Reactive Oxygen Species Are Required for Human Mesenchymal Stem Cells to Initiate Proliferation after the Quiescence Exit

Effect of various antioxidants on the endometrial (a) and adipose (b) mesenchymal stem cell proliferation. NAC (20 mM), Tempol (1 mM), and Resveratrol (20 μM) were added to the cell medium 6 h after activation of the synchronized cell proliferation; cell cycle analysis was performed 24 h after activation.  h: the moment of the activation of cell proliferation; eMSC: endometrial mesenchymal stem cells; adMSC: adipose mesenchymal stem cells. All data are presented as mean ± SD ().
