WHY
ARE HENRRIETTA LACK’s CELLS SO IMPORTANT?
Henrietta
Lacks was an AFRICAN-AMERICAN woman who died by a tumor in the
neck of the uterus.
More than 60 years ago, in one of
the few hospitals in Maryland (USA) that catered to blacks, a doctor isolated
the first immortal human cells (the cells of Henrietta).
The history of HELA cells is back
at the beginning of the 1950s, when the American doctor George Otto Grey
managed to cultivate a tumor removed from the young Henrietta Lacks shortly
before his death.
Henrietta Lacks died of cancer
shortly after surgery, without knowing what became of the removed tumor and
consent to its use. The conclusion of this story is that human cells can be
immortal, while the body has a limited lifetime.
After the first achievement with
HeLa cells, other cells of different origins have been cultivated. Over time,
the HeLa cells have been used to explain phenomena such as the replication of
the chromosomes, the viral infections and the effects of ultraviolet light.
Today these cells continue to be a source of information and their legacy is
perpetuated in laboratories around the world.
Although she died more than half
a century ago, Henrietta Lacks is the older person in the world in his
thirties.
