According to The Immortal life of Henrietta Lacks page 93-136. It tell us what happened to Henrietta since she was gone. In this part skloot describes how Hela cells were used to mass produce a polio vaccine, to develop reliable cell culture and cell storage methods, to develop clonal cell lines, to visualize human chromosomes, and to test new drug candidates, among many other breakthroughs.
We also learn about how the name Helen Lane was disseminated to hide the true identitu of Henrietta Lacks, a misunderstanding that persists to this day among many researchers. We also learn about the cavalier attitude of some physicians in this era, and specifically how a virologist named Chester Southam deliberately injected, without any consent, patients as well as Ohio state prisoners with Hela cells to see if they would form tumors in people-something that would be in conceivable today. In fact, Southam only stopped his human experiments when three physicians working for him at the Jewish Chronic desease Hospital refused to inject patients without consent because they believed it violated the Nuremberg code, established after the Nazis experimented on prisoners in concentration camps during World War II.
