Figure 5: Effect of pM2b on matrix metalloproteinase contents in the healing tissue. (A) Protein measurements in MMP extracts of tissue samples from the wounds topically treated with pM2b (50 μl, 230 nM) or saline, measured by Bradford assay. (B) MMP activity in gelatin zymography. Mean ± SEM, n=8, bp<0.01 vs control.
