Chinese scientists have implanted human brain genes into monkeys, taking another step into what has been described as the “ethical nightmare” realm of gene-editing.
In a study published last month in Beijing’s National Science Review, the journal of the state-sponsored Chinese Academy of Science, scientists inserted the human gene, MCPH1, which has been linked to brain development, into 11 monkey embryos via a virus which carried the gene into the monkeys’ brains.
