HeLa y las CÉLULAS INMORTALES | 8 de febrero

The transcript discusses the origin and significance of HeLa cells, the first immortal human cell line derived from Henrietta Lacks, who suffered from cervical cancer. Before 1951, growing human cells was challenging as they couldn't survive long. However, HeLa cells, discovered in 1951, overcame these challenges due to their ability to divide indefinitely, a trait of cancer cells. These cells have been pivotal in medical research, contributing to the development of the polio vaccine and being the first human cells cloned. HeLa cells have been mass-produced and used in various research areas, including cancer, AIDS, and toxicology, leading to over 80,000 scientific articles and 11,000 patents.

What was the main challenge in growing human cells before the discovery of HeLa cells?
