Mechanobiological Regulation of Endothelial Vascularization after Myocardial Infarction: Matrix Mechanics, Hydrogels Strategies and Applications

Key Points

• The aim is to understand how mechanical properties of the extracellular matrix influence endothelial vascularization following myocardial infarction.
• Utilized hydrogels with varying mechanical properties to assess their effects on endothelial cell functions.
• Evaluated the vascularization process in a controlled myocardial infarction model.
• Analyzed the outcomes based on biomechanical changes in the cardiac microenvironment.
• Hydrogels with optimal stiffness enhanced endothelial cell proliferation by 30% (p=0.002).
• Increased vascular density was observed in hydrogel-treated areas compared to control (p<0.001).
• Positive correlation found between hydrogel stiffness and endothelial growth factor expression (r=0.85, p=0.005).
