Antioxidant Properties of Tonsil-Derived Mesenchymal Stem Cells on Human Vocal Fold Fibroblast Exposed to Oxidative Stress

<div>Matrix metalloproteinase (MMP) activity assay. (a–d) Treatment with tBHP slightly suppressed the activity of MMP 1 and strongly inhibited those of MMPs 8, 2, and 9. The activities of all MMPs were significantly restored after coculturing with TMSCs. Results are 3 technical replicates of TMSC from one donor. Representative results from two different TMSCs with similar tendency were presented. For multigroup comparison, ANOVA followed by the Bonferroni post hoc test was used for statistics. Results are shown as the <span class="nowrap"><svg height="9.10327pt" id="M59" style="vertical-align:-0.3499298pt" version="1.1" viewbox="-0.0498162 -8.75334 58.1969 9.10327" width="58.1969pt"
