Immunohistochemical analyse of renal MMP9 and TIMP-1. a Paraffin sections of kidney from control, model and BMSC-treated groups (Control, Model and BMSC respectively) were stained with MMP9 and TIMP-1. The staining results were observed under a light microscope, original magnification × 400. b The expression of MMP9 and TIMP-1 were determined by RT-PCR. Quantitative data are provided as the mean ± SD. *p < 0.05, **p < 0.01. c The MMP9/TIMP-1 ratio was further calculated. The statistical data (n = 10) are given as the mean ± SD, **p < 0.01, *p < 0.05
