Abstract: Sertoli cells are principal components of testicular seminiferous tubule epithelium. Retinol and its derivatives also play a critical role in the regulation of testicular development and spermatogenesis through sertoli cell mediation. To explore the effect of retinol on the in vitro biological characteristics of testicular sertoli cells, sertoli cells from 3 to 5 week-old porcine testis were selected as materials. Cellular viability, the expression of proliferation-related and apoptosis-related genes and secretion of cytokines were assessed. The results showed that compared with the control group, when the concentration of retinol was 5.000 and 0.125 μmol·L-1, significant effects were seen on sertoli cell viability after 24 h and 72 h (P<0.05). Adding 1.250 μmol·L-1 retinol group compared with the control group, the proliferation-related genes PCNA, BCL-2 and C-MYC were significantly down-regulated (P<0.05), apoptosis-related genes BAX was significantly up-regulated (P<0.05),and support intracellular GDNF, CSF-1 and EGF were significantly reduced in gene expression and protein levels (P<0.05). In summary, the addition of retinol can inhibit the activity of supporting cells and promote apoptosis in vitro culture conditions.
