We found that EBA was strongly and consistently detected in epithelial cells of the rete testis and dorsolateral prostate gland,and in a few epithelial cells of the ventral prostate gland,the seminal vesicle and the coagulating gland.
Conclusion: the components in retetestis fluid can regulate the EGFR expression and structure of epididymal duct in initial segment and corpus through different mechanism.
