Correction to “Effect of Cell Age on Uptake and Toxicity of Nanoparticles: The Overlooked Factor at the Nanobio Interface”

Figure 1.(A) Fluorescence micrograph of IMR90 cells treated BrdU based cell proliferation assay.(B) Fluorescence micrograph of CCD841CoN cells treated BrdU based cell proliferation assay.(C) Quantification of cell proliferation.BrdU based cell proliferation in the cultures was detected by immunofluorescence.Scale bar = 50 μm.(D) Bright field micrograph of IMR90 cells in the SA-ß-gal assay.(E) Bright field micrograph of CCD841CoN cells in the SA-ß-gal assay.(F) Quantification of SA-ß-galactosidase expression.SA-ß-Galactosidase activity in the cultures was cytochemically detected at pH 6. Scale bar = 100 μm.(G) Fluorescence micrograph of IMR90 cells in the SAHF assay.(H) Fluorescence micrograph of CCD841CoN cells in the SAHF assay.(I) Quantification of SAHF formation.SAHF formation in cultures was detected by Hoechst 33342 nuclear staining.Scale bar = 10 μm.Control: young IMR90 and CCD841CoN cells.Data are represented as mean ± SD n = 6 for each group.Significant differences are marked as asterisks (*).* P < 0.05, ** P < 0.01, and *** P < 0.001.(n.s.) not significant.
