Abstract

Abstract In this work, an innovative and easy method for the fabrication of 3D scaffold from 2D electrospun structures is introduced. For this aim, coral microparticles were fixed inside the nanofibrous PCL/Gelatin mat and the obtained structure was post assembled into a cylindrical design. Scaffold fabrication procedure is described in detail and morphological properties, physical and mechanical characteristics and in vitro assessments of the prepared scaffold are reported. Presences of coral microparticles in the structure led to the formation of empty spaces (3D pores) between nanofibrous layers which in turn prevent the compact accumulation of nanofibers. Post-assembly of the obtained nanofibrous coral-loaded structures makes it possible to prepare a scaffold with any desired dimension (diameter and height). Existence of coral particles within the nanofibrous mats resulted in distant placement of layers toward each other in the assembling step, which in turn create vacancy in the structure for cellular migration and fluid and nutrients exchange of the scaffold with the surrounding environment. Cell morphology within the scaffolds is investigated and cytotoxicity and cytocompatibility of the structure is evaluated using Alamar blue assay. Enhancement in mineralization of the seeded cells within the prepared coral-loaded scaffolds is demonstrated by the use of SEM-EDX. Performed compression mechanical test revealed excellent modulus and stiffness values for the cylindrical samples which are comparable to those of natural bone tissue.
