Ganoderic Acid D Protects Human Amniotic Mesenchymal Stem Cells against Oxidative Stress-Induced Senescence through the PERK/NRF2 Signaling Pathway

<div>GA-D significantly reduced the generation of <i>β</i>-galactosidase. (a) The effect of different concentrations of GA-D on H<sub>2</sub>O<sub>2</sub>-induced premature senescence in hAMSCs by <i>β</i>-galactosidase staining; 0.1% DMSO group was used as a solvent
