Testicular tissues from adult males of the species Artibeus lituratus, Artibeus planirostris, Uroderma bilobatum, and Vampyrodes caraccioli from the eastern Amazonia were analyzed by optical/electron microscopy and immunofluorescence of meiotic proteins involved in synapsis (SYCP3 and SYCE3), sister-chromatid cohesion (SMC3), and chromatin silencing (BRCA1, γ-H2AX, and RNApol 2).
Cumulus cell-conditioned medium supports embryonic stem cell differentiation to germ cell-like cells.

Quantitative polymerase chain reaction analysis revealed that 20%-40% CCM induced the highest expression of primordial germ cell-specific (deleted in Azoospermia- like (Dazl), dead (Asp-Glu-Ala-Asp) box polypeptide 4 (Vasa also known as DDX4) and promyelocytic leukemia zinc finger protein (Plzf)); meiotic (synaptonemal complex protein 3 (Sycp3), mutl homolog I (Mlh1), transition protein 1/2 (Tnp1/2) and protamine 2 (Prm2); spermatocyte-specific boule-like RNA binding protein (Boule) and tektin 1 (Tekt1)) and oocyte-specific growth differentiation factor 9 (Gdf9) and zona pellucida 2 /3 (Zp2/3)) genes over 8-14 days in culture.
Connecting cis-elements and trans-factors with mechanisms of developmental regulation of mRNA translation in meiotic and haploid mammalian spermatogenic cells.
Boston, United States. In Reproduction, 2013
As a result, the mechanisms involving well-studied mRNAs (Ddx4/Mvh, Prm1, Prm2, and Sycp3) and factors (DICER1, CPEB1, DAZL, DDX4/MVH, DDX25/GRTH, translin, and ELAV1/HuR) are incompletely understood.

However, due to numerous factors involved, positive results obtained by the "candidate gene approach" remain limited (for example, SCP3 and CREM).
