Joint Research Laboratory (TOPPAN) for Advanced Cell Regulatory Chemistry carries out a cooperative research between laboratory of Industrial Organic Chemistry at graduate school of engineering, Osaka University and TOPPAN Printing CO., Ltd. We are going to develop and commercialize a novel cell regulation technology. In this laboratory, we focus on interaction between cell and synthetic polymer, natural polymer or protein to control cell adhesion, differentiation, proliferation, self-assembly and so on. In addition, we will apply these technologies to 3D tissue construction. 3D tissues are expected to be useful for high throughput drug assays and regenerative medicine.
