The protein causes the cells to remain pluripotent, meaning they can become any cell in the body, under conditions that would normally trigger them to develop into specialized cells.

The unexpected finding is likely to fan the flames of a millennia-old debate as to the regenerative power of royal jelly. More importantly, the discovery reveals new pathways to pluripotency and suggests novel ways to keep stem cells in a state of suspended animation until needed for future therapies.
