In recent years, viral vector technology has made remarkable progress, extending beyond use in basic research to clinical applications in gene therapy. However, many vectors lack reproducibility, and it is not uncommon for results to vary depending on experimental conditions. It is challenging for individual researchers to verify the reproducibility of viral vectors of mixed quality and to independently develop original viral vectors for use in their research. This project aims to establish a solid foundation for the rapidly evolving field of viral vector technology, with the objective of creating a world-class center for viral vector development.
