Ok here is a better answer, from a cbs article investigating the veracity of the claim that senomyx uses HEK 293 to test flavors
"Is this claim true? Neither Pepsi nor Senomyx returned calls, so we don’t know the companies’ side of the story. But a perusal of Senomyx’s patents suggests that it may well be. All but 7 of the company’s 77 patents refer to the use of HEK 293 (human embryonic kidney) cells, which researchers have used for decades as biological workhorses"
