VERIFY: Was the antibody cocktail used to treat President Trump developed using human embryonic stem cells? – CBS News 8

Social media is buzzing with the claim President Trump, who is pro-life, used an antibody cocktail developed using human embryonic stem cells.

The antibody cocktail used to treat President Donald Trump for COVID-19 is getting a lot of attention on social media.

Some users are claiming Regeneron - the company that developed the treatment - used human embryonic stem cells to create it, but is this true?

News 8 reached out to Regeneron for comment.

"This particular discovery program (regn-cov2) did not involve human stem cells or embryonic stem cells," wrote Regeneron spokesperson Alexandra Bowie in a statement.

So, where did that claim about human embryonic stem cells come from?

It appears to have developed from this statement Regeneron issued back in April 2020 regarding stem cell research:

"As is the case with many other science-focused biotechnology companies, Regeneron uses a wide variety of research tools and technologies to help discover and develop new therapeutics. stem cells are one such tool. the stem cells most commonly used at Regeneron are mouse embryonic stem cells and human blood stem cells. currently, there are limited research efforts employing human-induced pluripotent stem cell lines derived from adult human cells and human embryonic stem cells that are approved for research use by the national institutes of health and created solely through in vitro fertilization."

According to the American Association for the Advancement of Science, here's what the antibody cocktail used to treat the president is made of:

"One antibody comes from a human who had recovered from a SARS-COV-2 infection; a B cell that makes the antibody was harvested from the person's blood and the genes for the immune protein isolated and copied. The other antibody is from a mouse, which was engineered to have a human immune system, that had the spike protein injected into it."

Bowie also told News 8 the statement about stem cell research on its website reflects the company's general position on stem cell research, but does not mean human embryonic stem cells were used in creating the antibody cocktail used to treat the president.

Nevertheless, some said the company's position on using stem cells in general contradicts President Trump's pro-life stance and that of Supreme Court Nominee Amy Coney Barrett.

But the bottom line, were human embryonic stem cells used in Regeneron's antibody cocktail to treat the president? News 8 can verify the answer is no.
