a Dental pulp stem cell-conditioned media (DPSC-CM) promoted neurite outgrowth of DRG neurons. DRG neurons (stained with neurofilament heavy-chain immunofluorescence) extended neurites, and the extensions were significantly promoted in the presence of DPSC-CM compared with that in the absence of DPSC-CM. Scale bars = 100 μm. The total length (b) and joint number (c) of neurite outgrowths in DRG neurons were calculated using a computed image analysis system (Angiogenesis Image Analyzer Ver. 2, KURABO Industries, Osaka, Japan). The results are means ± SEM. **P < 0.01, vs. control group
