Preclinical Evaluation of 89Zr-Df-IAB22M2C PET as an Imaging Biomarker for the Development of the GUCY2C-CD3 Bispecific PF-07062119 as a T Cell Engaging Therapy
This study evaluates 89Zr-Df-IAB22M2C PET imaging to track CD8+ T cells in a colorectal cancer model treated with a GUCY2C-CD3 bispecific antibody. G-Rex® devices were used to expand human T cells prior to adoptive transfer. The tracer effectively monitored dose-dependent T cell infiltration.

Microfluidic transfection of mRNA into human primary lymphocytes and hematopoietic stem and progenitor cells using ultra‑fast physical deformations
The study presents a microfluidic device (VECT) for mRNA delivery into primary T cells, NK cells, and HSPCs. G-Rex® plates were used for the culture of NK cells during the expansion phase. The method achieved high transfection efficiency and viability without compromising cell function.

RNA-Seq Analysis Reveals CCR5 as a Key Target for CRISPR Gene Editing to Regulate In Vivo NK Cell Trafficking
RNA-seq revealed that ex vivo expansion alters chemokine receptor expression in NK cells, notably upregulating CCR5. G-Rex® were used to expand NK cells with feeder cells. CRISPR-mediated CCR5 disruption reduced liver trafficking and increased NK cell presence in circulation in mice.

Identification of New Cytokine Combinations for Antigen-specific T cell Therapy Products via a High Throughput Multi-parameter Assay
A high-throughput assay identified optimal cytokine combinations for viral-specific T cell (VST) expansion. The study validated that IL15/IL6 culture conditions in G-Rex®10 gas-permeable devices produced VSTs functionally equivalent to standard IL4/IL7 conditions. This method streamlines process development.

“Cerberus” T Cells: A Glucocorticoid-Resistant, Multi-Pathogen Specific T Cell Product to Fight Infections in Severely Immunocompromised Patients
The authors generated "Cerberus" T cells (Cb-STs) targeting multiple viruses and Aspergillus fumigatus, with CRISPR/Cas9-mediated glucocorticoid receptor disruption. G-Rex®10 devices were used for the culture and expansion of these multi-pathogen specific T cells. Cb-STs maintained function in the presence of dexamethasone.

Non-transplantable cord blood units as a source for adoptive immunotherapy of leukaemia and a paradigm of circular economy in medicine
This study repurposes non-transplantable umbilical cord blood units to generate myeloid dendritic cells (DCs) and bivalent-leukemia-specific T cells. G-Rex® were used to expand DCs from CD34+ cells, facilitating scalable production. The generated T cells showed specificity against WT1 and PRAME.

Enzymatically produced piggyBac transposon vectors for efficient non-viral manufacturing of CD19-specific CAR T cells
The study presents a manufacturing platform for CD19-specific CAR T cells using enzyme-produced piggyBac transposon DNA and mRNA transposase. G-Rex®10 were utilized for large-scale expansion, yielding up to 10^8 CAR-T cells per electroporation. The method allows precise control of vector copy number.

Freezing Medium Containing 5% DMSO Enhances the Cell Viability and Recovery Rate After Cryopreservation of Regulatory T Cell Products ex vivo and in vivo
This research optimizes cryopreservation strategies for regulatory T cell (Treg) products. G-Rex® were used for the culture and expansion of Treg cells and for transporting fresh nTreg products. Results show that a freezing medium with 5% DMSO significantly improves cell viability and recovery.

Differentiation of natural killer cells from induced pluripotent stem cells under defined, serum- and feeder-free conditions
This study evaluates differentiating NK cells from iPSCs under chemically defined, serum-free conditions without feeder layers. G-Rex® plates were used to expand hiPSC01-derived NK cells and peripheral blood NK cells for 2 weeks, achieving high fold expansion. The method yields functional, cytotoxic NK cells.
