Figure 3. ABP immunoreactivity after secretome injection in testicular dysfunction rats treated with secretome. Reactivity of ABP was detected in the interstitial cell of the testis (red arrows). Immunoreactivity of the ABP was not detected for 1 week after the first secretome injection in the low dosage group (A) and high dosage group (B). One week after the second secretome injection, in the low dosage group (C), the immunoreactivity of ABP was strong; meanwhile, in the high dosage group (D), the immunoreactivity of ABP was moderate. One week after the third secretome injection, in the low dosage (E) and high dosage group (F), the immunoreactivity of ABP was strong. One week after the fourth secretome injection, in the high dosage group (G), the immunoreactivity of ABP was strong. There was strong reactivity of ABP in Leydig cells with 40× magnification (H).
