Mice exposed to CID or vehicle at 2, 4, 6, and 8 days after injection of AdBMP2-AdiRFP transduced hMSCs-iCasp9 cells during the formation of heterotopic bone formation. (A) Far-red fluorescence expression in the mice. (B) Quantification of far-red fluorescence in the mice. (C) Representative three-dimensional reconstructions of the microCT data collected from imaging the mice. (D) Quantification of bone volume in the mice. All data are reported as the mean ± standard error of the mean for n = 3. * Represents significant difference between groups (P <0.05).
