[Research Progress of HO1 on AntiOxidative Stress Injury of MSC --Review].

Mesenchymal stem cell (MSC) is widely used in cell therapy because of its high proliferative and multi directional differentiation potential as well as its low immunogenicity. The transplantation of MSC can help the repair of the injured organs, however, the MSC transplanted to the local organs are affected by oxidative stress and lead to premature aging or apoptosis. Heme oxygenase 1 (HO1) is a key ratelimiting enzyme in the process of heme metabolism, which has the functions of antiinflammation, antioxidation, antiapoptosis, antiaging, reducing cell damage and promoting angiogenesis. Induced high expression of HO1 in MSC could increase the ability of MSC against oxidative stress injury, delay the senescence and apoptosis of MSC, and alleviate cell injury. In this reviews, the research progress of HO1 on antioxidative stress injury of MSC.
