Professor Guoping Chen at the National Institute for Materials Science in Japan was invited to make a report themed: Challenges in Biomaterials and Tissue Engineering Research at Polymer Building on August 13, 2013. The report included the following four aspects: 1. Stepwise tissue development-mimicking matrices; 2. Cultured cell-derived matrix scaffolds; 3. Funnel-like porous scaffolds with open surface pores; 4. Hybrid porous scaffolds. After the report, students had a warm response and actively asked questions, and Professor Chen answered these questions patiently.
