Fluorescence molecular tomography (FMT) is a novel tomographic near-infrared (NIR) imaging modality that enables 3D quantitative determination of fluorochrome distribution in tissues of live small animals at any depth. This study demonstrates a noninvasive, quantitative method of monitoring engineered bone remodeling via FMT. Murine mesenchymal stem cells overexpressing the osteogenic gene BMP2 (mMSCs-BMP2) were implanted into the thigh muscle and into a radial nonunion bone defect model in C3H/HeN mice. Real-time imaging of bone formation was performed following systemic administration of the fluorescent bisphosphonate imaging agent OsteoSense, an hydroxyapatite-directed bone-imaging probe. The mice underwent imaging on days 7, 14, and 21 postimplantation. New bone formation at the implantation sites was quantified using micro-computed tomography (micro-CT) imaging. A higher fluorescent signal occurred at the site of the mMSC-BMP2 implants than that found in controls. Micro-CT imaging revealed a mass of mature bone formed in the implantation sites on day 21, a finding also confirmed by histology. These findings highlight the effectiveness of FMT as a functional platform for molecular imaging in the field of bone regeneration and tissue engineering.
