Core Tip For the first time, we established a model of the intracellular pH (pHi) regulation mechanism in human induced pluripotent stem cells (hiPSCs). The steady-state pHi value of hiPSCs was 7.50-7.68, which greater than that of normal adult cells. The Na+-H+ exchanger, the Na+-HCO3- cotransporter and vacuolar-ATPase were the main acid extruders, while the Cl--HCO3- anion exchanger and the Cl--OH- exchanger were the main acid loaders. Moreover, the pHi and acid-extruding mechanism were decreased during the loss of pluripotency in hiPSCs. pHi regulators represent an attractive target for differentiation efficiency or culture quality.
