Yes they only used the Embryonic kidney cells EKC for development, they must have grown them and use them, I don't see the point if they don't duplicate the cells from the 1970s baby they used. Coke uses insects and a different company, A shareholder wrote a letter to Pepsico asking them not to use human sources. It's a bitterness suppressor that they could use plant or insects for, why they chose this IDK but maybe because they could get a patent on it but it's illegal to get a patent on a human for just that reason.
