Tissue engineering for regenerative medecine is a growing field which faces structural and functional challenges at different scales. Real-time quantitative 3D characterization of tissues both in vitro and in vivo would help biologists assessing their methods. Magnetic Resonance Imaging (MRI) offers the possibility to perform such characterization non-invasively. We propose here a 7T MRI coil integrated within a perfusion tissue engineering bioreactor to perform tissue assessments throughout its growth. The MRI bioreactor is built using 3D printing and plastronics. This works resulted in a successful observation of a bioprinted tissue with a 75 µm in plane resolution.
