Vero cell

Vero cells are a type of cell line that is widely used in virology and other biological research areas. Originating from the kidney epithelial cells extracted from an African green monkey (Cercopithecus aethiops), Vero cells are known for their ability to grow in culture and are used for the production of viral vaccines and for research on viral pathogens.

History

Vero cells were first isolated in 1962 by Y. Yasumura and Y. Kawakita at the Chiba University in Japan. The name "Vero" is derived from "verda reno," which means "green kidney" in Esperanto, reflecting the cells' origin. Since their discovery, Vero cells have become one of the most important cell lines in virology due to their high efficiency in propagating viruses.

Characteristics

Vero cells are characterized by their fibroblast-like shape and their ability to reach high cell densities in culture. Unlike many other cell lines, Vero cells do not produce interferon, a type of protein that is part of the immune response against viral infections. This lack of interferon production allows viruses to replicate more efficiently, making Vero cells an ideal tool for virology research.

Applications

Vero cells are used in a variety of research and industrial applications. One of the most significant uses of Vero cells is in the production of viral vaccines. They are used to propagate viruses for vaccines against diseases such as polio, rabies, and smallpox. In addition to vaccine production, Vero cells are also used in basic research to study viral life cycles, pathogenesis, and host-virus interactions.

Safety and Regulation

The use of Vero cells in vaccine production is subject to strict regulatory oversight to ensure the safety and efficacy of vaccines. The World Health Organization (WHO) and other regulatory bodies have established guidelines for the use of cell lines in vaccine manufacture, including the characterization and testing of cell lines for contaminants.

Controversies

The use of Vero cells, like other animal-derived cell lines, has raised ethical concerns regarding animal welfare and the use of animals in scientific research. Additionally, there have been concerns about the potential for contamination with animal viruses, which could pose risks to human health. However, rigorous testing and regulatory standards are in place to minimize these risks.

Future Directions

Research on Vero cells continues to evolve, with ongoing studies aimed at improving the safety and efficiency of these cells for vaccine production and other applications. Advances in genetic engineering and cell culture technology may lead to the development of new Vero cell lines with enhanced properties for research and industrial use.
