Scientists smash record for human embryos grown in the lab in revolutionary breakthrough



Since scientists first fertilised an embryo in a test tube in 1969, they have never managed to keep one alive for long after the point at which the foetus implants in the womb, normally about seven days. 

However researchers at Cambridge University have now grown embryos for 13 days — a process they only stopped to avoid breaking the current legal limit of about 14 days. 

The ability to observe a human embryo as it grows during this “most enigmatic and mysterious” stage of life in a lab should shed new light on genetic diseases and disabilities.

And it could help improve the dismal failure rate of IVF embryos — currently up to 70 per cent do not successfully implant – and lead to better understanding of miscarriages.
