chapter 13 and 17

In this chapter it provides an overview of what the cells were used for and how the production of them assisted in creating many different vaccines. It also goes on to say that the cells were used in many areas of research because the cells were easily reproduced and were attained very cheap. It also goes on to tell the reader how a factory was created using the hela cells and marketing them all over the world. It also tells us briefly about the various areas it is used from cosmetics to pharmacological testing.
How can standardization limit the research growth?
Why are standardization procedures so important to scientific research?
Did the microbiological have the right to grow and sell Hela cell's?
In chapter 17 we learn of a virologist named Chester Southham we learn that this dr infected cancer patents with hela cells to create more tumors by lying to the patients.  He used prisoners and it was documented he placed cells in a surgical gyno patient. The nih placed guidelines for research and patients after he was charged and found guilty of wrong doing.
Why was this allowed to go on?
Eventually there were guidelines and laws put into place but why did the dr get away with this and what was he charged with for his wrong doing? Did him and his colleagues go to jail?
