Hormones cause hair loss by affecting cell growth and weakening cell attraction.

The document concludes that while some organisms can regenerate body parts, mammals generally cannot, and cancer progression is complex, involving mutations rather than a strict stem cell hierarchy.

Different types of fibroblasts play various roles in diseases and healing, and more research on them could improve treatments.

The right cells and signals can potentially lead to scarless wound healing, with a mix of natural and external wound healing controllers possibly being the best way to achieve this.

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

Diazoxide, minoxidil sulphate, and cromakalim relax rat blood vessels by opening K+ channels, with some differences in their actions.

Lamins are vital for cell survival, organ development, and preventing premature aging.

Baricitinib reduces inflammation and improves cell health in premature aging cells.

Severe vertex pattern hair loss may indicate a higher risk for artery plaque buildup.

Different types of fibroblasts play various roles in kidney repair and aging, and may affect chronic kidney disease outcomes.

Collagen-enhanced mesenchymal stem cells significantly improve skin wound healing.

Using mesenchymal stem cells or their exosomes is safe for COVID-19 patients and helps improve lung healing and oxygen levels.

Stem cells and their exosomes show promise for repairing tissues and healing wounds when delivered effectively, but more research is needed on their tracking and optimal use.

Nitric oxide is important for skin functions and both helps protect against and contributes to skin inflammation and sensitization.

The new microwell device helps grow more hair stem cells that can regenerate hair.

Steroid hormones can help treat aging issues and improve health in elderly people.

Nandrolone decanoate damages the heart, liver, and kidneys.

Stem cells from whiskers can be transplanted to stimulate hair growth.

PRP may help hair growth in alopecia areata without major side effects, but more research is needed.

Advancements in tissue engineering show promise for hair follicle regeneration to treat hair loss.

The document concludes that better targeted treatments are needed for wound healing, and single-cell technologies may improve cell-based therapies.

Skin-derived precursors in hair follicles come from different origins but function similarly.

Electrospun nanofibers show promise for enhancing blood vessel growth in tissue engineering but need further research to improve their effectiveness.

Keratin proteins are crucial for healthy skin, but mutations can cause skin disorders with no effective treatments yet.

TGFβ signaling prevents sebaceous gland cells from producing fats.

Damaging mitochondrial DNA in mice speeds up aging due to increased reactive oxygen species, not through the p53/p21 pathway.

Gene therapy shows promise for enhancing physical traits but faces ethical, safety, and regulatory challenges.

Skin-derived stem cells grow faster and are easier to obtain than hair follicle stem cells, but both can become various cell types.
