Researchers use HeLa cells to test nanotechnology, injecting them with iron nanowares and silica-coated nanoparticles.
Date 2005
Scientists expose HeLa cells to M. tuberculosis to learn how the disease attacks human cells.
Date 1993
A scientist at Yale University uses HeLa to discover that human cells contain telomerase, an enzyme that rebuilds a cell’s telomeres. The presence of this enzyme prevents HeLa cells from dying, making them immortal.
Date 1989
A molecular biologist named Richard Axel infects HeLa cells with HIV to study the virus' infection mechanism.
Date 1986
HeLa is used by a German virologist to help prove that the human papillomavirus (HPV) causes cancer.
Date 1984
Scientists use HeLa cells to better understand the invasiveness and infectiousness of salmonella and to study the behavior of salmonella inside human cells.
Date 1973
Scientists fuse HeLa cells with mouse cells and create the first cross-species hybrid. This genetic hybrid allows for advances to be made in the field of gene mapping.
Date 1965
In 1954, Chester Southam began to conduct experiments without patient consent to see whether or not injections of HeLa cells could cause cancer.

The Board of Regents of the University of the State of New York finds Southam and a colleague guilty of unprofessional conduct and calls for stricter guidelines regarding human research subjects and informed consent.
Date 1965
HeLa cells are sent into space in a Soviet satellite prior to the flight of any astronauts. NASA later includes HeLa cells in their first manned mission, and they discover that cancer cells grow faster in space.
Date 1960
HeLa cells become the first cells ever cloned. The early cloning technology that started because of HeLa cells led to many other advances that also necessitated the ability to grow cells in culture. Such advances included isolating stem cells, cloning entire animals,and in vitro fertilization
Date 1953
