The Role of Hela Cell in Medical Development Essay

He also gave brief description about National foundation for infantile paralysis which was established in 19th century by FDR and Basil O conor it helped in bringing awareness about polio in entire America .It also changed the way of sanctioning license to release the tested new drugs into the market, and also the way in which legal system dealt with manufacturers liability for using the unsafe and harmful products.

In 1951, the first immortal cell line was created by a doctor at Johns Hopkins Hospital using tissue samples taken from a young, black woman named Henrietta Lacks. Her cells would come to be known as HeLa cells, and for a very long time, the owner of these cells was a mystery; even her family did not know about them. For years to come, her cells would be used in many important medical and scientific advancements. Over that time, HeLa cells would prove to be instrumental in developing a polio vaccine, gene mapping, and in vitro fertilization. They would even be sent to space to see how cells would react in zero gravity.

In addition to health-related advances, such as the artificial heart valve, DNA structure decay, penicillin, and antibiotics. As well, we can not forget the start of the fight with cancer by the memorable world’s first cancer treatment with Cobalt-60 radiation. Although, new surgical procedures were introduced like the first successful kidney transplant and immunizations like typhoid, smallpox, tetanus, and polio vaccines. Polio epidemics had been occurring in the United States since 1916 according to the Centers for Disease Control and Prevention. The viral disease struck even important figures as President Franklin Roosevelt that forced him to use a wheelchair and wear steel braces on his legs privately. “In the 1940s and 1950s, widespread polio epidemics terrorized the nation. Finally, research scientist Jonas Salk developed an injectable vaccine to prevent polio. In 1955 the vaccine became available to the general public. American scientist Albert Sabin then developed an oral vaccine for polio. Safer and more convenient than Salk’s injection vaccine, the Sabin vaccine became the most common method for preventing the disease. The threat of polio nearly disappeared and many more diseases no longer affected the American people” (Appleby, Joyce 2004). Therefore, the treatments and cures of several epidemics and diseases were an important factor that caused the Baby Boom due to the decrease in the children’s mortality rates and their possibility to reach adult

HeLa simply stands for Henrietta Lacks, a young mother in the 1951 who went to the doctor complaining of vaginal bleeding and discovered she had cervical cancer. Henrietta’s cells were taken for a biopsy and were found to be like nothing ever seen before; her cells were immortal. Her cancer cells double every 20 to 24 hours and have lived on for the past 60 years. Since HeLa cells were created, our world of modern medicine has been completely changed. We now vaccines for once incurable diseases and have used the cells for cloning and other biomedical research. Although the cells have done a great deal of good,

The HeLa cells are the first immortal cell lines. Immortal cell lines are not like other cells. These cells don’t die of old age. Immortal cells are important because these cells grow indefinitely and they survive and grow by dividing. This allows scientists to research more productively. HeLa cells are used for many researches to cure diseases and develop new drugs. With HeLa cells scientists did many researches and it led to breakthroughs in the study of leukemia, influenza, hemophilia, Parkinson’s disease, cancer, AIDS, and more. It became one of the important tools in medicine. These improvements in diseases saved lives of many people. HeLa cells are coming from an African American female from Baltimore. HeLa cells are taken from Henrietta Lacks’ cervix

Henrietta Lacks was a young African American woman. Doctors experimented on her in order to form the HeLa cells, which was an immortal cell line, obtained from her body, and used in scientific research. She was born in Roanoke, Virginia, and known by the name of Loretta Pleasant. When her mother died, she changed her name to Henrietta Lacks, and was sent to live with her grandfather in an old slave quarters. She roomed with her cousin, Day Lacks, who later fathered her two children, Lawrence and Elsie.

HeLa cells are cells collected from Henrietta Lacks that have helped in many different medical advancements. HeLa cells helped to create in vitro fertilization, the polio vaccine, and some cancer treatments, to name a few. They were cervical cancer cells that served as an immortal cell line for scientific research. HeLa cells were the first line of human cells that survived in a test tube. They were taken and grown by Dr. George Gey in 1951.

Rebecca Skloot is a scientific journalist who first heard the name ‘Henrietta Lacks’ in a college classroom in the 1980s, when she was a teenager. Henrietta was a black American woman who died of cancer in 1951 at age 31. Before she died, a sample was taken from her tumor, without her knowledge or consent, and used for medical research. The cells in Henrietta’s tissue sample, known as HeLa (pronounced hee-lah) were the first human cells to survive in culture – they not only survived, but thrived and multiplied. Consequently, HeLa cells have since been used in scientific research all over the world, and have played a fundamental role in numerous medical advances and developments.

The woman commonly known as Henrietta Lacks is a woman who's cells were unrightfully used by scientists for their own benefit. Although her cells have caused great achievements and scientific discoveries in science she was never credited for her unauthorized donation of cells. Henrietta Lacks might not even be her real name, and because of this the cells have been referred to as the HeLa cells. Consent has always been a major issue in scientific discovery and scientific testing, but no one specifically gave the scientists promotion to remove cells from Henrietta Lacks dead body.

While Henrietta was pregnant with her fifth child, she started experiencing abnormal bleeding. Eventually, her doctor discovered a lump on her cervix which was diagnosed as cervical cancer. Henrietta Lacks died of cervical cancer on October 4, 1951 at age 31. After testing the cervical cancer cells, researchers noticed that Henrietta’s cells would not divide and die. The cells kept replicating. This led researchers to to create the HeLa line based on

The scientific development of the HeLa cells has made a huge impact in the medical field. HeLa cells are a cell line created from the doctors of Johns Hopkins Hospital. These cells are from a woman named Henrietta Lacks and are considered to be “immortal”. They are considered to be unique because they are not like any other normal human cell. This cell line is considered to be a triumph to many scientists and researchers, but it also had some negative impacts. Many controversies arose from the development of these cells such as how doctors at Johns Hopkins did not get consent from its patients, how the Lacks family received nothing even with the success of HeLa cells, and the racial segregation that has become one of the reasons for the creation

He knew that Polio caused paralysis, and invaded the nervous system. As a result, he wanted to end the greatest epidemic in America at that time. As he began researching, the president of the March of Dimes Foundation, Basal O’Connor, wanted to help Salk create the Polio vaccination. His goal was to fund Salk to find a cure against Paralytic Poliomyelitis, or Polio. Jonas devoted the next 8 years of his life working to develop the vaccine. He finally was able to create the vaccine, using formaldehyde, or a chemical compound. Salk used the killed Polio virus to immunize without being infected, or becoming infected after the injection. Soon after the vaccine was created, they began to test it on monkeys; and then they tested it on children who already had Polio at the Watson Institute. After that trial was done, the testing spread to volunteers who wanted the vaccine; this included Jonas, his wife, and his family. By 1954, national testing began on children between the ages of 6-9. On April 12, 1955, they were able to conclude that the vaccine was safe and effective. Salk became known as a miracle worker, although he remained selfless. Jonas wanted no major payment, or recognition for the creation of the vaccine. In fact, he credited that the vaccine creation was accomplished due to the help of John Enders, a Harvard researcher. Enders was the man

Polio had already killed 3,000 people at its peak rate in 1952; sadly, it had already paralyzed thousands of more people (Soylent 1)On April 12, 1955 the polio vaccine developed by Salk was allowed to be used by the public after it had been tested with 1.8 million children (Biography 1). The vaccine had drastically reduced the number of polio cases in children by 90%; 57,000 cases were recorded in 1952 and less than one thousand cases a decade later (Soylent 1). In addition, Jonas Salk later established his own institution for research named Salk Center for Biological Studies in 1963. The institution “remains one of the world's most prestigious facilities for research into AIDS, Alzheimer's disease, Parkinson's

The discovery of the polio vaccine was an important medical and scientific breakthrough because it saved many lives since the 1950s. In the summer of 1916 the great polio epidemic struck the United states. By the 1950s hundreds of thousands of people had been struck by the poliomyelitis. The highest number of cases occurred in 1953 with over 50,000 people infected with the virus.

“A 1916 Polio epidemic in the United States killed 6,000 people and paralyzed 27,000 more” (“Polio Vaccine”). This lead to the creation of the polio vaccine that has helped to prevent polio for a very long time. The IPV and OPV vaccines played a huge role in all of this. Jonas Salk, who created the IPV vaccine and Albert Sabin, who created the OPV vaccine saved millions of people all around the world from polio (Petersen, Jennifer B). The IPV and OPV polio vaccine helped eliminate polio from the United States and helped prevent polio in other parts of the world (“Polio Vaccine”).
