3D bioprinted scaffolds are one of the most novel and promising tissue regenerative therapeutics currently in development (e.g. to repair damaged cardiac tissue). Validation of correct scaffold placement and retention post-implantation is essential, but it is challenging to visualize scaffolds in-vivo given their similar material properties to native tissue. In this study, a T1-reducing contrast agent, MnPNH2, was utilized to create an MR-trackable, bioprinted scaffold. In-vitro and in-vivo results confirmed the novel scaffold provided an environment conducive to cell growth and offered significant bright contrast for post-implantation scaffold monitoring in rats.
