How was Gartler able to link the contamination problem to HeLa? He was able to link
because Gey told him that HeLa came from a black woman and this component was almost exclusive present just in black Americans
. … HeLa cell could float through the air on dust particles.
What did Stanley Gartler discover about HeLa cells?
Stanley Michael Gartler (born June 9, 1923) is a cell and molecular biologist and human geneticist. He was the first scientist to offer conclusive evidence for the clonality of human cancers. He showed that
HeLa cells had contaminated many cell lines thought to be unique
.
What did Stanley Gartler discover about 18 of the most commonly used cell cultures when did he make this discovery?
The HeLa Bomb (1966)
He discovered this when he was running an experiment with the most commonly used cell cultures and found that they contained a genetic marker exclusive to black Americans. And a more amazing realization: HeLa could float through the air on dust particles.
What technical problem did Stanley Gartler expose with regards to cell cultures?
The HeLa Bomb (1966) The geneticist Stanley Gartler told his audience at the Conference on Cell Tissue and Organ Culture that they had a huge, huge problem:
whether they realized it or not, all their cell cultures were contaminated by HeLa
.
What did Stanley Gartler reveal at the second decennial review conference on cell tissue and organ culture?
What did Stanley Gartler reveal at the Second Decennial Review Conference on Cell Tissue and Organ Culture? Why was this devastating news for the scientists who heard this talk? Gartler revealed that
HeLa cells are contaminants
. Scientists tried to keep their cell cultures viral and bacterial free.
What unique abilities did HeLa have on cultures?
HeLa cell
could float through the air on dust particles
. They also could travel from one culture to the other in hands an pipettes or from lab to lab in researcher's coats or shoes, and ones they landed in an culture dish they fill all the space in it.
What was the HeLa bomb?
The “HeLa Bomb” refers to
the shocking discovery that the cell line of Henrietta Lacks had inadvertently contaminated unrelated cell lines
because researchers had been unaware of physical properties of Henrietta's cells that allowed for the easy, inadvertent transfer of those cells into other cell cultures.
What did Stanley Gartler discover about the relationship between HeLa and the other cell lines?
In his presentation, Gartler revealed
the HeLa cells' capacity to pass themselves off as other cells and contaminate the samples with which they came into contact
. He was able to identify the HeLa cells because they formed the only cell line included in Gartler's sample that was derived from a black person.
What happened when gartler announced HeLa contaminated?
Since some of these cell cultures had been taken from caucasian subjects, Gartler's conclusion was that all of the cell cultures had been contaminated—with HeLa. When Stanley Gartler revealed that six of his HeLa contamination samples
came directly from the ATCC
, the mood at the conference shifted dramatically.
What is the enzyme in HeLa cells that allow it an effective immortality?
The enzyme telomerase
copies telomeres over and over again, lengthening the telomeres. The result is unlimited cell division and immortality. The famous HeLa cells, isolated from the cervical cancer tissue of Henrietta Lacks in the 1950s, are still dividing.
How did Bobette respond to Deborah's pregnancy?
How did Bobbette respond to Deborah's pregnancy?
She cried
.
What are night doctors Where did the term originate and why what do the Lackses believe night doctors do is their belief based on real events?
“The term ‘night doctor' (derived from the fact that victims were sought only at night) applies
to both students of medicine
, who supposedly stole cadavers from which to learn about body processes, and professional thieves, who sold bodies- living and dead- to physicians for medical research” (Fry 171).
What was the HeLa bomb that was dropped at the cell Convention?
1966: At a conference in Virginia, Stanley Gartler “dropped” what is known as the “HeLa bomb”. He made the
discovery that most of the other existing cell lines had been contaminated by the HeLa cell line
(containing the G6PD-A genetic marker).
How did the Lacks family react when bobbette told what she had learned?
Bobbette was royally freaked out to learn
that Henrietta's cells were in this man's lab
. The family didn't know. Even worse, Bobbette learned from him that everyone and his uncle had been ordering vials of her cells for scientific experiments.
Who is Alexis Carrel and what did he claim to have accomplished?
This began in 1912, when a French surgeon named Alexis Carrel claimed to have
grown an “immortal chicken heart
.” A Nobel Prize-winner, Carrel became a celebrity, and the press trumpeted that he had found the key to immortality.
What disturbing discovery did scientists make about the way HeLa responded in orbit?
What disturbing discovery did scientists make about the way HeLa responded in orbit? The disturbing discovery the scientist found was that
the HeLa cells were growing even faster than they ever had before
.
