Electron micrographs of biohybrid scaffold surfaces showed PEUU fibers spanned by dECM gel (A). The cross-sections of 80/20 (B), 72/28 (C) and 67/33 (D) PEUU/dECM wt% scaffolds were lamellar with regions rich in PEUU fibers and regions of dECM gel with fewer fibers. A magnified region from the 80/20 scaffold illustrates the presence of a PEUU fiber-rich lamella and less dense connecting fibers interspersed in the dECM material (red arrow points to fiber-rich region and blue arrows point to sparse fibers) (E). A simplified representation of the biohybrid scaffold architecture with lamellae enriched with PEUU fibers separated by dECM rich regions with interconnecting fibers (F).
