New treatments for skin damage from UV light using stem cells and their secretions show promise for skin repair without major risks.

Sex hormones may affect COVID-19 severity, with estrogen possibly reducing risk and testosterone potentially increasing it.

New regenerative techniques show promise for improving skin, healing wounds, and growing hair.

Tiny vesicles from stem cells could be a new treatment for healing wounds.

Fire needle therapy is an effective and better alternative to surgery for early-stage neck carbuncles.

Wnt signaling is crucial for skin development and hair growth.

The new method for isolating stem cells from fat is simple and effective, producing cells that grow faster and are better for hair regeneration.

Scientists made stem cells that can grow hair by adding three specific factors to them.

The Multi-Organ-Chip improves the growth and quality of skin and hair in the lab, potentially replacing animal testing.

Minoxidil boosts hair growth by triggering growth factor release from specific stem cells.

Low-dose UVB light improves hair growth effects of certain stem cells by increasing reactive oxygen species.

ADSC-CE treatment safely increases hair density and thickness in androgenetic alopecia patients.

Tissue expansion is an effective treatment for certain types of hair loss, providing immediate coverage with hair-bearing skin.

Fat-derived stem cells can help protect and repair skin stem cells from aging caused by UV light.

Using fat stem cells and blood cell-rich plasma together improves healing in diabetic wounds by affecting cell signaling.

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

Asia has made significant progress in tissue engineering and regenerative medicine, but wider clinical use requires more development.

New findings explain how genetic changes, body clocks, and certain molecules affect tissue response to stress hormones.

Using fat-derived stem cells for hair loss treatment is safe and effective, improving hair growth and patient satisfaction.

Stem cells help repair tissue mainly by releasing beneficial substances, not by replacing damaged cells.

SCDSFs from zebrafish embryos are beneficial for treating cancer, regenerating tissues, and improving conditions like psoriasis and alopecia.

The document concludes that skin grafts are essential for repairing tissue loss, with various types available and ongoing research into substitutes to improve outcomes and reduce donor site issues.

People in Jeddah know about Vitamin D and its sources but are unclear on how much they need daily, and while many women take supplements, attitudes towards increasing Vitamin D levels vary.

Testosterone implants in women require pharmacological dosing to be effective and are generally safe and well-tolerated.

New treatments for hair loss show promise, including plasma, stem cells, and hair-stimulating complexes, but more research is needed to fully understand them.

Hormonal changes and psychological issues can cause sexual dysfunction in postmenopausal women. Behavioral therapy is recommended first, with hormone replacement helping some symptoms but not libido. Testosterone can improve libido, but its effects on overall sexual function are unclear. Emotional and relationship issues should be addressed before using medication, and the benefits and risks of testosterone supplementation should be considered.

The secretions of mesenchymal stem cells could be used for healing without using the cells themselves.

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