The
amazing HeLa cells of Henrietta Lacks
In
early 1951, Ms. Lacks, a 31-year old mother of five children, was found to have
a malignant tumor of the cervix. During her examination at Johns Hopkins
Hospital in Baltimore, MD, a sample of the tumor was removed and provided to
Dr. George Gey. He was head of tissue culture research at Hopkins who for years
had been attempting to produce a line of immortal human cells. When Ms.
Lacks died in October 1951, Dr. Gey announced on national television that he
had produced from Ms. Lacks’ tumor a line of cells that propagated as no other
cells ever had before. He called them ‘HeLa’ cells in her honor, and showed a
vial of the cells to the television audience.
HeLa
cells have since been used in many laboratories all over the world to make
countless research discoveries. For example, shortly after Dr. Gey
announced the HeLa cell line, it was used to propagate poliovirus, an event
that played an important role in the development of poliovirus vaccines. But
Ms. Lacks’ family never learned about the important cells that were derived
from her until 24 years after her death. The history of this event, described in the Johns Hopkins
Magazine, is a commentary on the lack of informed consent common in
medical research at the time.
