Scientists have made progress in creating replacement teeth, hair, and glands that work, which could lead to new treatments for missing teeth, baldness, and dryness conditions.

Somatostatin may help protect hair follicles from immune attacks.

Mesenchymal stem cells, especially injected into the skin, heal wounds faster and better than chitosan gel or other treatments.

Over 50% of women over 50 experience hair loss, with minoxidil being the only proven effective treatment.

A substance called Vascular Endothelial Growth Factor can protect certain hair follicle stem cells from damage caused by androgens, suggesting a new possible treatment for hair loss.

Active oxygen species might be involved in skin tumor growth, but their exact role is unclear.

Melatonin receptors in hair follicles help regulate hair growth and could treat hair loss.

AGA treatments like minoxidil and LLLLT are safe and effective for gender minority patients.

Current therapies cannot fully regenerate adult skin without scars; more research is needed for scar-free healing.

The "Punch Assay" can regenerate hair follicles efficiently in mice and has potential for human hair regeneration.

The research found that the gene activity in mouse skin stem cells changes significantly as they age.

Dermal papilla microtissues could be useful for initial hair growth drug testing.

Root hairs in maize grow mainly in air-filled pores, limiting their role in nutrient uptake and plant anchorage.
