Novel Epigallocatechin-3-Gallate (EGCG)-Loaded Mesoporous Bioglass Scaffolds for Bone Recruitment Applications

Abstract

Bioglass-based material has been widely used in the field of biomedical science. In this study, the proper concentration of epigallocatechin-3-gallate (EGCG) for a mesoporous bioglass (MBG) scaffold was determined based on the sponge replication method. The fabrication procedure performed using a foam exchange technique resulted in an interconnected network of pores scaffolds with no cracks. In the minimum bactericidal concentrations of the bacteria assessed, the antibacterial concentration of EGCG against E. coli (200 μg/mL) was higher than that against S. aureus (25 μg/mL). The MBG and EGCG-MBG scaffolds exhibited excellent apatite mineralization and drug release abilities (the highest cumulative drug release from the EGCG-MBG scaffold was 75.37%). Thus, a 200 μg/mL EGCG can prevent cell apoptosis and directly enhance cell proliferation. Hence, a low-dose EGCG-MBG scaffold is another option for bone recruitment material.

Solution-Based Processing for Scaffold Fabrication in Tissue Engineering Applications: A Brief Review

“…Natural biomaterials better support cell attachment, growth, and differentiation, since they induce a more positive response of the host tissue and do not produce harmful degradation products, enhancing the integration within the body [ 35 ]. Apart from these materials, solution-based manufacturing allows the exploitation of molecules to enhance cell activity [ 36 , 37 ]. Traditionally, ceramics, active agents, and growth factors were integrated within the formulated scaffolds for more rapid tissue growth or increased compatibility [ 4 ].…”
