The Vero cell line is the most used continuous cell line for viral vaccine manufacturing with more than 40 years of accumulated experience in the vaccine industry. Additionally, the Vero cell line has shown high affinity for infection by MERS-CoV, SARS-CoV and recently SARS-CoV-2, emerging as an important discovery and screening tool to support the global research and development efforts in this COVID-19 pandemic.
Furthermore, Vero cells anchorage-dependent use renders scaling-up challenging and operations very labor intensive which affects cost effectiveness. Thus, efforts to adapt Vero cells to suspension cultures have been invested but hurdles such as the long doubling time and low cell viability remain to be addressed.
However, the lack of a reference genome for the Vero cell line has limited our understanding of host-virus interactions underlying such affinity of the Vero cell towards key emerging pathogens, and more importantly our ability to re-design high-yield vaccine production processes using Vero genome editing. In this study, we present an annotated highly contiguous 2.9 Gb assembly of the Vero cell genome.
