Biologics manufacturing relies heavily on optimizing various stages, yet the seed train step - often overlooked - plays a critical role in determining overall efficiency. The seed train involves expanding cells from a small working cell bank to scales suitable for production bioreactors.

Francois Carruzzo, Co-founder and CTO of Bioscibex, is rethinking how this process can be simplified, streamlined, and made more reliable, using a fully automated, closed system. However, the complexity of scaling introduces several risks, including handling errors, contamination, and delays that could derail production timelines.

Today, seed train processes involve multiple vessels, open handling, and labor-intensive steps, all of which complicate operations. François identified two prominent challenges:

• Contamination Risks: Multiple open steps, such as using spin tubes, shake flasks, and wave systems, result in a heightened potential for contamination.
• Operational Complexity: With multiple campaigns and products running simultaneously, accommodating different media types and containers can become overwhelming.

Bioscibex is on the verge of revolutionizing seed train operations with its innovative single-use bioreactor system. François shared how this system addresses traditional shortcomings:

• Wide Turndown Ratio: Capable of scaling from 30 mL all the way to 30 L within the same vessel, Bioscibex's rocking motion reactor eliminates multiple intermediary steps.
• Closed Workflow: By maintaining a fully enclosed environment, the system dramatically lowers contamination risks, making bioprocessing more reliable.
• Continuous Cell Expansion: Unlike traditional methods that involve batch dilutions, Bioscibex supports continuous cell expansion, ensuring optimal growth conditions with reduced downtime.

Innovation in seed train processes extends far beyond mere operational efficiency. It lays the groundwork for scalable, consistent biologics production, ensuring therapies can reliably reach clinics faster.

By simplifying the mundane yet critical seed train step, his innovation offers a glimpse into the future of stress-free, scalable cell expansion - a vision we’re excited to see unfold.
