WebMar 30, 2024 · Rationale: The promising clinical benefits of delivering human mesenchymal stem cells (hMSCs) for treating heart disease warrant a better understanding of underlying mechanisms of action. hMSC exosomes increase myocardial contractility; however, the exosomal cargo responsible for these effects remains unresolved. Objective: This study … WebContractility is the inherent strength and vigour of the heart's contraction during systole. According to Starling's Law, the heart will eject a greater stroke volume at greater filling pressures. For any filling pressure (LAP), the stroke volume will be greater if the contractility of the heart is greater. The inherent strength and vigour of ...
