CMV and EBV targets recognized by tumor-infiltrating B lymphocytes in pancreatic cancer and brain tumors
The study explores antibody responses from tumor-infiltrating B cells against viral antigens in cancer patients. G-Rex were used to expand tumor-infiltrating lymphocytes (TILs) from tumor tissue, facilitating the analysis of immune reactivity in the tumor microenvironment.

Generation of Tumor-Specific (tg-TCR) T Cells Using CRISPR-Mediated In-Locus Insertion Combined with Endogenous TCR Knockout
This study demonstrates a method for generating tumor-specific TCR-T cells using CRISPR/Cas9 for endogenous TCR knockout and AAV for TCR insertion. G-Rex 24-well plates were utilized for T cell expansion, supporting cell viability and growth during the editing process.
Publications
A Phase I Clinical Trial with Ex Vivo Expanded Recipient Regulatory T cells in Living Donor Kidney Transplants
This Phase I trial assessed the safety of infusing autologous expanded Tregs into kidney transplant recipients to induce tolerance. G-Rex were used to expand Tregs, achieving robust cell numbers and meeting all clinical release criteria without adverse events.

In Vitro Expansion of Anti-viral T Cells from Cord Blood by Accelerated Co-cultured Dendritic Cells
A method to generate virus-reactive T cells from cord blood using accelerated co-cultured dendritic cells (acDC). The use of G-Rex 10 significantly increased the yield of antigen-reactive CD8+ T cells compared to standard plates, enabling therapeutic dosing.
Publications
Tumor-infiltrating lymphocytes: Streamlining a complex manufacturing process
Reviews improvements to TIL manufacturing. Implementing G-Rex 100MCS devices for the Rapid Expansion Protocol (REP) reduced technical interventions, media usage, and contamination risk while maintaining comparable tumor specificity to flask/bag methods.
Publications
Enhanced clinical-scale manufacturing of TCR transduced T-cells using closed culture system modules
Evaluated a closed-system manufacturing process for TCR-transduced T-cells. The rapid expansion phase utilized closed G-Rex 500CS devices, yielding ~20 x 10^9 highly functional T-cells from a single vessel, improving safety and consistency.
Publications
Long Terminal Repeat CRISPR-CAR-Coupled “Universal” T Cells Mediate Potent Anti-leukemic Effects
Developed "universal" CAR T cells using a lentiviral vector coupling CAR expression with CRISPR/Cas9 gene editing. G-Rex were used for conventional control cultures to compare against the automated CliniMACS Prodigy system.
Publications
Large-scale in vitro production of red blood cells from human peripheral blood mononuclear cells
A scalable protocol for producing red blood cells from adult PBMCs was developed. The G-Rex allowed for massive expansion (3x10^6 fold) of erythroblasts and supported efficient differentiation and enucleation, comparable to standard culture dishes.
Publications
Bags versus: a comparison of cell culture systems for the production of dendritic cell–based immunotherapies
Review comparing cell culture systems (bags vs flasks) for dendritic cell production. Discusses gas permeability and materials. References Wilson Wolf patents related to gas-permeable devices as examples of improved culture methods utilizing silicone rubber membranes.
Publications
Prospective analysis of adoptive TIL therapy in patients with metastatic melanoma: response, impact of anti-CTLA4, and biomarkers to predict clinical outcome
Prospective analysis of TIL therapy in metastatic melanoma. The Rapid Expansion Protocol (REP) was performed using G-Rex 100M, contributing to the generation of infusion products. High TIL numbers were associated with response.
