Co-culturing of JB6pcDNA5/FRT TRAIL with native T cells. a Phase-contrast-imaging of a apoptotic CD4⁺ cell after 48 hours of co-culture with JB6-pcDNA5/FRT TRAIL. b Annexin V/Propidiumiodide dyed CD4⁺ cell after 48 hours of co-culture with JB6-pcDNA5/FRT TRAIL. Membrane fluorescence is characteristic for apoptosis. c Phase-contrast-imaging of a CD8⁺ cell after 48 hours of co-culture with JB6-pcDNA5/FRT TRAIL. d Annexin V/Propidiumiodide dyed CD8⁺ cell after 48 hours of co-culture with JB6-pcDNA5/FRT TRAIL.
