Capsaicin, found in chili peppers, can slow down hair growth by affecting skin cells and hair follicles.

Wnt signaling controls whether hair follicle stem cells stay inactive or regenerate hair.

Epidermal stem cells are diverse and vary in activity, playing key roles in skin maintenance and repair.

Hormone treatments for transgender individuals generally improve mental health and physical transition, with some health risks that require medical supervision.

Scientists made working salivary glands in mice using bioengineered cells, which could help treat dry mouth.

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.

Blocking COX, especially COX-2, in the skin can reduce inflammation and pain and may help prevent skin cancer.
