Still, many scientists refused to believe HeLa contamination was real. After the conference where Gartler dropped what became known as “the HeLa bomb,” most researchers kept right on working with the cells he’d said were contaminated. But Stevenson and a few other scientists realized the potential scope of the HeLa contamination problem, so they began working to develop genetic tests that could specifically identify HeLa cells in culture instead of just testing for the presence of G6PD-A. And those genetic tests would eventually lead them to Henrietta’s family.
