Page 557. Recently, we found the misuse of the MitoSOX images in the control and LPS+SER@TPP@CUR group in our paper. Two images in Figure 4 were actually the result of the cell uptake experiment labeled by the fluorescent probe. Due to the similarity of the images and the author’s negligence caused by looking at the picture for a long time, some wrong pictures were collated.
The corrected Figure 4 is presented below.
Figure 4.
Time-dependent cellular uptake and mitochondrial colocalization of Ser@TPP@CUR on HK-2 cells in vitro. (a) Representative fluorescence images of time-dependent cellular uptake of Ser@TPP@CUR by HK-2 cells with or without LPS treatment. (b) Flow cytometry results for cellular uptake (2.0 h) of Ser@TPP@CUR by HK-2 cells with or without LPS treatment. (c) Representative fluorescence images of Ser@TPP@CUR (green) with KIM-1 receptors (red) on HK-2 cells. Free CUR was used as the control. (d) Flow cytometry results for cellular uptake of Ser@TPP@CUR by HK-2 cells treated with different concentrations of free Ser. (e) Representative fluorescence images of Ser@TPP@CUR with MitoTracker Red on HK-2 cells. Free CUR was used as the control.
