Answer these two questions about the Immortal Life of Henrietta Lacks

I’m working on a science writing question and need an explanation and answer to help me learn.

1. What role did the deferential attitude toward doctors in the early 20th century play in the interaction between Henrietta and her family and Johns Hopkins? How has that attitude toward doctors changed over the decades? Do patients’ socioeconomic differences affect the relationship today? 

2. In the years since the uniqueness of Henrietta Lacks’s cells were discovered, others have been identified with cells that are valuable on the research market. In Chapter Five, Skloot details the history of John Moore, whose cells produced rare proteins, and Ted Slavin, whose cells produced valuable antibodies. All three cases are quite different in many ways, including how their doctors used the information. Should individuals be able to profit from their own cells? Should their doctors? With consent?
