A reproducible method for the expansion of mouse CD8+T lymphocytes

Murine adoptive CD8+ T-cell immunotherapy studies require the generation of large numbers of high viability CD8+ cells. Here we report a tissue culture protocol for the reliable expansion of CD8+ T-cells derived from murine spleen to give a 20-fold expansion after 4 days in culture. The cells were transfected with an mRNA GFP construct and transferred into NOD mice. GFP positive cells could be detected 7 days after transfer thus confirming that the cells survive and are functional for up to 1 week. (C) 2015 The Authors. Published by Elsevier B.V.
