Oxidative stress (OS) occurs when the production of reactive oxygen species (ROS) is not balanced by the body's antioxidant defense system. OS can profoundly affect cellular health and function. ROS can have a profound negative impact on cells that undergo a predestined and time-regulated process of proliferation or differentiation, such as perinatal stem cells. Due to the large-scale employment of these immunotolerant stem cells in regenerative medicine, it is important to reduce OS to prevent them from losing function and increase their application in the regenerative medicine field. This goal can be achieved through a variety of strategies, such as the use of antioxidants and other compounds that can indirectly modulate the antioxidant defense system by enhancing cellular stress response pathways, including autophagy and mitochondrial function, thereby reducing ROS levels. This review aims to summarize information regarding OS mechanisms in perinatal stem cells and possible strategies for reducing their deleterious effects.
氧化应激(OS)是指当活性氧(ROS)的产生不能被机体的抗氧化防御系统平衡时发生的一种状态。OS 会严重影响细胞的健康和功能。ROS 可能对经历预定和时间调节的增殖或分化过程的细胞产生深远的负面影响,例如围产期干细胞。由于这些免疫耐受的干细胞在再生医学中的广泛应用,降低 OS 以防止其功能丧失并增加其在再生医学领域的应用至关重要。这一目标可以通过多种策略来实现,例如使用抗氧化剂和其他化合物,通过增强细胞应激反应途径,包括自噬和线粒体功能,间接调节抗氧化防御系统,从而降低 ROS 水平。本综述旨在总结围产期干细胞中 OS 机制的信息以及减少其有害影响的可能策略。
