Radiographic images of Nell-1 treated spine (a) and PBS treated control group (d) 4 weeks after implantation. Micro-computerized tomography (μCT) scanning of Nell-1 (b, c) and PBS (e, f) treated spine: middle panels (b, e) show reconstructed 3D images; right panels (c, f) show coronal section images of 3D μCT. New bone formation bridging the transverse processes of L4 and L5 was observed in the Nell-1 treated spine. For the control group, there was no evidence of a bony bridge and large clefts were observed between two transverse processes (arrows). (g) Quantification of bone volume/total volume (BV/TV) between L4 and L5 transverse processes. Significant difference from control was noted; *p < 0.01.
