The expression of relevant miRNAs in testicular cells. A large number of miRNAs are responsible for the normal function of reproductive organ and spermatogenesis. They control all levels of spermatogenesis including 1-Leydig and Sertoli cells development, 2-spermatogonial stem cells formation and their differentiation to 3-spermatogonia, 4-primary spermatocytes, 5-secondary spermatocytes, 6-round spermatids, and 7-mature sperm cells. Data from Harchegani et al.53

Abbreviations: SSCs indicates spermatogonial stem cells; SPG, spermatogonia; PSPC, primary spermatocytes; SSPC, secondary spermatocytes; RS, round spermatids; SPs, sperm cells; SCs, sertoli cells; miRNAs, microRNAs.
