Three types of stem cells help maintain and repair skin, responding to health and environmental changes.

Human hair follicle stem cells can grow and turn into skin cells on chitosan templates, which may help in regenerative medicine.

Fat tissue-derived cells show promise for repairing body tissues, but more research and regulation are needed for safe use.

Keratin from human hair shows promise for medical uses like wound healing and tissue engineering.

The Wnt/β-catenin pathway helps tissue regeneration but can also cause fibrosis, and drugs that inhibit this pathway may aid in healing skin and heart tissues.

Epithelial stem cells can adapt and help in tissue repair and regeneration.

Skin cysts might help advance stem cell treatments to repair skin.

Human scalp hair follicles grow well in Williams E medium, which may help with hair transplants.

Changing light periods synchronized wool growth cycles in sheep.

A specific molecular switch, driven by MAPK/ERK signaling, helps spiny mice heal wounds by regenerating skin instead of forming scars.

Regenerative pharmacology, which combines drugs with regenerative medicine, shows promise for repairing damaged body parts and needs more interdisciplinary research.

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

Keratin extract from human hair was found to promote hair growth in mice.

The gp130 receptor helps in tissue regeneration and disease progression, and manipulating it could improve healing and prevent disease.

Ptch2 plays a key role in controlling stem cell function and the ability to regenerate after birth.
