Double time limit for embryo research, say ethics experts

Science News
August 7, 2018

Currently, research on embryos is limited in many countries to a maximum period of 14 days after their fertilisation in the lab.

But ethicists Dr John Appleby of Lancaster University with Professor Dr Annelien Bredenoord of University Medical Center Utrecht believe the current limit is "no longer adequate for current scientific developments."

Dr Appleby and Professor Dr Bredenoord said: "The 14 day rule has been a very successful example of international science regulation, but it should not become a dogma in itself and it should be revisited when no longer fit to purpose."

Until recently, scientists have not been able to culture and sustain embryos in vitro as long as (or beyond) 14 days but this has now changed.

"There are both scientific and ethical reasons to extent the 14 day rule to for example 28 days. Extending the window for embryo research to 28 days would allow scientists to reveal a new in-depth chapter of knowledge about the developmental processes that take place in embryos."
