Radiation mainly affects keratinocyte stem cells, not melanocyte stem cells, causing hair to gray.

The review found that different stem cell types in the skin are crucial for repair and could help treat skin diseases and cancer.

A specific group of slow-growing stem cells marked by Thy1 is crucial for skin maintenance and healing in mice.

Older hair follicle stem cells have a reduced ability to renew themselves, leading to more hair loss.

Stem cells regenerate tissues and their behavior varies by environment, suggesting the hematopoietic system model may need revision.

Stem cells help heal skin wounds by moving and changing roles, working with other cells, and needing more research on their activation and behavior.

Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.

KLF4 is important for maintaining stem cells and has potential in cancer treatment and wound healing.

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.
