Certain proteins, Lgr5 and Lgr6, are important markers of adult stem cells and are involved in tissue repair and cancer development.

The immune system plays a key role in tissue repair, affecting both healing quality and regenerative ability.

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

Use minoxidil for hair loss; finasteride and dutasteride for men, dutasteride for women.

Visible light can damage skin and most sunscreens don't block it well; more research is needed on its effects and protection methods.

New effective scar treatments are urgently needed due to the current options' limited success.

Isotretinoin is highly effective in treating severe acne, rosacea, and gram-negative folliculitis.

Some medicinal plants can help heal wounds and may lead to new treatments.

Fibromodulin might help reduce scarring if increased in adult wounds like in fetal skin that heals without scars.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

Nanoparticles improve drug delivery through the skin but more research is needed on their long-term effects and skin penetration challenges.

Liposomal systems show promise for delivering drugs through the skin but face challenges like high costs and stability issues.

Silver can help prevent and treat infections but its effectiveness varies and should be weighed against costs and side effects.

The document concludes that accurate diagnosis of ichthyosis is crucial for treatment and genetic advice, and ongoing research is needed for better therapies.

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

The document concludes that a better understanding of cell changes during wound healing could improve treatments for chronic wounds and other conditions.

Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.

PRP treatment improves hair growth, and the device used can affect results, with some being more effective.

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

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

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.

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.

Isotretinoin effectively treats severe acne and similar conditions, but has common, mostly reversible side effects, requiring careful patient monitoring.

Understanding how cells die in the skin is important for treating skin diseases and preventing hair loss.

Platelet-rich plasma might help with hair growth and skin conditions, but more research is needed to prove its effectiveness and safety.

Treatments for permanent hair loss from scarring aim to stop further loss, not regrow hair, and vary by condition, with partial success common.

Nanoparticles can improve skin treatments by better targeting hair follicles, but more research is needed for advancement.

Iranian veterans exposed to sulfur mustard suffer from long-term skin itching and eye damage, with some risk of skin cancer and ongoing management challenges.

The Wnt/β-catenin pathway helps tissue regeneration but can also cause fibrosis, and drugs that inhibit this pathway may aid in healing skin and heart tissues.
