Cross-Disciplinary Research on Ethylene in Plant and Mammalian Stem Cell Responses

Ethylene (C2H4) is a primary phytohormone that plays a crucial role in plant cell regeneration and wound healing. Although it is not produced endogenously within the human body, researchers are exploring its indirect application potential in mammalian stem cells. For instance, ethylene can serve as an exogenous gas to simulate oxidative stress, prompting stem cells to express antioxidant factors and repair genes. This cross-species signaling research offers significant inspiration for developing novel gaseous therapies in regenerative medicine. While current applications remain in the experimental stage, the cellular regulatory potential of ethylene warrants continued attention.
