DOF Inc. bio business started to recognize the reality of domestic patients suffering from inactivation of the domestic tissue donation culture, transplant tissue projects that rely on the import market, and lack of transplant tissue supply. In order to supply stable domestic transplant tissue, DOF Inc. has been trying to provide the best eco-friendly products and solutions based on biological materials-based supercritical technology through heterogeneous fusion of chemical engineering and biotechnology, and it is gradually paying off. Based on this, we will develop bio-products such as transplant human tissue, cartilage therapy, tissue-based exosomes, tissue fat-derived fillers, tissue-based medical devices, etc. and build a Regenerative Healthcare Platform that encompasses the next generation bio sector by providing new business expansion and differentiation solutions.
