Washington D.C., Aug 2, 2017 CNA/EWTN News.- Researchers in Oregon have announced that they have successfully altered genes in a human embryo for the first time in the United States, but Catholic ethicists warn that the procedure was morally objectionable for many reasons.

“Very young humans have been created in vitro and treated not as ends, but as mere means or research fodder to achieve particular investigative goals,” said Fr. Tadeusz Pacholczyk, Director of Education for the The National Catholic Bioethics Center, in a statement to CNA.

“Their value as human beings is profoundly denigrated every time they are created, experimented upon, and then killed. Moreover, if such embryos were to grow up, as will doubtless occur in the future, there are likely to be unintended effects from modifying their genes,” Fr. Pacholczyk continued.

A team of scientists led by Shoukhrat Mitalipov at Oregon Health and Science University announced this week that they used a technology known as CRISPR to edit sections of the human genome, performing the procedure on embryonic humans. The technology, which selectively “snips” and trims areas of the genome and replaces it with strands of desired DNA, has previously been used on adult humans and other species.
