Micro-CT images.

<p>(A) Micro-CT images of calvarial bone during regeneration over study period. Progressive wound healing is observed, and continuity of newly formed bone network at GGTDBT and GGT-treated sites is comparable to that of host bone in weeks 4 and 8. (HB = host bone, NB = new bone, and area in <i>circular margin</i> indicates original margin of calvarial bone defect. (B) Percentage area repair rate in defects, as measured by micro-CT at 4 and 8 weeks. Amount of regenerated bone increased over study period. * <i>p</i> < 0.05, **<i>p</i> < 0.01.
