They argued that publishing that genetic data could disclose important, personal health information that might enable life insurance or disability coverage companies to unfairly discriminate against the family. In 1955, researchers used HeLa cells to study the nutritional needs of cells in tissue culture media. Before starting the protocol: - Bring cell media, PBS, and trypsin to room temperature. Although they tendto grow in discrete patches, these cells also grow attached to the substrate. Cell culture is a technique in which cells isolated from a specific type of tissue are grown under controlled conditions in the lab. The HeLa cell line has prompted various bioethical debates, some which are still ongoing as of 2020.

The cancer cells, now called HeLa cells, grew rapidly in cell culture and became the first human cell line. However, some cells are immortal and do not die after a set number of divisions, as a result of alterations that can happen to certain cells, like cancer cells for example. That decision enabled scientists to continue utilizing the genomic data to further promote research involving the HeLa cell line. Homo sapiens partial mRNA for putative protein kinase ERK3. 271: 24105-24114, 1996. J. Virol.

With the homogeneity and immortality of cells in cell lines like HeLa, that helps ensure that when using laboratory-grown cells, different scientists yield the same results when replicating other scientists’ research using those cells. Mislabeled cell lines posed a threat to the integrity of scientific research experiments because if HeLa cells had contaminated what scientists reported as new cell lines, any research using those supposed cell lines would not be novel, as their research was simply on more HeLa cells. 178: 6281-6287, 1996. USA 93: 5894-5898, 1996. Skloot recounts in her book how Lacks’s daughter Deborah Lacks Pullum had heard stories about The Johns Hopkins Hospital enlisting black people for research and how Lacks’s family was not well educated about the disease that killed Henrietta Lacks. The HeLa cell line has enabled scientific advancements in many research areas, from the development of the polio vaccine to the understanding of how human papilloma virus can cause cervical cancer. Centers for Disease Control and Prevention. For example, though Gey, the original HeLa researcher, gave away HeLa cells to his colleagues and to anyone who requested them, the cell line and its resulting discoveries were extremely lucrative.
