, with kisspeptin neurons and GABA neurotransmitters also playing a role.

Fish oil improves skin health in people with diabetes and high cholesterol.

AP-2α and AP-2β proteins are essential for healthy adult skin and hair.

Unconventional lymphocytes are important for quick immune responses and healing of skin and mucosal barriers.

Damaged hair follicles make mice more prone to skin inflammation and skin cancer after UV exposure.

Activating TLR9 helps heal wounds and regrow hair by using specific immune cells.

Trichloroethylene causes skin inflammation in mice by increasing certain immune proteins.

Innate immunity genes in hair follicle stem cells might have new roles beyond traditional immune functions.

DHT may reduce inflammation caused by certain bacteria in skin cells.

Different genes and pathways are active in yak skin and hair cells, affecting hair growth and immune responses.

Skin lymphatic vessels are essential for hair growth.

Leptin, a hormone from fat cells, affects immune responses and can influence skin diseases and hair growth.

Eating a high-fat fish oil diet caused mice to lose hair due to a specific immune cell activity in the skin linked to a protein called E-FABP.

Researchers created human hair follicles using a new method that could help treat hair loss.

Vitamin D is important for skin health and may affect conditions like psoriasis and hair loss, but more research is needed to understand its role fully.
