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

The PDGF/PDGFR pathway is a potential drug target with mixed success in treating various diseases, including some cancers and fibrosis.

Regenerated fully functional hair follicles using stem cells, with potential for hair regrowth therapy.

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

Myrtle has various health benefits and potential for medicine development.

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.

Stem cell niches support, regulate, and coordinate stem cell functions.

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

Early development of hair, teeth, and glands involves specific signaling pathways and cellular interactions.

Blocking JAK-STAT signaling can lead to hair growth.

Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

Tight junctions are key for skin protection and controlling what gets absorbed or passes through the skin.

Memory T cells in the skin balance staying put and moving into the blood, clustering around hair follicles, and increasing in number after infection.

Understanding hair growth involves complex interactions between molecules and could help treat hair disorders.

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.

Alopecia areata is an autoimmune disease causing patchy hair loss, often with other autoimmune disorders, but its exact causes are unknown.

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

Hair follicles may soon be used more for targeted and systemic drug delivery.

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

Transplant success has improved with better immunosuppressive drugs and donor matching.

Periodontal ligament stem cells show promise for regrowing tissues but require more research for safe, effective use.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Low oxygen conditions increase the hair-growing effects of substances from fat-derived stem cells by boosting growth factor release.

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

Nanoparticles can improve skin drug delivery but have challenges like toxicity and stability that need more research.

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.

PEVs improve minoxidil skin penetration, increasing hair growth.

Men generally have more severe COVID-19 cases and higher death rates than women due to biological differences.
