Abstract

Abstract: Glass sheets covered with aligned electrospun silk fibroin ( Bombyx mori ) were compared to tissue culture‐treated Thermanox® coverslips, using an organotypic culture method. Different chick embryo organ behaviours were analysed in terms of circularity, cell growth and cell adhesion after being cultivated in contact with these two materials. The circularity (cell layer shape corresponding to the trend of the biomaterials to induce a specific directionality) depends on the organ used when in contact with silk fibroin. This biomaterial induced higher cell adhesion (kidney) or lower cell adhesion (spine) compared to Thermanox. Cell growth, represented by the cell layer area (mm 2 ), was also drastically reduced (gonad) or increased (blood vessel) on the silk fibroin. Organotypic culture is a rapid, cost effective and relatively simple method to evaluate different parameters, allowing prescreening of morphology and cytocompatibility to select the appropriate applications for new biomaterials. In the present study we compared the morphology of different organotypic cultures on orientated silk and Thermanox as growth supports to rapidly evaluate the benefit of a silk‐based biomaterial for tissue engineering.
