Fluorescence observation of calcium influx in the differentiated PC12 cells stained by different molecular probes. (a) The fluorescence images of the differentiated PC12 cells induced by Aβ1-42 after the incubation with TP or MC-PLGA-TP-NP for 48 h. (b) Statistic data for the mean relative fluorescent intensity (MRFI) calculated by MetaMorph software. The experiment was repeated five times, and data were represented as the (). The scale bar represented 20 μm. Significant difference (, versus TP).
