MicroRNAs (miRNAs) have been widely identified in porcine testicular tissues and implicated as crucial regulators of proliferation, apoptosis, and differentiation in porcine spermatogenesis related cells. However, the function roles of most of the miRNAs that have been identified in Sertoli cells are poorly understood. In the present study, six experiments were conducted to study the regulatory role of miR-10b in porcine immature Sertoli cells. In experiment 1, the results showed that the relative mRNA expression level of miR-10b in porcine tes...
