COMPARISION OF THE GLIO-PROTECTIVE EFFECTS OF BIOPOLYMER COATED ELECTROSPUN SCAFFOLDS

Abstract

Gliosis is a condition that plays a negative role in various neurological pathologies. In this study, it was aimed to obtain and compare the glio-protective effects of electrospun fibrous scaffolds coated by different biopolymers. First, in vitro gliosis model was obtained by inducing U-87 MG cells with LPS and IFN-γ. The optimized model was applied to U-87 MG cells grown on polycaprolactone (PCL), hyaluronic acid (HA) coated, gelatin coated, and collagen coated PCL scaffolds. Immunofluorescent (IF) staining was performed with glial fibrillary acidic protein (GFAP) antibody to determine the level of gliosis. It was found that 5µg/mL LPS concentration induced gliosis and hyaluronic acid-coated PCL scaffolds have shown a protective effect on gliosis.
