Immunohistochemical analysis of neo-vascularization (A) Mature blood vessels of different diameters were observed via α-SMA staining at day 14. Images were taken under 4X and 10× magnifications (B) The quantification of blood vessels demonstrated significant increase in the treatment groups with highest number in the Q + hUC-MSC group. For statistical analysis, one-way ANOVA with Bonferroni post-hoc test was performed. Data is represented as mean ± S.E.M (n = 3); p-value ≤ 0.05 was considered statistically significant (where ∗∗∗ = p < 0.001, ∗ = p < 0.05).
