Radiography observation in bone defect model.

<p><b>A)</b> X-rays photograph of rat radical defects in different groups at 2 weeks, 4 weeks, and 12 weeks showing complete bridging of the defect in group 3, however, a radiolucent line was still present at the defect site in group 1 at 12 weeks. <b>B)</b> Radiographical scoring also showed that new bone formation in group 3 was more significant difference than the other groups at 12 weeks (p<0.05). (Group 1 referred to <i>β</i>-TCP group; Group 2 referred to ADSCs/<i>β</i>-TC group; Group 3 referred to Ad-CGRP-ADSCs/<i>β</i>-TCP group).
