Main Results:

Packaging cell growth kinetics were similar in microfluidic and static conditions.
Comparable virus production levels were observed at 37°C between microfluidic and static cultures.
Immediate cold storage downstream of microfluidic bioreactors increased active virus production by 1.4- to 3.7-fold over 5 days.

Conclusions:

Microfluidic bioreactors offer a viable platform for continuous retrovirus production.
Integrating downstream cold storage in microfluidic systems significantly enhances retrovirus yield and stability.
These microfluidic devices are valuable for optimizing viral vector production for gene therapy.
