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.

Cells on Demand™ Fresh Human Pancreatic Islets Technical Information & Instructions
This document provides instructions for Lonza's Fresh Human Pancreatic Islets. It highlights that the islets are shipped in Wilson Wolf G-Rex® gas permeable cell culture devices (G-Rex10 or G-Rex100) to maintain viability during transport and culture.

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.

Defining novel parameters for the optimal priming and expansion of minor histocompatibility antigen-specific T cells in culture
This paper establishes a clinical-compliant protocol to generate MiHA-specific T-cell lines. The priming phase utilized G-Rex10 to maximize cell expansion and DC-T cell interactions starting from limited PBMCs, followed by a rapid expansion protocol.

Coordinate regulation of residual bone marrow function by paracrine trafficking of AML exosomes
The study demonstrates that AML exosomes suppress hematopoiesis by altering stromal cells and progenitors. To model physiological hypoxia, AML cells were cultured in G-Rex in a low-oxygen chamber, which increased exosome release compared to normoxia.

Therapeutic bispecific T-cell engager antibody targeting the intracellular oncoprotein WT1
This study describes a BiTE derived from a TCR-mimic antibody against WT1. It induced T-cell cytotoxicity against WT1+ tumors and epitope spreading. Transduced EBV-specific T lymphocytes used in in vivo tracking studies were cultured in G-Rex.

Go-CART: an animal-free system for the assessment of CAR T cell function
The authors developed Go-CART, a six-chambered device to assess CAR T cell function without animals. The device features a gas-permeable base, allowing prolonged T cell-tumor interaction (>2 weeks) without medium replenishment, similar to G-Rex technology (co-author John Wilson is from Wilson Wolf).

Cancer Immunotherapy Based on Mutation-Specific CD4+ T Cells in a Patient with Epithelial Cancer
This study demonstrates that the immune system can mount a mutation-specific Th1 response against epithelial cancer. Adoptive transfer of enriched mutation-specific CD4+ TILs led to tumor regression. The provided excerpts do not explicitly mention the use of G-Rex devices.

Anti-leukemic potency of piggyBac-mediated CD19-specific T cells against refractory Philadelphia chromosome–positive acute lymphoblastic leukemia
This study generated CD19-specific CAR T cells using the piggyBac transposon system and expanded them in G-Rex 10 devices under serum-free conditions. This protocol produced clinically relevant numbers of CAR T cells that were effective against TKI-resistant Ph+ ALL cells.

Interleukin-7 mediates selective expansion of tumor-redirected cytotoxic T lymphocytes without enhancement of regulatory T-cell inhibition
This study demonstrates that CAR-redirected EBV-CTLs engineered to express IL-7Ra can be selectively expanded by IL-7 in the presence of Tregs. G-Rex were used to generate the expanded Tregs used in the suppression assays. This strategy enhances antitumor activity.

Adoptive transfer of rapidly-generated multivirus-specific T cells to treat Adv, EBV, CMV, BK and HHV6 infections of HSCT recipients
This abstract reports the clinical use of rapidly generated pentavalent virus-specific T cells expanded in G-Rex devices. The single-stimulation G-Rex protocol produced sufficient cells in 10 days to safely and effectively treat drug-refractory EBV, CMV, Adv, BK, and HHV6 infections in HSCT patients.
