Figure 3. Comparison of granulation tissue-specific protein expression. A: VEGF levels, B: SDF-1α levels, and C: CXCR4 levels. *** indicates p<0.001 when compared to levels before treatment; ### indicates p<0.001 when compared to the control group. VEGF, vascular endothelial growth factor; SDF-1a, stromal cell-derived factor-1α; CXCR4, chemokine receptor 4.
