“…According to the data deduced from this study, the gene expression of Sycp3 significantly increased in RA + E group compared to the control group and E group respectively ( p < .01). Dong et al () found that this gene expression remarkably increased at later time points. They demonstrated that RA combined with SSC conditions considerably increased the efficiency of mouse ESCs differentiation by enhancing spermatogenic genes expression (Dong et al, ).…”

“…It should be noted that the successful stimulation of Stra8 in this study was observed by adding RA (Li et al, ). Results of real‐time PCR in Dong et al () study revealed a considerable increase of Stra8 expression in spermatogonial stem cells (SSC) conditions with RA on day 3. Decreased expression of Stra8 expression in SSC conditions with RA was also observed on day 5.…”

“…Decreased expression of Stra8 expression in SSC conditions with RA was also observed on day 5. Dong et al found that the common impacts of SSC and RA conditions could enhance the expression of Stra8 for facilitating the differentiation initiation (Dong et al, ). In addition, Silva et al () determined that Stra8 expression in the treated cells with RA for 7 days experienced a significant increase compared to day 7 of untreated control cultures, which is inconsistent with our observations, because these studies worked on mESCs cultures treated with RA and testosterone (Silva et al, ).…”

“…One of the derivatives of vitamin A is retinoic acid (RA), which has significant roles in cellular differentiation and embryogenesis and modulates meiotic initiation in mice (Dong et al, ; Zhu et al, ). Interestingly, RA could also improve spermatogenesis and induce downstream gene expression in male testes after birth (Bowles & Koopman, ) via activating major genes that begin meiosis (Rhinn & Dolle, ).…”

This research aimed to explore the impacts of retinoic acid (RA)/17β-estradiol (E) induction and embryoid body formation to enhance differentiation of mouse-induced pluripotent stem cells (miPSCs) into male germ cells in vitro. Flow cytometry and qPCR were conducted to describe miPSCs differentiation process. Various temporal expression profiles of germ cell-related genes were traced. Stra8 gene expression increased in the RA group on the 4th day compared to other groups. The RA group experienced a more significant increase than E group. The expression of Sycp3 increased in RA + E group on 4th day compared with other groups. Expression of AKAP3 enhanced in the RA + E group than other groups on day 4. Moreover, miPSCs showed that this gene expression in the RA + E group was increased in comparison to RA and E groups on day 7. AKAP3 gene expression on day 7 of miPSCs decreased in RA and E groups. Flow cytometry data indicated that 3%-8% of the cells in sub-G1 stage were haploid after RA and E induction compared to other groups on day 4. This study showed that miPSCs possess the power for differentiating into male germ cells in vitro via formation of embryoid body by RA with/or E induction.

Numerous reagents were employed for differentiating induced pluripotent stem cells (iPSCs) into male germ cells; however, the induction procedure was ineffective. The aim of this study was to improve the in vitro differentiation of mice iPSCs (miPSCs) into male germ cells with retinoic acid (RA) and progesterone (P). miPSCs were differentiated to embryoid bodies (EBs) in suspension with RA with or without progesterone for 0, 4, and 7 days. Then, the expression of certain genes at different stages of male germ cell development including Ddx4 (pre meiosis), Stra8 (meiosis), AKAP3 (post meiosis), and Mvh protein was examined in RNA and/or protein levels by real-time polymerase chain reaction or flow cytometry, respectively. The Stra8 gene expression increased in the RA groups on all days. But, expression of this gene declined in RA + P groups. In addition, an increased expression of Ddx4 gene was observed on day 0 in the P group. Also, a significant upregulation was observed in the expression of AKAP3 gene in the RA + P group on days 0 and 4. However, gene expression decreased in P and RA groups on day 7. The expression of Mvh protein significantly increased in the RA group on day 7. The Mvh expression was also enhanced in the P group on day 4, but it decreased on day 7, while this protein upregulated on day 0 and 7 in the RA + P group. The miPSCs have the capacity for in vitro differentiation into male germ cells by RA and/or progesterone. However, the effects of these inducers depend on the type of combination and an effective time.

Previous studies have shown that primordial germ cell‐like cells (PGCLCs) can be obtained from human, porcine and mouse skin‐derived stem cells (SDSCs). In this paper, we found retinoic acid (RA), the active derivative of vitamin A, accelerated the growth of porcine primordial germ cells (pPGCs) and porcine PGCLCs (pPGCLCs) which were derived from porcine SDSCs (pSDSCs). Moreover, flow cytometry results revealed that the proliferation promoting effect of RA was attenuated by U0126, a specific inhibitor of extracellular signal‐regulated kinase (ERK). Western blot analysis showed the protein level of ERK, phosphorylated ERK, cyclin D1 (CCND1), and cyclin‐dependent kinase 2 (CDK2) increased after stimulation with RA, and this effect could also be abolished by U0126. Our data revealed that ablation of ERK expression by U0126 should significantly decrease proliferation of pPGCLCS. This reduction was because CCND1 and CDK2 proteins level decrease and subsequently the pPGCLCs were arrested in the G0/G1 phase. In addition, we also confirmed RA indeed promoted the proliferation of pPGCs isolated from porcine fetal genital ridges in vitro. Furthermore, our data indicated that DNA methylation pattern were changed in pPGCLCs and this pattern were more similar to pPGCs.
