Some say gene editing shouldn’t be performed on human embryos until its effects are better understood.
The Huffington Post, By Sam Levine, September 18
The first British researchers have applied for permission to alter the DNA of human embryos to better understand the reason women have miscarriages, amid a broader debate over whether the testing is appropriate.
Earlier this year, Chinese scientists became the first in the world to modify human embryos. Researchers from the Francis Crick Institute are the first to seek permission to use the technique in Great Britain, where it is currently illegal except for research purposes.
The researchers hope to better understand the key genes involved in the first stages of fertilization and ultimately to determine the reason some women miscarry, according to The Guardian. The embryos, which are donated by couples who have a surplus after IVF treatment, would be destroyed after the research is completed. They cannot legally be studied for longer than two weeks.
