cervical carcinomas are divided into two types; invasive and noninvasive. HeLa cells proved that carcinoma in situ needed aggressive treatment so their cancer doesn't become invasive. create Hela lab to mass-produce her cell and made a medium to grow it in
1952 - 1953
Enabled researchers to see and count each chromosome clearly in the HeLa cells they were working with. HeLa cells were used to discover virology where they would continuously infect the HeLa cell with viruses
HeLa cells are found to be an effective tool for growing large amounts of poliovirus. The high amount of virus that can be grown in HeLa cells allow scientists to better understand how the virus infects cells and causes disease
HeLa cells are used by scientists to develop a cancer research method that tests whether a cell line is cancerous or not.
Scientists use HeLa cells to determine how radiation can damage cells.
outer space and hybrids
1964 - 1965
HeLa cells are taken aboard some of the very first capsules used to explore outer space. These studies provide initial clues to how human cells will react to radiation and how space travel may impact astronauts in future manned missions.
mice were infused with HeLa cell creating the first human-animal hybrid that helped map human genes
Hela cells help to determine the effects of salmonella in human cells and gauge its infectiousness
HPV and HIV
1985 - 1986
The discovery that HPV can lead to cervical cancer. By using HeLa scientist discovered a key receptor in the HIV virus
HeLa cells shows that the telomerase enzyme produces “caps” on the ends of DNA chromosomes that prevent them from degrading over time.
Scientists use HeLa cells to see for the first-time, at the molecular level, how tuberculosis makes people sick.
