Optimization and Scale-up of Treg Expansion from CD4+ Cells in G-Rex6M plates

This poster details the optimization of Treg expansion using Cloudz™ Treg CD3/CD28 microspheres. The method achieved high purity and cell numbers. Scalability was demonstrated using G-Rex6M plates, which utilize a gas-permeable membrane to support efficient cell growth in serum-free media.

Inhibition of MICA and MICB Shedding Elicits NK cell–mediated Immunity against Tumors Resistant to Cytotoxic T cells

The study demonstrates that blocking MICA/B shedding enables NK cells to target tumors with MHC-I or IFN-gamma pathway mutations. Human NK cells were expanded in vitro using G-Rex 6-well plates. This therapeutic strategy effectively reduced metastases in humanized mouse models.

Generation of Antitumor T Cells For Adoptive Cell Therapy With Artificial Antigen Presenting Cells

This study develops renewable artificial antigen presenting cells (aAPCs) for T cell expansion and transduction. Using G-Rex , aAPCs supported efficient production of CAR T cells and TILs with less exhaustion and higher potency than bead-based methods, offering a cost-effective manufacturing alternative.

Detection of response to tumor microenvironment–targeted cellular immunotherapy using nano-radiomics

This study explores nano-radiomics to assess response to MDSC-directed NK cell therapy in solid tumors. Human NK cells were activated and expanded in G-Rex devices for in vivo testing. Radiomic analysis of CT images successfully identified treatment responses that conventional tumor metrics failed to detect.

Production of Lentiviral Vectors Using Suspension Cells Grown in Serum-free Media

The authors developed a scalable, serum-free process for lentiviral vector production using suspension-adapted SJ293TS cells. The vectors efficiently transduced human T cells and CD34+ cells. G-Rex plates were employed to expand the transduced T cells for assessing chimeric antigen receptor expression and titer.

Rapidly expanded partially HLA DRB1–matched fungus-specific T cells mediate in vitro and in vivo antifungal activity

The authors describe a GMP-compliant method to rapidly expand fungus-specific T cells using CD137 selection and short-term culture. G-Rex cell culture plates were used for the in vitro expansion of the enriched CD137+ population. The resulting T cells demonstrated potent antifungal activity against Aspergillus.

Closing the system: production of viral antigen-presenting dendritic cells eliciting specific CD8+ T cell activation in fluorinated ethylene propylene cell culture bags

This study compares monocyte-derived dendritic cell (Mo-DC) production in fluorinated ethylene propylene bags versus polystyrene plates. Mo-DCs generated in bags showed comparable phenotype and ability to activate T cells. G-Rex were utilized for the T cell co-culture steps to assess activation potency.

Potential clinical application of tumor-infiltrating lymphocyte therapy for ovarian epithelial cancer prior or post-resistance to chemotherapy

Evaluated TIL ACT for ovarian cancer. TILs were expanded using a 'TIL 3.0' method combining IL-2 with agonistic 4-1BB and anti-CD3 antibodies in G-Rex 10. This method significantly increased CD8+ TIL yield and success rates compared to IL-2 alone, producing tumor-reactive T cells in 2-3 weeks.
