Tissue engineering has been rapidly developed in recent years to restore or replace the lost or malfunctioned tissues and organs. Biomaterials and scaffolds play an important role in tissue engineering to control cell functions and to modulate neo-tissue formation by mimicking the functional and structural characteristics of the native extracellular matrices. In this talk, I will introduce a few types of novel scaffolds developed by our group. The first type is hybrid scaffolds of synthetic polymers and naturally-derived polymers. Collagen sponge or microsponges were introduced in the pores or openings of mechanically strong synthetic polymer skeletons to construct the hybrid structures. The skeletons of synthetic polymers provided high mechanical strength, while the collagen sponge and mircosponges facilitated cell seeding and distribution. The hybrid scaffolds were used for cartilage tissue engineering. The second type is funnel-like collagen sponges that were prepared by using embossing ice particulates as a template. The funnel-like collagen sponges facilitated cell seeding, cell penetration, and distribution throughout the scaffold, and accelerated the regeneration of skin dermal tissue. The third type is biomimetic autologous ECM scaffold prepared by 3D culture of cells in a template that can be selectively removed after cell culture. The autologous ECM scaffolds showed excellent biocompatibility and can be used for tissue engineering to avoid any adverse host inflammatory and immune responses.
