So much I did not know about Hela !!

History does teach us a lot ! Hela cells were used to find Polio vaccination, used to Tuskegee syphilis study, learned about spontaneous transformation. Not only scientists figured out how to freeze the cells, they were able to come up with the process of shipment cells and the standardize culture medium while keeping them alive and viable. When George Otto Gey first started, could he ever imagine how much is going to change in the history of science working on those cancerous cells collected from Henrietta's cervix?
