Cell Therapy Manufacturing Platform
Cell Expansion & Formulation Instrument
Cell therapies, particularly CAR-T, represent a breakthrough in treating cancers and infectious diseases, but today’s manufacturing processes are labor-intensive, costly, and difficult to scale, limiting patient access.
Scaling cell therapies requires precise control over expansion and formulation processes, often involving complex bioreactor systems and environmental regulation.
We developed a clinical cell expansion and formulation instrument designed to automate and scale downstream processing within a closed, GMP-compatible platform. The system supports both suspension and adherent cell processes while maintaining tight control over environmental and process parameters.
The instrument enables:
- Cell activation, expansion, and formulation
- Integration with bioreactor systems for scalable cell growth
- Advanced environmental monitoring and control
- Automated fluid handling and sampling
Key features include:
- Rocking motion platform for bioreactor compatibility
- Multi-channel fluidic management system
- Closed, single-use cartridge system
- Integrated touchscreen UI for process control
- Interconnectivity with upstream isolation system
Contributions
- User research and system requirements development
- Industrial design and workflow-driven architecture
- Mechanical design of fluidics, motion, and enclosure systems
- Electronics and control system integration
- Embedded firmware and user interface development
- Prototype development and system-level testing
- Regulatory strategy and design documentation support
Impact
A compact, scalable system engineered for GMP-compliant production, improved workflow efficiency, and reliable, repeatable process control without the need for traditional cleanroom infrastructure.
