HeLa Cells How HeLa Cells got it's Name HeLa cells being shipped In less then two years of Henrietta's death, samples of her cells were packaged in ice and cardboard and sent around the world for research. HeLa cells have been shipped around the globe and deployed in all manner of research. Frozen HeLa cells The cell lines they need are “immortal”—they can grow indefinitely, be frozen for decades, divided into different batches and shared among scientists. Most famously, the cells were used to test the Salk polio vaccine. They helped make Deborah Lacks’s antidepressants and blood-pressure pills, they led to injection techniques used for in vitro fertilization and gene therapy. HeLa even rode along with astronauts to outer space. BY: Keasha and Suzi
Period 7
January 28, 2013 It all started after Henrietta Lacks had her fifth child. She had started bleeding abnormally and profusely. She went to the hospital and Dr. John Hopkins found a lump in her cervix. He cut out a small piece of the tumor and sent it to the pathology lab.Soon after, Jones discovered she had cervical cancer. Lacks was treated with radium tube inserts, which were sewn in place. After several days in place, the tubes were removed and she was released from Johns Hopkins with instructions to return for X-ray treatments as a follow-up. During her radiation treatments for the tumor, two samples of Henrietta's cervix were removed— a healthy part and a cancerous part— without her permission. The cells from her cervix were given to Dr. George Otto Gey. Lacks returned for the X-ray treatments. However, her condition worsened and the Hopkins doctors treated her with antibiotics, thinking that her problem might be complicated by an underlying venereal disease. In significant pain and without improvement, Lacks returned to Hopkins on August 8th for a treatment session but asked to be admitted. She remained at the hospital until her death. Though she received treatment and blood transfusions, she died of uremic poisoning on October 4, 1951 at the age of thirty-one. A subsequent partial autopsy showed that the cancer had metastasized throughout her body. In honor of her they name HeLa cells after Henrietta. It has her first two letters in her first and last name. THE END
