The objective of this study was to investigate the effect of different biomaterials on bone healing in vivo in a mouse model of bone injury. These materials; matrigel, purecol gel and hydroxyapatite (HA) are potential matrices to support stem cells. Optimized in vivo MR microscopy and micro computed tomography were used to assess fracture repair. In addition, MRI images and CT scans were compared at the same time point, to show the difference between them in revealing the actual stage of healing.
