The Vero cell line is now one of the most commonly used cell line for biopharmaceuticals production such as cell culture-based viral vaccines. An example is the successful production of both live (rotavirus, smallpox) and inactivated (poliovirus) viral vaccines. Reasons for the extensive use of the Vero cell line are the consistent high viral yields and relatively easy adaptation for growth in bioreactors on microcarriers, thus allowing greater vaccine purity and as well as quantity.
Currently available media to cultivate Vero cells contain undefined plant hydrolysates or animal derived raw materials such as yeastolates. These undefined materials lead to variability in media performance, a result of lot-to-lot variations, increased potential for contamination, as well as inconsistency when scaling-up for commercial processes. Sartorius has introduced 4Cell® NutriVero™ Flex 10 Medium, a chemically defined (CD), serum-free, animal origin–free and hydrolysate-free medium optimized for both 2D monolayer and 3D microcarrier suspension culturing of Vero cells. It reduces process variability and enhancing process safety, providing greater predictability during scale-up and improved virus productivity achieving comparable performance to hydrolysate-containing, serum-free media.
