5 Must Know Facts For Your Next Test

  1. Vero cells are highly susceptible to a wide range of viruses, making them a valuable tool for viral isolation and propagation.
  2. Vero cells are commonly used to isolate and culture viruses such as poliovirus, influenza virus, and SARS-CoV-2, the virus that causes COVID-19.
  3. The ability of Vero cells to support the growth of many different viruses is due to their lack of functional type I interferon genes, which are important for the innate immune response against viral infections.
  4. Vero cells are known for their ability to produce high viral titers, which is essential for the production of viral vaccines and the study of viral pathogenesis.
  5. The use of Vero cells in virology research has contributed to the development of various diagnostic tests, antiviral therapies, and vaccine candidates.
