Henrietta Lacks HeLa Cells The first immortal cell line
Cell culturing • For years scientists have been trying to grow human cells outside of the body. This could be used for research. • With no success. • When Henrietta went in for a biopsy they sent a piece of her tumor down the hall to the cell culture. • They didn’t die. They kept growing and multiplying. They are still alive today.
HeLa cellsAnonymity was important • These cells have been invaluable for medical research. • They’ve been used to create the polio vaccine • They were the first human cells to go up in space to see the effect of zero gravity • Vital in cloning • In vitro fertilization • Gene mapping
Now • Researchers learn the intricacies of how cells work and test theories about the causes and treatment of diseases. • HIV treatment • All our Vaccines • All our drug testing
Ethical Issues • No one told Henrietta that they took her cells. Anonymity is important for research. • The donor remained anonymous for 25 years. • These were the first human biological materials to be bought and sold. • The family is very poor and received no benefit. • The cells have contaminated other cultures so now they need to map the DNA of the family to help identify the cells.
