Advances in Controlled Oxygen Generating Biomaterials for Tissue Engineering and Regenerative Therapy
2019
Oxygen (O2) generating biomaterials are emerging as important compositions to improve our capabilities in supporting tissue engineering and regenerative therapeutics. Several in vitro studies demonstrated the usefulness of O2 releasing biomaterials in enhancing cell survival and differentiation. However, more efforts are needed to develop materials that can provide sustained O2 release for the long-term. In this paper, we present different O2 generating sources, including hydrogen peroxide, sodium percarbonate, calcium peroxide and magnesium peroxide, and also cover types of carriers and relevant methods of fabricating O2 generating systems. Then, the applications of O2 generating materials in supporting engineered constructs, supplying high O2 demanding cell transplants, and supporting ischemic tissues are discussed. Moreover, the challenges and future perspectives are highlighted.
