CXCR4 antagonism. U20S cells expressing EGFP-CXCR4 were treated with either polymer alone (2.5 μg/mL) or polyplexes (DNA dose 0.5 μg/mL, w/w 5) for 30 min before incubation with 20 nM SDF-1. AMD3100 (300 nM) was used as a positive and PEI as a negative control. Results shown as mean antagonism ± SD (n = 3).
