Determination of optimal sodium (Na+) concentrations with in vitro cell viability assays: (A) LDH cytotoxicity assay, and (B) MTT cell viability assay performed on cultured human dermal fibroblast cells after 24 h. Na+ concentration in the control media was 150 mM. n = 6 wells/group. One-way ANOVA test was performed. Data are presented as mean ± SD. Authors state that the number of independent experiments in reference to cell viability (MTT assay) was 3, and that the one shown is 1 representative of the corresponding repeats.
