HeLa Cells In Space
36
The Results
After many missions, and many experiments scientist came to a conclusion.
- In zero gravity the HeLa cells divided more quickly
- When the cells went into orbit, they became much stronger and divider faster with each trip
- Noncancerous cells grew normally
Who and When
- 1968- Russia launched the Vostok 4 (The 2nd Russian Satellite ever)
- On board was a sample of HeLa cells
- Russia was the first to send HeLa to space
- NASA was the second
After the discovery
After this discovery, scientist began noticing something in all cultured cells.
- They all died or became cancerous
- They divided identically and produced the same proteins and enzymes
- They discovered all cultured cells were contaminated by HeLa
The Mission(s)
Scientist sent HeLa cells into space to test the effects of
- Zero Gravity
- It going into orbit
They sent up cancerous and noncancerous cells to see the difference
The Question
Good and Bad
"What effect does space environment have on cells and tissues?"
These results were good for some, but disturbing for others.
Good: This information allowed scientist to study the moment cells become malignant.
Bad: This was bad for scientist using cell structure to develop medical therapies.
This is the question scientist asked, and they used HeLa cells to get their answer.
What are HeLa Cells
- The first human cells grown in a lab
- They were immortal and continue to grow to this day
- A doctor named George Gey took samples from a women with cervical cancer
- Her name was Henrietta Lacks, which is where the name HeLa came from

Other Experiments
- Exposed to different types of Radiation
- Exposed to toxins
- To detect DNA damage caused by space radiation
- To study the nutritional needs of cells in space
HeLa Cells In Space
Overall
- HeLa cells were the first cells to go into space
- Space travel, nutritional needs of cells in space, and how cancerous and noncancerous cells respond differently to the space enviroment
- All of their discoveries have contributed to the knowledge scientist have of the effects of space travel on cells, tissues and humans.
