VERO Cells vs. Other Cell Lines in Biopharma

When comparing VERO cells with other cell lines like SH-SY5Y, HeLa, and HEK293, it's clear that VERO cells hold notable advantages, particularly in viral productivity. VERO cells have been shown to outperform other lines in producing viral vectors, largely due to their non-cancerous origin and regulatory acceptance for pharmaceutical applications. Grein et al. (2017) emphasize these benefits, making VERO cells a preferred choice for researchers.

For instance, while SH-SY5Y cells are primarily used in neuroscience research, their utility in viral vector production is limited compared to VERO cells. Similarly, although HeLa cells are well-known for cancer research, ethical concerns and scalability issues may favor VERO cells in pharmaceutical-grade applications.
