Effects of environmental pH (~ 8.0) and exogenous Mg2+ (~ 40 μg/ml) on macrophage behavior compared to those under normal culture medium condition (pH at ~ 7.4 and Mg2+ concentration at ~ 19.2 μg/mL): cell a morphology and b viability; inflammation-related gene expressions in macrophages in response to c environmental pH and d exogenous Mg2+. * p < 0.05 and ** p < 0.01 compared to the control
