Extracellular Mg2+ concentration affects its transporters in a dose‐dependent manner. A) Representative confocal images showing cellular expressions of potential Mg transporters TRPM7, MagT1, and SLC41A1. Regions in red were enlarged in higher magnification. B) Effect of extracellular Mg concentrations on expression level of Mg transporters by quantitative fluorescent imaging analysis. (**P < 0.01, compare with 0 m; # P < 0.05, compare between groups; ## P < 0.01, compare between groups; n = 4). C) Western blot with quantitative analysis of TRPM7, MagT1, and SLC41A1 expression after exposure to a concentration gradient of Mg. (**P < 0.01, compare with 1 × 10−3 m; *P < 0.05, compare with 1 × 10−3 m; n = 3).
