Cover Story: Cell-based therapies for myocardial infarction have shown promise, including those using cardiac ckit+ progenitor cells. The benefits of cell therapies have more recently been attributed to paracrine signaling, specifically through small extracellular vesicle (sEV) release. Despite being cardioprotective, the potency of sEV-therapies is limited because of low and variable cargo encapsulation, inconsistent sEV release, and dependence on the parent cell. Here, we engineer sEV-like vesicles (ELVs) to maintain the benefits of sEVs but allow for tunable and selective cargo encapsulation. We confirm ELV structure and characterization against sEVs and show similar uptake by endothelial cells. Finally, we show that miR-126+ELVs increase endothelial cell tube formation compared to sEVs.
