The development of injectable biomaterials is attractive because these materials are performed in a minimally invasive manner which significantly accelerates wound healing, improves patient comfort and satisfaction. As a cell carrier, the injectable biomaterials can readily fit any irregular shapes of defects. When they act as a drug carrier, the injectable biomaterials can modulate temporal- and spatial-release of drugs to control cellular response in focal areas. A number of naturally- and synthetically-based biomaterials have been designed and tested for tissue regeneration in recent years. However, novel injectable biomaterials are still needed with improved properties (mechanical strength, biocompatibility, vascularization, et.al) for clinical application. This session will focus on the developments of novel injectable biomaterials for tissue regeneration and drug delivery. Specific interests will be given to novel injectable biomaterials design, synthesis, cell/drug delivery, and their applications to tissue regeneration.
