Human skin can make serotonin and melatonin, which help protect and maintain it.

Stem cell niches are crucial for regulating stem cell behavior and tissue health, and their decline can impact aging and cancer.

Increasing mir-302 turns human hair cells into stem cells by changing gene regulation and demethylation.

The skin has a complex immune system that is essential for protection and healing, requiring more research for better wound treatment.

The document concludes that the understanding of scar formation is incomplete and current prevention and treatment for hypertrophic scars and keloids are not fully effective.

The conclusion is that using drugs to block the TOR pathway might slow aging and prevent age-related diseases.

Lichen Planus is a less common condition affecting skin and mucous membranes, with various types and associated risk factors, challenging to diagnose, significantly impacts life quality, and may have a risk of cancerous changes in oral lesions.

The secretome from mesenchymal stem cells is a promising treatment that may repair tissue and avoid side effects of stem cell transplantation.

Stem cell offspring help control their parent stem cells, affecting tissue health, healing, and cancer.

Melatonin in the skin helps protect against damage from stress and UV rays, and could be used to treat certain skin conditions.

Understanding where cancer cells come from helps create better prevention and treatment methods.

The conclusion is that proper signaling is crucial for hair growth and development, and errors can lead to cancer or hair loss.

The document provides a method to classify human hair growth stages using a model with human scalp on mice, aiming to standardize hair research.

Targeted cancer therapies often cause serious skin problems that need careful management.

Melatonin may benefit skin health and could be a promising treatment in dermatology.

Special fiber materials boost the healing properties of certain stem cells.

Certain inhibitors slow down plant growth by causing early cell specialization without changing the cell development pattern.

The document concludes that recognizing and treating cutaneous lupus erythematosus early is crucial for managing the skin and potential systemic symptoms.

Lichen planus is a skin condition that can resolve on its own, is linked to hepatitis C, and increases the risk of skin cancer.

Women with PCOS have a higher risk of diabetes and heart problems, especially when they get older.

Keratinocytes help heal skin wounds by interacting with immune cells and producing substances that kill pathogens.

Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.

Microneedles improve drug delivery in various body parts, are safe and painless, and show promise in cosmetology, vaccination, insulin delivery, and other medical applications.

Eating less sugar, milk, and saturated fats and more vegetables and fish may help treat and prevent acne.

Facial feminization surgery is effective in helping transgender women appear more feminine and has high patient satisfaction.

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.

Stress can stop hair growth in mice, and treatments can reverse this effect.

Cepharanthine is a well-tolerated drug with multiple medical uses, including anti-inflammatory and anti-cancer properties.

Targeting androgen receptors could be a promising way to treat skin disorders with fewer side effects.

MicroRNA-302 helps improve the conversion of body cells into stem cells by blocking NR2F2.
