Using an egg and a stem cell, researchers at the Chinese Academy of Sciences. manipulated the DNA of two mice to give birth to babies that had two mothers.
The “bimaternal” mice were healthy, but bipaternal experiments yielded babies that died shortly after birth. Researchers say there is no near term application in humans, and that even the mouse model requires further study.
Prof Robin Lovell-Badge at the Francis Crick Institute told the BBC: “Even with two mothers I’m not convinced they’re normal and the success rate is pretty low”.
