From: Extracellular matrix stiffness aggravates urethral stricture through Igfbp3/Smad pathway
Matrix stiffness in urethral stricture rat models increased in a time-dependent manner. (A) AFM measurement of urethral tissue matrix stiffness; (B) Statistical analysis of matrix stiffness; (C) B-mode ultrasound of the rat urethra. The white arrows indicate the loach guide wire, and the red arrows indicate the urethral stricture; (D) Stricture modeling for 2 and 4 weeks, green arrows indicate fistulas. White arrows indicate normal anterior urethra, and red arrows indicate urethral strictures, the blue circle area is difficult for physiological contrast agents to pass through; (F) Statistical analysis of E. p < 0.05 (*); p < 0.001 (***); p < 0.0001 (****), n = 3.
