Answer:
Pros of HeLa cells:
- HeLa cells are immortal ,easy to maintain and can be kept alive.
- HeLa cells easily contaminate cell lines and thus can be incorporated easily into target tissues.
Cons of HeLa cell:
- The HeLa cells can easily contaminate cell lines and a lack of regular monitoring leads to unwanted contamination of cell lines resulting in wastage.
Explanation:
HeLa cells are immortal cells that are used in scientific and medical research. These were obtained from Henrietta Lacks , a cervical cancer patient. These cells are well known for their immortality, rapid growth and high contamination rate. These were unique cancerous cells that kept on dividing and remained alive easily.
