A statement misconstrued Alexandra Bowie of Regeneron told news aggregation platform Heavy in an October email that REGN-COV2 was not made with human embryonic stem cells. "This particular discovery program (REGN-COV2) did not involve human stem cells or ESCs," Bowie wrote. The statement shared on Twitter is simply Regeneron's official position on stem cell research in general and bears no relation to, or explanation of, how REGN-COV2 is made. Bowie also confirmed this with Heavy. https://www.usatoday.com/story/news...therapy-not-made-fetal-stem-cells/5901542002/
