Schematic of (a) VSMC sheet harvesting via enzymatic degradation of hydrogel substrate as monolayer and (b) VSMC sheet stacking strategy to fabricate bilayer. (c) Schematic showing bilayer VSMC patches mechanical stretching model. Reference vector (V1, V2) indicating two collagen fiber family orientation with respect to the stretching direction (x). A finite element model was developed to simulate uniaxial tensile testing of bilayer VSMC patches. Top panel: undeformed, bottom panel: deformed.
