Scientists May Be Using the Wrong Cells to Study Covid-19

August 7, 2020

(Wired) – By now there’s little doubt about hydroxychloroquine: It doesn’t work for treating Covid-19. But there’s a bigger, more important lesson hidden in the story of its failure—a rarely mentioned, but altogether crucial, error baked into the early research. The scientists who ran the first, promising laboratory experiments on the drug had used the wrong kind of cells. Instead of testing its effects on human lung cells, they relied on a supply of mass-produced, standardized cells made from a monkey’s kidney. In the end, that poor decision made their findings more or less irrelevant to human health. Worse, it’s possible that further research into novel Covid-19 cures will end up being compromised by the same mistake.
