History of Medicine: The HeLa Cells

The main complaint of the family was that she did not ask for Henrietta's consent, and her and her family lacked respect. When talking about cell collection and patient consent, you have to ask yourself how your patient understands how your cell affects themselves and others. In the case of Henrietta Lacks, the fact that they sampled from her did not directly affect her. But her family ultimately suffered through unwelcome propaganda, after knowing where the cell came from, or when the doctor did not ask Henrietta for approval.

But what is HeLa cell? It is a cell line or cell taken from a person and used for scientific research. Cell lines are usually named after those from whom they originally originated, and HeLa is from the first two letters of the name Henrietta Lacks. Cell lines are used in various ways, such as studying the effects of disease, developing medicines and vaccines, playing an important role in today's medicine. However, HeLa cells were the first human somatic cell line (in vitro) that survived in vitro. Named for cancer patients, these cells were taken from tissue samples of Lacks and planted by researchers, Dr. George Gey in 1951. When those people die, they just continue to grow. After more than 50 years of development, there are billions of HeLa cells in laboratories around the world. It is the most commonly used cell line and is known to be very resilient.

1 - HeLa cells are cancerous. Looking at the chromosome (karyotype), the difference between normal cells and HeLa cells is most prominent. Like many tumors, HeLa cells have an erroneous genome containing more than one copy of chromosome. Normal cells contain 46 chromosomes and HeLa cells contain 76 to 80 (ref) total chromosomes. (22-25), per cell. This is due to human papillomavirus (HPV), the cause of almost all cervical cancer. HPV inserts its own DNA into the host cell and additional DNA inhibits it and prevents native p53 repair mutation and inhibits the tumor and causes genomic mismatch as unchecked cell division occurs Resulting in the production of p53-binding protein that results in accumulation.

HeLa / hi / / (Hela or hela too) is an immortal cell line for scientific research. It is the oldest and most commonly used human cell line. This series is derived from cervical carcinoma cells obtained by Henrietta Lacks, a patient dying on cancer on 4th October 1951, 8th February 1951. This cell line was found to be very durable and abundant. This proves its widespread use in scientific research. Cells from cancerous cervical tumor of Lacks were collected without consent from her. Cell biologist George Otto Gey discovered that they could survive, separate specific cells, regenerate it, and develop cell lines. (Previously, cells cultured from other human cells could only survive for a few days, scientists spent more time surviving the cells than actually doing research on the cells. Behavior is different.)
