The Curious Contamination

Scientists knew that it was important to keep their cultures free of contamination, but "when it came to HeLa, they had no idea what they were up against. It turned out Henrietta's cells could float through the air on dust particles" (Skloot 153).

When geneticist Stanley Gartler, learned the racial origin of HeLa from Dr. Gey, it went on to create a huge effect in the scientific community. His discovery helped to show that it was in fact possible for cells to travel to other cultures very quickly. He was able to understand this process because of a rare genetic marker known as, G6PD-A which was only ever present in black Americans (Skloot 153). The HeLa cells were shown to transfer by unwashed hands, lab coats, shoes, and also research found that if just a single cell was to land on a different culture dish, it was strong enough to consume all that was there (Skloot 153). This finding by Dr. Gartler was presented at a conference which was not accepted with positive review because it meant that over a decade, scientists had spent millions of dollars on scientific research with only HeLa cells. This meant that all the time and effort spent growing and experimenting on the cells was a waste. After his discussion at the Cell Culture Collection Committee meeting, numerous scientists went back to their laboratories to test cells for the genetic marker to find out how big this problem could be. The overall factor across the world many of the cells tested positive with G6PD-A and this mass contamination became known as “the HeLa bomb” (Skloot 156).

The Incredible Advances In Scientific Development

"Not long after Henrietta's death, planning began for a HeLa factory- a massive operation that would grow to produce trillions of HeLa cells each week. It was built for one reason: to help stop polio." (Skloot, 92)

It is incredible how quickly cells can grow in a matter of weeks. To be able to produces trillions of HeLa cells from a sample taken from Henrietta is an outstanding number. Scientific research has come a long way since the largest polio epidemic in 1951. This was a frightening time for millions of families because there was a drastic need for a vaccine. During this time period “scientists were just beginning to understand viruses, so as Henrietta’s cells arrived in labs around the country, researchers began exposing them to viruses of all kinds.” (Skloot, 98) Her cells helped to create a huge difference in the scientific field. Numerous improvements were made especially regarding the topic of freezing cells without causing harm. This was a breakthrough because it allowed her cells to successfully transfer from one country to another without an alteration. It was known that HeLa was also being used in the field of human genetics, and as all of these developments kept progressing, the request for HeLa rose. I think it is incredible that Henrietta’s sample created such a spark in scientific research. The impact her cells have made to science has truly saved so many lives.
