In our study, the mechanical compliance of hierarchical structures, as presented in Figure measured approximately 10 %/100 mmHg before coating and increased to 12%/100 mmHg after gelatin coating. The compliance tests demonstrated that the scaffold maintained its structural integrity over time under conditions simulating the high shear stress and cyclic loading typical of the arterial system. Notably, while some fiber deformation occurred in samples without the gelatin coating-likely due to the penetration of the solution into the fibers-the gelatin-coated samples exhibited no significant changes in their structure.
