WHY ARE HENRIETTA LACKS 

CELLS SO IMPORTANT?

These cells are so important because and they've been mentioned lots of times, more than 70000 times since they were discovered in 1951 because they are the first human inmortal cells ever grown in the world.
One of the most strange thing about this cells is that they were extracted from a black woman without her knowledge, but they were extracted from a cancerous tumor she had. These cells were extracted and cultivated by George Otto Gey.
But this cells are also important for scientists because it was essemtial to developing the polio vaccine, they went up to the space in the first space missions to see what would happen to cells in zero gravity, contributed to the developments of drugs for herpes, leukemia, influenza and Parkinson's disease. and help in many scientific landmarks, like cloning,gene mapping and vitro fertolisation.
Henrietta Lacks was a tobacco farmer from southern Virginia who got cervical cancer when she was 30. A doctor at Johns Hopkins took a piece of her tumor without telling her and sent it down the hall to scientists there who had been trying to grow tissues in culture for decades without success. No one knows why, but her cells never died.
