  3. Zielinski explains how the first immortal human cells were found then provides Rebecca Skloot’s answers to  questions about the importance of using human tissue samples, the Lacks family’s responses to learning of its  link to the HeLa cells, and the issues arising from their discovery and use.
  4. Zielinski explains the importance of the first human tissue samples to life and their widespread use, the  reason for the confusion about those samples as well as the ethical issues faced by the Lacks family after learning they had not shared in profits from the sale of the HeLa samples.
