Therapeutic Benefit for Late, but Not Early, Passage Mesenchymal Stem Cells on Pain Behaviour in an Animal Model of Osteoarthritis

Figure 1

MNX surgery for induction of OA pain, or sham surgery, was performed on day 0. (a) MNX rats receiving SFM exhibited significant differences in weight-bearing asymmetry, compared to the sham-SFM rats. (b) Area under the curve (AUC) data calculated for days 31, 35, and 38 postsurgery revealed significant weight-bearing asymmetry in MNX rats at the later timepoints of the model. (c) Paw withdrawal thresholds were not significantly different in MNX rats, compared to sham controls at individual timepoints, or following AUC analysis. (d) Statistical comparison of the groups at each timepoint: two-way ANOVA with Bonferroni’s post hoc. Comparison of AUC used a Mann–Whitney’s nonparametric unpaired t-test. , MNX versus sham. Data are mean ± SEM, n = 8–10 per group.
