From: Platelet-rich plasma (PRP) accelerates murine patellar tendon healing through enhancement of angiogenesis and collagen synthesis

Fig. 6

Time-dependent change in the FT ratio of the PRP and control group. FT ratio: the ratio of collagen fibers stained with Azan to the entire tendon tissue. FT ratio was measured using the KS400 image analyzing software (Carl Zeiss, Oberkochen, Germany). The percentages of collagen fiber area positively stained with Azan in the region of interest (ROI) manually drawn along the tendon periphery were determined by computer-assisted morphometry, with a high percentage indicating better tendon structure containing rich collagen fiber as closer to normal tendon. Data are presented as mean ± SD (*p < 0.05, **p < 0.01)
