Meanwhile, Victor McKusick and Susan Hsu had just published the results of their research in Science: in a table that took up about half of a page, under the headings “Husband,” “Child 1,” “Child 2,” “H. Lacks,” and “HeLa,” McKusick, Hsu, and several coauthors mapped forty-three different genetic markers present in DNA from Day and two of the Lacks children, and used those to create a map of Henrietta’s DNA that scientists could use to help identify HeLa cells in culture.
