Effects of Environmental pH on the Growth of Gastric Cancer Cells

Figure 2

Alkaline microenvironment promoted the apoptosis of GC cells. (a) Apoptosis of GC cells at different pH values (pH 6.0, pH 7.0, and pH 8.0) after being cultured for 48 h. A, B, and C in (a), respectively, represented apoptosis of SGC-7901 cultured in a medium with pH 6.0, pH 7.0, and pH 8.0 for 48 h, respectively; D, E, and F represented apoptosis of MKN45 cultured in a medium at pH 6.0, pH 7.0, and pH 8.0 for 48 h, respectively. (b) Apoptosis results of GC cells (SGC-7901 and MKN45) at media of different pH values (pH 6.0, pH 7.0, and pH 8.0) after being cultured for 48 h.
