NIPA2 expression and mitophagy in primary osteoblasts. (A) Immunofluorescence showing ALP expression in primary osteoblasts of each group. (B) ALP staining images of primary osteoblasts in WT and db/db groups. (C) Immunofluorescence of NIPA2 in primary osteoblasts of WT and db/db groups (values are presented as the mean ± SD; *P < 0.05 vs. WT, n = 30 cells from three independent experiments). (D) Detection of magnesium fluorescence in primary osteoblasts of WT and db/db groups (values are presented as the mean ± SD; *P < 0.05 vs. WT, n = 30 cells from three independent experiments). (E) TEM shows the number of mitophagosomes in primary osteoblasts of WT and db/db groups (scale bars, 1 μm and 2 μm. n = 3 per group. Values are presented as the mean ± SD *P < 0.05 vs. WT).
