Session Description
Human embryonic kidney 293 (HEK293) cells remain the leading host for production of viral vectors used in gene therapy, including AAV and lentiviral systems. This workshop presents the development of an integrated HEK293 media and expression platform specifically optimized for high-yield viral vector manufacturing.
The program combined clonal suspension HEK293 cell line engineering with chemically defined, animal component–free media development to enhance viable cell density, transfection efficiency, and vector productivity. Design-of-experiment (DoE) strategies were applied to optimize amino acid balance, energy substrates, trace elements, and lipid supplementation to support high-density transient transfection processes. Particular emphasis was placed on improving plasmid uptake, reducing metabolic stress during vector production, and maintaining critical quality attributes.
The resulting platform demonstrates improved viral titer and potential robust scalability from shaker flasks. Attendees will gain practical insights into aligning host cell engineering and media design to enable efficient, scalable gene therapy manufacturing workflows.
Session Objectives:
- Integrated platform development drives yield gains
- Process robustness reduces risk
- Chemically defined systems support regulatory readiness
- Scalability must be engineered early
- Platform flexibility shortens timelines
