Figure 1. Impairment of dye uptake by gap junction inhibitors in NRVMs.

(A) Typical confocal images of Lucifer yellow (LY) uptake in different groups of single and confluent NRVMs treated with DMSO or heptanol (1 or 1.5 mM) for 2 min, Gap 27 (300 µM) for 30 min and FFA (25 µM) for 5 min as indicated. (B, C) Statistical data were obtained from 6–8 independent determinations for each bar. * and ** represent P<0.05 and P<0.01, vs. DMSO, respectively.
