Microbioreactor design for eukaryotic cell-based biomedical applications

Area of Science:

• Biotechnology and Biomedical Engineering
• Cell Biology and Tissue Engineering
• Microfluidics and Bioreactor Technology

Background:

• The field of eukaryotic cell-based biomedicine is shifting from static cultures to controlled microbioreactor environments.
• This transition is driven by the need for improved cell therapies, bioproduction, and tissue engineering applications.

Purpose of the Study:

• To review high-value applications of microbioreactors in cell-based biomedicine.
• To highlight technological advancements and their impact on cell manufacturing and tissue development.
• To discuss the role of automation and microfluidics in enhancing reproducibility and control.

Main Methods:

• Integration of microfluidics in Chimeric antigen receptor T-cell manufacturing for automated workflows.
• Perfusion-based microbioreactors with at-line monitoring and cell-retention for bioproduction.
• Microfluidic platforms modulating convective flow and mechanotransduction for tissue morphogenesis.

Main Results:

• Microfluidics optimizes cell count and phenotype distribution in T-cell manufacturing.
• Perfusion microbioreactors show a six-fold increase in productivity compared to T-flasks.
• Microbioreactors produced organoids 140% larger than static controls due to superior mass transfer and low shear stress.

Conclusions:

• Microbioreactors streamline therapeutic pipelines and support the replacement of animal testing.
• Advancements in microbioreactor technology accelerate personalized medicine and ethical drug screening.
• Challenges in scalability and material selection need to be addressed for wider adoption.
