Foreign media: Chinese scientists successfully repaired damaged external ears in mice, proving that organ regeneration is controlled by a specific gene "switch", and this mechanism may also exist in other organs.
The study was published in the authoritative journal "Science". The study points out that mice are unable to regenerate because of insufficient production of retinoic acid (a derivative of vitamin A) in their bodies, and retinoic acid is responsible for regulating cell types in development and tissue repair.
This discovery lays the foundation for achieving human organ regeneration.
