Her immortal life had made a great contribution to the human health scientific research.

However, when go back to the book, there is a sad truth. Henrietta would never know that a piece of tissue was cut off from her body and been used to all kinds of medical research. It is sarcastic that Henrietta's cell save many people's life, but as a poor mother, her death never brought any benefit to her family, her family even did not know HeLa cell until decades, and her children had a really hard childhood. [Reb10] With the help of HeLa cells, medical science advanced rapidly in recent decades. And it is understandable that scientists want to use human tissue to overcome medical problem.

Racial disparities persisted even after restricting the analysis to patients who had physician access before their diagnosis.[Gar08] What is more, another research "Attitudes and Beliefs of African Americans Toward Participation in Medical Research  shows African-American participants in the study described distrust of the medical community as a prominent barrier t
