Expression of Mt-related factors, ROS production, and expression of protein and glucose transporters in NRK-52E cells following the addition of BM-MSC-Mt or Mt isolated from NIH-3T3 cells (3T3-Mt). NRK-52E cells were cultured in low glucose (LG) or high glucose (HG) conditions. (a) Expression of Bcl-2 and Bax in NRK-52E cells. Cropped images of immunoblots are shown; full-length blots are shown in Supplementary Fig. S7b. (b) Immunofluorescence images of PGC-1α (green) in NRK-52E cells. Nuclei are counterstained with DAPI (blue). Scale bar, 25 μm. (c) Fluorescence images of ROS production in NRK-52E cells. Nuclei are counterstained with DAPI (blue). Scale bar, 25 μm. Quantification of ROS production is shown in the right panel as the mean ± s.e.m. (n = 10 images per group). *P < 0.05 LG vs. HG-none; †P < 0.05 HG-none vs. HG-MSC-Mt using ANOVA corrected with the Bonferroni coefficient. (d) Immunofluorescence images of megalin (green) in NRK-52E cells. Nuclei are counterstained with DAPI (blue). Scale bar, 25 μm. Quantification of megalin expression is shown in the right panel as the mean ± s.e.m. (n = 10 images per group). *P < 0.05 LG vs. HG-none, LG vs. HG-MSC-Mt, and LG vs. HG-3T3-Mt; †P < 0.05 HG-none vs. HG-MSC-Mt, and HG-none vs. HG-3T3-Mt; ‡P < 0.05 HG-MSC-Mt vs. HG-3T3-Mt using ANOVA corrected with the Bonferroni coefficient. (e) Immunofluorescence images of SGLT2 (green) in NRK-52E cells. Nuclei are counterstained with DAPI (blue). Scale bar, 25 μm. Quantification of SGLT2 expression is shown in the right panel as the mean ± s.e.m. (n = 10 images per group). *P < 0.05 LG vs. HG-none, and LG vs. HG-MSC-Mt; †P < 0.05 HG-none vs. HG-MSC-Mt using ANOVA corrected with the Bonferroni coefficient.
