This scientific poster presented at CIMT 2023 investigates glioblastoma, a WHO grade IV glioma and the most common primary adult brain tumor, and the expression of elevated levels of HLA-E that block NK cells with expression of the inhibitory NKG2A receptor, aiming to establish a large-scale ex vivo expansion of functional NKG2C+ NK cells.  Doing so from peripheral blood employing bottom-gas permeable membrane bioreactors (G-Rex) and using a recently developed PC-3 feeder cell line genetically engineered with IL-2, membrane-bound IL-15, as well as a first generation single chain trimeric HLA-E molecule.

This scientific poster investigates the kinetics of human T cell expansion in small scale G-Rex6M bioreactors using ScaleReady reagents. Data show the affect of seeding density on fold expansion, total cell yield, and phenotypic phenotypic composition of expanded T cells, including total and memory CD4⁺ and CD8⁺ cells.
