Hair and skin can regenerate without bulge stem cells due to other compensating cells.

Skin health and repair depend on the signals between skin stem cells and their surrounding cells.

An 80-year-old patient grew new hair on a wound, showing that elderly people can still regenerate hair.

Scientists have improved 3D models of human skin for research and medical uses, but still face challenges in perfectly replicating real skin.

Fat cells are important for tissue repair and stem cell support in various body parts.

T-regulatory cells are important for skin health and can affect hair growth and reduce skin inflammation.

Fat-derived stem cells show promise for treating skin issues and improving wound healing, but more research is needed to confirm the best way to use them.

Skin cells and certain hair follicle areas produce hemoglobin, which may help protect against oxidative stress like UV damage.

Leptin, a hormone from fat cells, affects immune responses and can influence skin diseases and hair growth.

ILK is essential for proper hair follicle development and structure.
