‘CRISPR Babies’ Lab Asked U.S. Scientist for Help to Disable Cholesterol Gene in Human Embryos
December 6, 2018
(STAT News) – The birth announcement made Musunuru dig out his old emails — which he shared with STAT — and do some sleuthing. The University of Pennsylvania researcher quickly found that the student, Feifei Cheng, worked with He and presented a paper written with him at a meeting on genome editing this past April in China sponsored by Cold Spring Harbor Laboratory. That paper reported editing PCSK9 in human, monkey, and mouse embryos. Re-reading the emails, Musunuru said he thinks it’s possible that embryos with the edited cholesterol gene were used in the second pregnancy.
