Reactive oxygen species (ROS) are multifunctional gas transmitters with diverse biological actions (adverse vs beneficial) dependent on their level. The differentiation of vascular stem cells into smooth muscle cells (SMCs) might be involved in the pathogenesis of cardiovascular disorders including hypertension and atherosclerosis. Therefore, controlling the differentiation of vascular stem cells is a potential strategy for the treatment of vascular diseases. Nonetheless, it remains to be revealed whether ROS could mediate the differentiation of mesenchymal stem cells (MSCs) into SMCs. In addition, there are no redox (reduction–oxidation)‐sensitive molecules identified, which are responsible for the ROS‐induced differentiation of MSCs. In article number 1700208, Baek et al. [ Proteomics 2017, 17 , Issue 21] found that ROS mediate the differentiation of MSCs into SMCs through the modification of redox states of a multifunctional ROS‐responsive protein, DJ‐1, revealing a novel regulatory mechanism for differentiation of MSCs into SMCs and shedding light into the future development of stem‐cell‐targeted pharmacotherapy.
