The peritubular myoid cells (PMC) have been postulated for some time to have a role in regulation of sertoli cell activity, but knowledge of PMC cell control and function remains extremely meager, particularly in the fetus.
The SSC isolated from seminiferous tubules is often contaminated by differentiating spermatogonial cells, sertoli cells and peritubular myoid cells. Most SSC culture systems are known to contain a mixture of testicular cells with about 1.33% SSC (Aponte et al., 2005).

In addition, the AR is testosterone hormone receptor expressed in Sertoli cells, peritubular myoid cells, and Leydig cells of testis and in epithelial and stromal cells of the epididymis (Anthony et al., 1989; Zhu et al., 2000).
Several cell types were essential for spermatogenesis in the testis: germ cells, Sertoli cells, peritubular myoid cells, and ALCs [30].
The purity of isolated interstitial, Sertoli and germ cells was evaluated by performing RT-PCR using several putative marker genes, which included cholesterol side-chain cleavage enzyme and 17a-hydroxylase (interstitial cells), follicle stimulating hormone receptor and Pern homeobox gene (Sertoli cells), alkaline phosphatase and fibronectin (myoid cells) and protamine 2 and stimulated by retinoic acid gene 8 homolog (germ cells) (32, 33).
For the first time, Dirami et al performed differential plating to enrich porcine Type A Spermatogonia to decrease Sertoli and myoid cells (10).
