Figure 3. Media pH and Mg ion concentrations in the media collected at every 24 hours after hESCs were cultured with M-Mg and D-Mg for 72 hours.

Figure 3

(A) The average pH and (B) the average magnesium ion concentrations (**p<0.05 compared to M-Mg). Values are mean ± standard deviation: n = 3. The average pH and Mg ion concentrations for the culture with both Mg samples significantly increased as compared with the control without Mg samples. The statistically significant lower pH of the post-culture media with D-Mg was detected in comparison with M-Mg. Furthermore, after 24 hours, a general trend of gradual decrease in average pH and magnesium ion concentrations over time was observed for both Mg samples. (**p<0.05 compared to M-Mg). Values are mean ± standard deviation: n = 3.
