Generation of allogeneic CAR-NKT cells from hematopoietic stem and progenitor cells using a clinically guided culture method

The paper describes a feeder-free method to generate AlloCAR-NKT cells from HSPCs. G-Rex 6M well plates were used for the expansion stage (stage 4) of the NKT cell culture.

Neoantigen-specific stimulation of tumor-infiltrating lymphocytes enables effective TCR isolation and expansion while preserving stem-like memory phenotypes

The study introduces "NeoExpand" to selectively expand neoantigen-reactive TILs. It compares this to rapid expansion protocols (REP). G-Rex 24-well, 6-well, and 100 were used for the rapid expansion of T cells.

Assessment of the cytolytic potential of a multivirus-targeted T cell therapy using a vital dye-based, flow cytometric assay

This paper evaluates a flow cytometric cytotoxicity assay for multiVSTs. It highlights that multiVSTs, expanded in G-Rex 5M devices for 14 days, show potent cytolytic activity against viral targets that is better detected by this new assay than by chromium release.

Inosine Induces Stemness Features in CAR-T cells and Enhances Potency

The study shows that inosine induces stemness and metabolic reprogramming in CAR-T cells, improving potency. Clinical-scale manufacturing of GD2-CAR-T cells in inosine-containing media was performed using a semi-closed G-Rex system.

Antiviral cellular therapy for enhancing T-cell reconstitution before or after hematopoietic stem cell transplantation (ACES): a two-arm, open label phase II interventional trial of pediatric patients with risk factor assessment

A Phase II trial evaluating third-party VSTs for refractory viral infections in pediatric patients post-HSCT or with IEI. VSTs were expanded using a rapid expansion protocol in G-Rex-10 for 10 days. Clinical response rate was 62%.

Human 3D Ovarian Cancer Models Reveal Malignant Cell–Intrinsic and –Extrinsic Factors That Influence CAR T-cell Activity

The study uses 3D ovarian cancer models (spheroids, collagen gels, microfluidics) to study MUC1/TnMUC1 CAR T-cell activity. Resistance mechanisms and fibroblast interactions are explored. Transduced CAR T cells were cultured and expanded in G-Rex plates for 10 days.

A quality-by-design approach to improve process understanding and optimise the production and quality of CAR-T cells in automated stirred-tank bioreactors

This study uses Quality-by-Design (QbD) and Design of Experiments (DOE) to optimize CAR-T expansion. Small-scale DOE studies were conducted in G-Rex 24-well plates to identify optimal parameters (single activation, short seed train), which were then translated to Ambr 250 bioreactors.

Selection, engineering, and in vivo testing of a human leukocyte antigen–independent T-cell receptor recognizing human mesothelin

The study describes a mesothelin-specific HLA-independent TCR (HiT) that activates T cells and kills tumor cells in vitro and in vivo. Large-scale T-cell transduction and expansion were performed using G-Rex 6M plates.
