Their R&D analytical tests use HEK cells. They don't use the HEK cells in their products themselves as that would not make a lot of sense.
It's still horrible if you don't want human embryonic cells used in manufacturing but I think it's important for us to get the facts 100% right if we want people to listen to us.
