during the process of endothelialization, are well-coated with gelatin. This coating will be essential for promoting endothelial cell attachment, proliferation, and subsequent formation of a functional endothelial cell layer on the vascular graft. The micro-CT images confirm that the scaffold maintains a robust structural integrity with well-integrated layers. However, the stability of the gelatin coating under physiological conditions is a crucial factor for the long-term functionality of the graft. Gelatin is known to undergo hydrolytic degradation when exposed to aqueous environments, which can impact its effectiveness as a coating over time, particularly in maintaining hemocompatibility and supporting endothelialization. This underscores the necessity for stable gelatin coatings. Recent studies have demonstrated the stability of the gelatin coating, enhanced through a dopamine coating intermediate, exhibited coating stability for up to 24 days, promoting the attachment and spreading of endothelial cells and smooth muscle cells . The distinct layers suggest that the multiple fabrication processes-3D printing, electrospinning, and gelatin coatingwere successfully combined to create a cohesive scaffold. Other studies utilizing multiple fabrication techniques, such as Electrospinning, Braiding, and Thermally Induced Phase Separation, have also demonstrated strong endothelialization, excellent mechanical properties, and reliable biocompatibility, further highlighting the potential of combining diverse methods to closely replicate the structure and function of natural blood vessels .
