From: Relaxin inhibits patellar tendon healing in rats: a histological and biochemical evaluation
Relaxin disrupts the balance between MMPs and TIMP. a: Immunohistochemical staining of TIMP1, MMP1, MMP9, and MMP13 in the tendon wound areas in the 2nd and 4th postoperative weeks. (Scale bar = 200 μm). b: Relative expression of MMP1, MMP9, MMP13 and TIMP1 in tendon wound areas. MMP9 and MMP13 shows a significant difference in the 2nd and 4th postoperative weeks. *p < 0.001 compared with vehicle group
