Fiona Watt finished her thesis research in record time. It was the late 1970s, and Watt had joined the lab of Henry Harris at Oxford University. Harris had perfected a method for fusing normal cells with cancer cells, an approach that allowed him to look for molecules that prevented the abnormal growth of the resulting hybrid. “When I first went to see Professor Harris, he told me, ‘There are only two intellectually important problems: cancer and differentiation,’” says Watt. “Of course, I agreed—and still do! Then he asked, ‘Which do you want to work on?’ I said, ‘Differentiation.’ So he gave me cancer.”
At the time, Harris had compiled a list of potential molecular markers for cancer cells. His students were working their way down ...
