Chitin and chitosan are useful in cosmetics for oral care, haircare, and skincare, including UV protection and strength improvement.

Microtechnology methods improve organoid production for medical research.

Eph receptors and ephrins may be promising targets for treating diseases, but more understanding is needed for effective and safe therapies.

Genetic factors influence hair traits like shape, color, and greying in Latin Americans.

Researchers found 19 genes important for root hair growth in a plant called Arabidopsis.

Epigenetic changes control how adult stem cells work and can lead to diseases like cancer if they go wrong.

K_ATP channel gene mutations are linked to heart diseases, but more research is needed to understand the connection and treatment potential.

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.

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

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

The document concludes that understanding hair structure is key to diagnosing hair abnormalities and recommends gentle hair care for management.

Stress can cause hair loss by negatively affecting hair follicles and this effect might be reversed with specific treatments.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

Epidermal β-catenin activation changes the dermis by signaling different fibroblast types.

Stress increases nerve fibers and immune cell activity in mouse skin, possibly worsening skin conditions.

C60 fullerenes can alter protein function and may help develop new disease inhibitors.

Cepharanthine and Trifluoperazine are effective against SARS-CoV-2.

Mutant CDP/Cux protein causes hair defects and reduced male fertility in mice.

The p75 neurotrophin receptor is important for hair follicle regression by controlling cell death.

Turing patterns are now recognized as important in developmental biology.

Human epidermal neural crest stem cells can become bone and skin pigment cells, making them useful for therapies.

Activin helps skin growth and healing mainly through stromal cells and affects keratinocytes based on its amount.

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

Human skin cells produce proenkephalin, which changes with environmental factors and skin diseases.

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.

Certain mice without specific receptors or mast cells don't lose hair from stress.

Targeting the skin's endocannabinoid system could help treat skin disorders.

Mushrooms have beneficial properties for skin and hair care products and have great potential for future cosmetic use.

Engineered exosomes show promise for improving wound healing but face challenges in clinical use.

Human hair follicles produce and respond to erythropoietin, helping protect against stress.
