Abstract
Tissue engineering has the potential to revolutionize treatments for patients suffering from critical-sized craniofacial bone defects, but it has yet to make a substantial impact in clinical practice. One of the barriers to improving the design of tissue-engineered bone grafts (TEBGs) is the lack of adequate techniques to study how transplanted cells, host cells, and biomaterials interact to facilitate the dynamic healing process. In this perspective, we discuss recent advances in quantitative imaging that may be adapted to provide high spatiotemporal resolution of the 3D tissue microenvironment during cranial bone regeneration. The adoption and application of these imaging technologies will provide a more rigorous framework for evaluating TEBG performance and enable the development of next-generation TEBGs for craniofacial repair.
