Semiquantitative score of histological findings and immunoreactivity of stain. The immunoreactivity of MTS and anti-type 1 collagen antibody stain and proportion of BrdU-, PCNA-, VEGF-, and PECAM-1-positive cells were scored as detailed in Materials and Methods. ∗P < 0.05 one-way ANOVA, Tukey's post hoc test among groups. SAL (group 1, normal saline 0.2 mL); PDRN (group 2, PDRN 0.2 mL); MSC (group 3, MSC 0.2 mL); and MSC+PDRN (group 4, MSC 0.2 mL with PDRN 0.2 mL). MSC: human umbilical cord blood-derived mesenchymal stem cell; PDRN: polydeoxyribonucleotide; VEGF: vascular endothelial growth factor; PECAM: platelet endothelial cell adhesion molecule.
