The Protective Effect of Indole-3-Acetic Acid (IAA) on H2O2-Damaged Human Dental Pulp Stem Cells Is Mediated by the AKT Pathway and Involves Increased Expression of the Transcription Factor Nuclear Factor-Erythroid 2-Related Factor 2 (Nrf2) and Its Downstream Target Heme Oxygenase 1 (HO-1)

Effect of H2O2 on human dental pulp stem cells (hDPSCs). (a) The viability of hDPSCs was also assessed after treating the cells with different concentrations of H2O2 ranging from 1 to 400 μM. The viability of hDPSCs decreased after treatment with 180 μM and higher concentrations of H2O2. (b) Morphologies of hDPSCs cultured with 0 μM (nontreated group, NT), 150 μM, and 180 μM H2O2. , .
