Different types of skin cells play specific roles in development, healing, and cancer.

Jumonji genes are important for development and their mutations can cause abnormalities, especially in the heart and brain.

The document concludes that more research is needed to better understand and treat primary cicatricial alopecias, and suggests a possible reclassification based on molecular pathways.

Environmental factors, hormones, nutrition, and stress all significantly affect skin health and aging.

There is no clear recommendation for using selenium in cancer patients; it may be beneficial to correct low selenium levels before treatment.

Activating NRF2 might help treat hair disorders by improving antioxidant defenses.

Combining cosmetic procedures with lifestyle changes improves antiaging results.

UVB radiation changes the levels of certain microRNAs in skin cells, which may affect cell survival and hair growth.

The study found that expanded skin regenerates similarly to normal skin, with 77 genes playing a role in the process.

Vitamin D made by the skin plays a role in immune defense and skin health, and more research is needed to understand its full effects.

PRP shows promise for skin rejuvenation but needs more research.

Targeting specific miRNAs may help treat hair follicle issues caused by hydrogen peroxide.

Recombinant human epidermal growth factor is versatile, effective, and safe for long-term skin and mucosal treatments.

Mitochondrial therapy and platelet-rich plasma therapy both stimulated hair regrowth in aging mice, with mitochondrial therapy showing similar effectiveness to plasma therapy.

Aging skin shows thinner layers, fewer hair follicles, and new biomarkers like increased space between cells and smaller sebaceous glands.

KLF4 is important for maintaining stem cells and has potential in cancer treatment and wound healing.

Compression therapy improved ankle movement, reduced leg swelling, and lessened pain in patients with venous leg ulcers.

The cornified envelope is crucial for skin's barrier function and involves key proteins and genetic factors.

Chemicals and stem cells combined have advanced regenerative medicine with few safety concerns, focusing on improving techniques and treatment effectiveness.

Mice without the vitamin D receptor have bone issues and other health problems, suggesting vitamin D is important for preventing various diseases in humans.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

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 fast-growing direct-to-consumer genetic testing market lacks sufficient regulation, posing risks to consumers due to questionable test quality and accuracy.

Aging causes skin stem cells to work less effectively.

The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.

Certain genes control the color of human hair by affecting pigment production.

Hair grays due to oxidative stress and fewer functioning melanocytes.

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.

Scientists have created a new hair loss treatment using ultrasound to deliver gene-editing particles, which resulted in up to 90% hair regrowth in mice.
