Figure 2From: High glucose concentration up-regulates the expression of matrix metalloproteinase-9 and -13 in tendon cells Real-time PCR assay to assess the effect of a high glucose concentration on the mRNA expression of MMP-2, MMP 8, MMP-9, and MMP-13 (* p < 0.05 by Kruskal-Wallis test, n = 3; X-axis, glucose concentration; Y-axis, relative fold change).
