Generation of tumor antigen-specific T cell lines from pediatric patients with acute lymphoblastic leukemia – implications for immunotherapy
This study demonstrates the generation of T-cell lines targeting WT1, Survivin, MAGE-A3, and PRAME from pediatric ALL patients using autologous DCs and PHA-blasts. The cells showed specific anti-leukemic activity. G-Rex are referenced as a strategy for scaling up to clinical cell numbers.

Antigen Presenting Cell-Mediated Expansion of Human Umbilical Cord Blood Yields Log-Scale Expansion of Natural Killer Cells with Anti-Myeloma Activity
This study utilized G-Rex to expand NK cells from cord blood using artificial antigen presenting cells (aAPCs). The protocol achieved a mean 2389-fold expansion of high-purity NK cells in 14 days. Expanded cells demonstrated significant in vitro and in vivo cytotoxicity against multiple myeloma.

Safety and clinical efficacy of rapidly-generated trivirus-directed T cells as treatment for adenovirus, EBV, and CMV infections after allogeneic hematopoietic stem cell transplant
This study reports a simplified method to generate T cells targeting EBV, CMV, and Adenovirus using nucleofected dendritic cells and G-Rex devices. The 10-day G-Rex protocol produced clinically relevant cell numbers. Infused cells were safe and effective against active viral infections in HSCT recipients.

Improved Homing to Bone Marrow, Spleen and Lung of Adoptively Infused NK Cells Expanded Ex Vivo with the Small Molecule Nicotinamide Using Feeder-Free Conditions
This study demonstrates that nicotinamide (NAM) enhances the homing and retention of NK cells in bone marrow, spleen, and lung. NK cells were expanded in G-Rex devices under feeder-free conditions with IL-2 or IL-15. The G-Rex platform supported large-scale expansion, yielding high-purity NK cells.

Randomized Selection Design Trial Evaluating CD8+-Enriched Versus Unselected Tumor-Infiltrating Lymphocytes for Adoptive Cell Therapy for Patients With Melanoma
Compares unselected young TILs vs CD8+-enriched TILs. Mentions that G-Rex were optimized for TIL therapy and introduced for clinical use. The study used (WAVE and G-Rex) for high-density T-cell expansion, facilitating rapid accrual
Publications
Robust and cost effective expansion of human regulatory T cells highly functional in a xenograft model of graft-versus-host disease
Describes a protocol for expanding nTregs using G-Rex10 and G-Rex100 devices. The method yielded >10^9 Tregs in 21 days with high purity and suppressive function. G-Rex promoted robust expansion (over 600-fold) compared to 24-well plates (5-6 fold) and maintained telomere length
