An excerpt:
She aims to start with the gene Oct4 which appears to have a crucial role.
It is expressed only in a handful of blastocyst cells (pictured above in green) which go on to form all the tissues of the human body.
She will stop it functioning in 20-30 donated embryos and if the experiments are successful her research group will move on to other genes.
This means that she will kill 20 to 30 donated embryos after experimenting on them, and then move on to experiment with another two to three dozen embryos. How many hundreds of unborn embryos will die?
Lord have mercy.
