Integrated T-Cell Enrichment, Static Transduction, and Expansion in Gas-Permeable Bioreactors for Adoptive Cell Therapy

This study details an integrated, closed CAR T-cell manufacturing workflow. The process utilizes a G-Rex 100M-CS bioreactor for direct in-vessel CD4+/CD8+ magnetic enrichment using a prototype SepaRex base, static retroviral transduction, and T-cell expansion, eliminating separate selection or spinoculation devices.
