Allogeneic Mesenchymal Stromal Cells Overexpressing Mutant Human Hypoxia‐Inducible Factor 1‐α (HIF1‐α) in an Ovine Model of Acute Myocardial Infarction

Abstract

Intramyocardial delivery of BMMSC-HIF reduced infarct size and improved LV systolic performance compared to BMMSC, attributed to increased neovascularization and cardioprotective effects induced by HIF1-mediated overexpression of paracrine factors and enhanced retention of injected cells. Given the safety of the minicircle vector and the feasibility of BMMSCs for allogeneic application, this treatment may be potentially useful in the clinic.
