Polyethylene terephthalate (PET) microfibrous matrices offer a cost-effective, high-performance alternative for cell culture in bioreactors. These carriers support robust cell growth and monoclonal antibody production, outperforming commercial options.

Area of Science:

  • Biotechnology
  • Cell Culture Engineering
  • Bioprocess Development

Background:

  • Microfibrous matrices made from polyethylene terephthalate (PET) possess advantageous properties for cell culture.
  • These matrices offer high porosity, large surface area, and 3D space, ideal for dense cell growth in agitated bioreactors.

Purpose of the Study:

  • To evaluate the efficacy of PET microfibrous carriers compared to commercial microcarriers for Chinese hamster ovary (CHO) cell culture.
  • To assess cell attachment kinetics, growth, and monoclonal antibody (mAb) production using these carriers.

Main Methods:

  • Culturing CHO cells on PET microfibrous carriers and commercial microcarriers (solid and macroporous).
  • Analyzing cell attachment, growth rates, and mAb productivity.
  • Investigating the impact of agitation rates on cell viability and carrier performance.

Main Results:

  • PET microfibrous carriers demonstrated comparable or superior performance to commercial microcarriers in cell attachment, growth, and mAb production.
  • These carriers exhibited a broader operational range for agitation rates, enhancing cell protection against shear stress and collisions.
  • The cost-effectiveness of PET microfibrous carriers was significantly higher than commercial alternatives.

Conclusions:

  • PET nonwoven microfibrous matrices are a viable and economical alternative for microcarrier-based cell culture in agitated bioreactors.
  • They provide excellent support for high-density cell growth and productivity, with improved operational flexibility and cell protection.
