The details of HEK293’s brutal – and from all appearances, until very recently, largely undisclosed – origins explain the company’s deep discomfort. Contrary to nearly a half-century of misrepresentation and obfuscation, HEK293’s creation did NOT arise from an “abortion” as everyday people understand it.

To harvest a viable embryonic kidney … sufficiently healthy children old enough to have adequately-developed kidneys must be removed from the womb, alive, typically by cesarean section, and have their kidneys cut out. This must take place without anesthesia for the child, which would lessen the viability of the organs.
