Clinical scale rapid expansion of lymphocytes for adoptive cell transfer therapy in the WAVE®
Compares the WAVE to static gas-permeable bags for TIL and PBL expansion. While total cell numbers were comparable, the WAVE produced a higher percentage of CD4+ cells and a less activated phenotype. The study references G-Rex (Vera 2010) as an alternative static option

Optimization Manufacture of Virus- and Tumor-Specific T Cells
Reviews optimization of antigen-specific T cell manufacturing. Highlights the G-Rex device as a revolutionary tool that increases cell yields by 3-20 fold while reducing manipulation. G-Rex allows unrestricted media depth due to gas exchange from the bottom, linearly scalable from research to GMP production

PiggyBac-mediated Cancer Immunotherapy Using EBV-specific Cytotoxic T-cells Expressing HER2-specific Chimeric Antigen Receptor
Describes using the PiggyBac transposon system to modify EBV-CTLs to express HER2-CARs. The G-Rex device (G-Rex10 and G-Rex100) was used to expand the gene-modified CTLs, supporting long-term survival and stable transgene expression. G-Rex allowed efficient expansion of clinical-grade cells with minimal manipulation
Publications
Manufacture of GMP-grade Cytotoxic T Lymphocytes specific for LMP1 and LMP2 for Patients with EBV-associated Lymphoma
Outlines GMP manufacturing of LMP1/LMP2-specific CTLs for EBV-associated lymphoma. Describes using G-Rex devices for the second stimulation and expansion phases to support high-density cell growth. G-Rex simplifies the process and reduces labor compared to traditional 24-well plates while maintaining cell quality
Publications
Accelerated Production of Antigen-specific T Cells for Preclinical and Clinical Applications Using Gas-permeable Rapid Expansion Cultureware (G-Rex)
Evaluates G-Rex for expanding antigen-specific CTLs. G-Rex supports 3-20 fold higher cell output than 24-well plates by improving gas exchange and allowing deeper media. The device simplifies manufacturing by reducing interventions and supports high-density culture of CTLs and CAR-T cells without compromising function

Improved Islet Culture on Top of Gas-Permeable Membranes
Investigates culturing pancreatic islets on gas-permeable silicone rubber membranes. This method allows for higher surface densities (up to 4000 IE/cm²) and media depths compared to standard without hypoxic damage. G-Rex technology principles are tested here for islet survival and function

Development of large-scale expansion protocol for NKG2C-positive NK cells for treatment of glioblastoma
This study presents a protocol for large-scale expansion of NKG2C+ NK cells using PC-3 feeder cells. G-Rex 6M well plates were employed to achieve high expansion factors (median 358.5-fold) of functional NK cells for glioblastoma immunotherapy.
