    HeLa Cells

    HeLa cells have been used to develop vaccines, and they have been exposed to radiation, cosmetics, drugs, cleaning supplies, viruses, and biological weapons. They helped create polio, HIV, and tuberculosis tests. HeLa cells have been used for many medical advancements, and they are still being used for research today!
  • Henrietta's Tissue Sample

    Henrietta's Tissue Sample
    George Gey extracted Henrietta's cells.
  • Cell Cultures Begin

    Cell Cultures Begin
    George Gey cultured Henrietta's cells successfully. They are now called HeLa Cells.
  • Death

    Death
    Henrietta Lacks died of cervical cancer. Her cells were extremely aggressive.
  • First Shipment

    First Shipment
    Henrietta's HeLa cells were shipped via mail. This was an extraordinary breakthrough for the science world because they were now able to easily receive the cells to research.
  • Tuskegee

    Tuskegee
    The Hela Factory is created at the Tuskegee Institute. The factory sent cells to labs and researchers.
  • Polio Vaccine

    Polio Vaccine
    Jonas Salk created the Polio Vaccine using HeLa cells. Salk used children's blood samples and mixed them with the HeLa cell cultures and the polio virus. He then looked at the results. Later, more HeLa cells were donated, so Salk was able to test and create the new polio vaccine to save thousands of lives.
  • Clones

    Clones
    HeLa Cells were cloned. Because of the cloning of Henrietta Lacks' cells, more medical advancements began. Different cells were able to be cultured, and this led to advancements in invitro fertilization.
  • Uninformed Injections

    Uninformed Injections
    In 1954, Chester Southam began injecting patients with HeLa Cells to discover how it would affect their bodies and whether or not the cells would cause cancer to form in the patients' bodies.
  • Animal-Human Hybrid Cells

    Animal-Human Hybrid Cells
    Scientists fused HeLa cells with mouse cells. This hybrid cross caused the possible advancement of field mapping.
  • Salmonella

    Salmonella
    Scientists studied HeLa Cells to understand salmonella. They were able to look at the effects of salmonella in human cells.
  • Finding Causes

    Finding Causes
    Harald zuh Hausen discovered how Henrietta's cancer started, and he discovered HPV-18. Using HeLa cells, he proved that HPV-18 causes cancer.
  • HIV Discoveries

    HIV Discoveries
    Richard Axel infected HeLa cells with HIV and discovered that HIV doesn't only infect blood cells. This lead to potentially discovering a way to stop HIV.
  • HeLa's Immortality

    HeLa's Immortality
    A scientist at Yale University used the cells and discovered that human cells have telomerase, an enzyme. The presence of the enzyme is what kept the HeLa cells from ever dying.
  • Tuberculosis

    Tuberculosis
    Scientists allowed HeLa cells and M. Tuberculosis cells to mix. This helped them learn how the tuberculosis cells attack the cells in humans.
  • Nanotechnology

    Nanotechnology
    Iron nanowares and nanoparticles were injected into HeLa cells to test nanotechnology.
