Different Effects of Implanting Sensory Nerve or Blood Vessel on the Vascularization, Neurotization, and Osteogenesis of Tissue-Engineered Bone In Vivo

Figure 6

Staining of NPY at 4, 8, and 12 weeks after implantation. NPY staining showed that there was more intensive NPY in groups SN and VB than in group Blank at different times, and the NPY staining was mainly localized to the periphery of the newly generated bone tissues and the blood vessels (black arrows) (×400, scale bar represents 100 μm).
