*More were successfully fertilised (43 out of 50, compared with 41 out of 50).
*More developed to the stage at which they could be implanted into a real mother (35 out of 50 compared to 32 out of 50).
*They grew faster (containing around 77-119 cells compared to 58-94 cells, after 2 days).
*More continued to develop when implanted into female mice (44% compared to 40%).
Dr Wheeler commented: 'It's not just about more embryos surviving to be implanted...They also seem to be doing better once they are implanted'.
Following these successful experiments in mice, Fuji's team have now been granted permission to begin trails on human embryos later this year.
