Impact of cryopreservation on CAR T production and clinical response

This study evaluates the impact of cryopreservation on CAR T cell production. Cells were expanded in G-Rex100, which facilitated simple media top-ups. The study found that cryopreserved PBMCs and CAR T products yielded comparable expansion and clinical responses to fresh materials.

Rapid Generation of TCR and CD8ab Transgenic Virus Specific T Cells for Immunotherapy of Leukemia

The authors describe a method to generate TCR and CD8ab transgenic VSTs using IFN-g cytokine capture. G-Rex devices were utilized for the second stimulation expansion phase, yielding high numbers of polyfunctional T cells with simultaneous anti-viral and anti-tumor activity in a shortened timeframe.

Potent, Selective CARs as Potential T-Cell Therapeutics for HPV-positive Cancers

The authors engineered high-potency CARs targeting HPV E6 peptide-MHC complexes. Primary T cells transduced with these CARs were expanded in 24-well G-Rex plates supplemented with IL-2. The optimized CARs showed comparable sensitivity and selectivity to clinical TCRs in cytotoxicity assays.

Using Allogeneic, Off-the-Shelf, Sars-Cov-2-Specific T Cells to Treat High Risk Patients with COVID-19

This study explores generating banked SARS-CoV-2-specific virus-specific T cells (VSTs) for immunocompromised patients. The manufacturing process utilized G-Rex devices with activating cytokines to produce Th1-polarized, polyfunctional T cells capable of selectively killing viral antigen-expressing targets.

CAR-NK Cells Effectively Target SARS-CoV-2-Spike-Expressing Cell Lines In Vitro

The authors developed CAR-NK cells using the S309 antibody to target SARS-CoV-2. Primary S309-CAR-NK cells were expanded in G-Rex plates for 21 days following transduction. These cells demonstrated effective binding and killing of spike-protein expressing target cells in vitro.

GMP-Compliant Universal Antigen Presenting Cells (uAPC) Promote the Metabolic Fitness and Antitumor Activity of Armored Cord Blood CAR-NK Cells

This study describes the use of universal antigen presenting cells (uAPC) to expand cord blood CAR-NK cells. G-Rex (M100 series) were used for GMP-grade expansion, enabling a closed system with optimal gas exchange. The process achieved robust expansion and enhanced antitumor activity of the NK cells.

Self-organized emergence of hyaline cartilage in hiPSC-derived multi-tissue organoids

This study reports the spontaneous generation of hyaline cartilage in hiPSC-derived multi-tissue organoids (MTOs) using a xeno- and feeder-free protocol. G-Rex100 were used to culture organoids for up to 30 weeks, overcoming hypoxia limitations. RNA-seq links cartilage formation to BMP signaling.

DL4-μbeads induce T cell lineage differentiation from stem cells in a stromal cell-free system

The authors developed DL4-conjugated microbeads to induce T cell differentiation from CD34+ stem cells without stromal cells. The system was adaptable to G-Rex plates for scalable production. It successfully generated proT cells capable of thymic engraftment and maturation.

Inhibition of MEK pathway enhances the antitumor efficacy of chimeric antigen receptor T cells against neuroblastoma

This study investigated combining GD2-CAR T cells with the MEK inhibitor trametinib for neuroblastoma. PiggyBac-generated CAR-T cells were expanded in G-Rex 6-well plates. The combination improved antitumor efficacy in vivo, overcoming MEK inhibitor-induced T cell suppression seen in vitro.

Immunogenic chemotherapy enhances recruitment of CAR-T cells to lung tumors and improves anti-tumor efficacy when combined with checkpoint blockade

This study used a KPROR1 lung cancer model to show that immunogenic chemotherapy (Ox/Cy) enhances ROR1 CAR-T cell infiltration. Clinical human ROR1 CAR-T cells were expanded in G-Rex. The combination of Ox/Cy, CAR-T, and anti-PD-L1 improved survival.
