This video demonstrates the in vitro differentiation of granulocyte-macrophage-colony-stimulating factor or GM-CSF-producing T helper cells (THGM). Isolated naïve T cells are stimulated for differentiation into THGM, which is confirmed by detecting high intracellular GM-CSF production and a low expression of other T helper cell-specific cytokines.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Reagent and Material Preparation Prepare 500 mL of phosphate-buffered saline (PBS) containing 2% fetal bovine serum (FBS) and 1 mM ethylenediaminetetraacetic acid (EDTA). NOTE: Keep the buffer on ice throughout the whole procedure for optimal results. Prepare 50 mL of complete RPMI medi…
