Figure 6. Effect of endogenous ATP and serum on PSCs proliferation.

Figure 6

A. Comparison of the DNA incorporation in WT and KO PSCs with and without 5 U/ml apyrase. All samples contained 1% serum (n = 9–23). Y-axis shows the BrdU incorporation in relative light units. In the presence of apyrase, there was no significant difference between proliferation of WT and KO cells. Significant difference (P<0.05) from respective controls (#) and between WT and KO (*) is indicated. B. Effect of serum on DNA incorporation in WT PSCs. Significant difference (P<0.05) from 1% serum controls (#) and between 0% and 0% serum with 5 mM ATP (§) is indicated.
