The Science of HeLa Cells
Skloot’s book details the scientific basis for HeLa cells’ unique immortality, exploring the cellular mechanisms behind their continuous division and growth.
What Makes HeLa Cells Immortal?
The remarkable characteristic of HeLa cells, as explored by Skloot, stems from their ability to bypass normal cellular senescence – the process of aging and eventual cell death. Unlike most human cells, HeLa cells don’t stop dividing after a certain number of divisions. This is due to a complex interplay of factors, including the cells’ unusually active telomerase enzyme.
Telomerase maintains the length of telomeres, protective caps on the ends of chromosomes, preventing them from shortening with each division. This prevents the triggering of cellular aging processes. The book highlights how this immortality has made HeLa cells invaluable for scientific research, but also raises significant ethical questions.
Telomeres and Cellular Aging
Skloot’s research details how telomeres, the protective caps on the ends of our chromosomes, shorten with each cell division, ultimately triggering cellular aging and death. This natural process limits the number of times a typical human cell can divide. However, HeLa cells exhibit a unique characteristic: they maintain their telomere length.
This preservation is achieved through the constant activity of telomerase, an enzyme that rebuilds telomeres. Consequently, HeLa cells circumvent the normal aging process, achieving a form of biological immortality. This phenomenon is central to understanding their widespread use in scientific study.
The Role of HPV in HeLa Cell Immortality
Skloot’s investigation reveals Henrietta Lacks was diagnosed with cervical cancer caused by Human Papillomavirus (HPV). The specific strain of HPV she carried contained a gene that inactivates tumor suppressor proteins, crucial for regulating cell growth. This inactivation, combined with the telomerase activity, contributed significantly to the HeLa cells’ immortal nature.
The HPV infection essentially removed the brakes on cell division, allowing the cells to proliferate indefinitely. This discovery highlighted the virus’s role in cancer development and the unique characteristics of the HeLa cell line, furthering its value in research.
