Live cell imaging of SG formation under glutamine recovery and arsenite treatment. Movie of GFP-IGF2BP3 expressing U2OS cells imaged for 68 min every 4 min showing the formation of SG-positive cells over time in cells treated with amino acid starvation (EBSS)+VBL and glutamine followed by arsenite. Most cells form SGs. Bar 20 μm.
