Impact Statement:
This study represents significant advancement in the use of biomimetic scaffolds to direct zonal osteochondral tissue formation. We describe the use of a novel fluorescent reporter system that enables the real-time evaluation of cellular differentiation in a nondestructive manner. In this study, we use this tool to confirm the osteogenic and chondrogenic capabilities of our scaffold alongside control scaffolds, and use cryohistological methods to probe zone-specific differences in cell and tissue quality. We believe this approach can be widely adopted by others for a variety of biomaterial and cell systems in the development of tissue engineered therapeutics.
