HIF1A and myocardial infarction: It is previously reported that infusion of MSC overexpressing HIF‐1α promotes myocardial healing in an experimental rat model of myocardial infarction.19 As described in previous studies, signalling pathways related to several paracrine factors and interleukins are up‐regulated in HIF‐MSCs.20 In this study, we reported that hypoxia increased chemotaxis migration of MSCs.
