Changes in gene expression of EMT-related genes in Achilles tendon following surgical tear and repair. Target genes were normalized to B2M expression, and further normalized to the control group. Differences were tested using a one-way ANOVA (α=0.05) followed by Tukey’s post-hoc sorting. a, different from Control; b, different from 3D; c, different from 7D; d, different from 14D. N=6 tendons per group.
