As shown in the results comparing the healthy and tendinopathy samples, the relative mRNA expressions of COL3A1, COX2, SCX, MMP1, and ACTA2 were increased by 1.4, 1.8, 2.7, 1.3, and 1.6 times in the SP-treated samples compared to the PBS-controls (p < 0.05 in all), respectively. The gene discussed is MMP1; the disease is disease of the tendon.
