Abstract:
Objective To evaluate the expressive levels of calcitonin gene related peptide (CGRP) and neuropeptide Y (NPY) in tissue-engineered bone with fascia flap in vivo. Method A segmental bone defect 1.5cm in length was made at the both radius of 12 healthy New Zealand rabbits. The defects were repaired by implantation in two ways: for left radius, engineered bone with fascia flap was implanted (served as experiment group), and for right radius only engineered bone was implanted (served as control group). 3, 6 and 12 months after implantation, the expressions of CGRP and NPY in the new bone were determined with immunohistochemistry and semi-quantified using image analysis software. Results CGRP and NPY expressions in the both groups were significantly increased in a time-dependent manner (P
