Anti-proliferative effects of T cells expressing a ligand-based chimeric antigen receptor against CD116 on CD34+ cells of juvenile myelomonocytic leukemia

The authors developed GM-CSF Receptor (CD116) CAR T cells using the piggyBac transposon system. The transgenic CAR T cells were expanded in G-Rex 10 devices to generate effector cells for testing against JMML cells.

Safety of Intra-Arterial Injection With Tumor-Activated T Cells to the Rabbit Brain Evaluated by MRI and SPECT/CT

This study evaluated the safety of intra-arterial TIL delivery in rabbits. The human TILs used for infusion were expanded from glioblastoma tumors using G-Rex to obtain sufficient cell numbers for the experiment.

Plasticity and Aggregation of Juvenile Porcine Islets in Modified Culture: Preliminary Observations

The study reports that culturing juvenile porcine islets in Wilson Wolf gas-permeable (G-Rex) allows them to aggregate into functional 'pancreatites'. These flasks were also used for shipping the islets, maintaining viability and function.

Expansion of tumor-infiltrating lymphocytes (TIL) from human pancreatic tumors

The study demonstrates successful expansion of tumor-reactive TILs from pancreatic cancer. The Rapid Expansion Protocol (REP) was performed using GREX10 to stimulate and expand the TILs with anti-CD3 and feeder cells.

The beneficial effects of a gas-permeable for expansion of Tumor-Infiltrating lymphocytes as reflected in their mitochondrial function and respiration capacity

This paper investigates the use of G-Rex for TIL rapid expansion. Results show G-Rex rescues poor TIL growth, preserves clonal diversity, and yields cells with a more oxidative metabolic phenotype (higher mitochondrial capacity) compared to traditional flasks/bags.

Efficient mRNA-Based Genetic Engineering of Human NK Cells with High-Affinity CD16 and CCR7 Augments Rituximab-Induced ADCC against Lymphoma and Targets NK Cell Migration toward the Lymph Node-Associated Chemokine CCL19

This study shows efficient mRNA electroporation of NK cells. Clinical-grade NK cells were expanded ex vivo using G-Rex prior to electroporation, allowing for the generation of large numbers of highly cytotoxic cells.

Early transduction produces highly functional chimeric antigen receptor-modified virus-specific T-cells with central memory markers: a Production Assistant for Cell Therapy (PACT) translational application

The authors developed a method for early transduction of trivirus-specific T cells. The clinical SOP utilized G-Rex100 for the second stimulation phase to rapidly expand transduced VSTs to clinically relevant numbers.

Ex vivo expansion of human T cells for adoptive immunotherapy using the novel Xeno-free CTS Immune Cell Serum Replacement

The study validates a xeno-free serum replacement for T cell expansion. It demonstrates that combining OpTmizer medium with CTS Immune Cell SR in G-Rex culture vessels promotes optimal expansion of antigen-specific T cells compared to standard flasks.

Effector CD8+ T cell engraftment and anti-tumor immunity in lymphodepleted hosts is IL-7Rα dependent

The study found that IL-12 conditioning increases IL-7Rα, crucial for T cell persistence. For clinical translation, TCR-transduced human T cells were expanded using a rapid expansion protocol in G-Rex 100 to generate large numbers of cells for analysis.
