Shape Retaining and Sacrificial Molding Fabrication Method for ECM-Based in vitro Vascular Model

摘要

This paper describes a new fabrication method for the extracellular matrix (ECM)-based in vitro vascular model. The vascular model was fabricated with shape retaining mold and sacrificial mold (shape retaining and sacrificial molding, SRS-molding). We compared SRS-molding and sacrificial molding. In addition, complex mechanical stimuli such as stretching and flowing in the branches of the vascular model were analyzed by simulation software. Finally, we performed the perfusion culturing with our vascular model and stretching them. Our vascular model and mechanical stimuli analysis would elevate the vascular culturing to the next step.
