(Submitter supplied) To investigate the interplay of X-chromosome status and meiosis during primordial germ cell (PGC) maturation, we differentiated mouse embryonic stem cells (ESCs) via epiblast-like cells (EpiLCs) into primordial germ cell like cells (PGCLCs) and further into meiotic germ cells. During the differentiation of PGCLCs, we assessed the kinetics of X-chromosome inactivation and reactivation. We generated allele-specific total RNA-seq datasets to assess gene inactivation and reactivation dynamics, as well as allele-specific single-cell RNA-seq using SMART-Seq v5 to investigate the interplay of meiosis and X-chromosome status in germ cells.

(Submitter supplied) Human in vitro oogenesis provides a framework for clarifying the mechanism of human oogenesis. To create its benchmark, it is vital to promote in vitro oogenesis using a model physiologically close to humans. Here, we establish a foundation for in vitro oogenesis in cynomolgus (cy) monkeys (Macaca fascicularis): cy female embryonic stem cells harboring one active and one inactive X chromosome (Xa and Xi, respectively) differentiate robustly into primordial germ cell-like cells, which in xenogeneic reconstituted ovaries develop efficiently into oogonia and, remarkably, further into meiotic oocytes at the zygotene stage. more...

(Submitter supplied) The generation of properly functioning gametes in vitro, a key goal in developmental/reproductive biology, requires multi-step reconstitutions of complex germ cell development. Based on the logic of primordial germ cell (PGC)-specification, we demonstrate here the generation of PGC-like cells (PGCLCs) in mice with robust capacity for spermatogenesis from embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) through epiblast-like cells (EpiLCs), a cellular state highly similar to pre-gastrulating epiblasts, but distinct from epiblast stem cells (EpiSCs). more...

(Submitter supplied) In vitro generation of germ cells from pluripotent stem cells (PSCs) can crucially impact future reproductive medicine and animal breeding. A decade ago, in vitro gametogenesis was established in the mouse. However, induction of primordial germ cell-like cells (PGCLCs) to produce fertile gametes has not been achieved in any other species. Here, we demonstrate the induction of functional PGCLCs from rat PSCs. more...

(Submitter supplied) The expansion of primordial germ cells (PGCs), the precursors for the oocytes and spermatozoa, is a key challenge in reproductive biology/medicine. Using a chemical screening exploiting PGC‐like cells (PGCLCs) induced from mouse embryonic stem cells (ESCs), we here identify key signaling pathways critical for PGCLC proliferation. We show that the combinatorial application of Forskolin and Rolipram, which stimulate cAMP signaling via different mechanisms, expands PGCLCs up to ~50‐fold in culture. more...

(Submitter supplied) Comparison of gene expression differences between Dnmt3L heterozygous and wildtype pachytene spermatocytes, and similarly between Dnmt3L heterozygous and wildtype round spermatids which were isolated from the Dnmt3L knockout mouse line. This array was conducted to address the hypothesis that Dnmt3L heterozygosity results in deregulated gene expression within spermatocytes and spermatids. Results show that Dnmt3L heterozygosity causes numerous genes to be differentially regulated on a genome-wide level, showing that DNMT3L has an important role in regulating gene expression within these male germ cells.

(Submitter supplied) In contrast to mouse, human female germ cells develop asynchronously. Germ cells transition to meiosis, erase genomic imprints, and reactivate the X chromosome. It is unknown if these events all appear asynchronously, and how they relate to each other. Here we combine exome sequencing of human fetal and maternal tissues with single-cell RNA-sequencing of five donors. We reconstruct full parental haplotypes and quantify changes in parental allele specific expression, genome-wide. more...

(Submitter supplied) Mammalian oogenesis is an intricate and coordinated process involving dramatic changes in the transcriptional architecture. Through the small number of cells RNA sequencing (RNA Seq), we comprehensively uncovered the transcriptome dynamics of the mouse PGCs, FGSCs, GV Oocytes and M II Oocytes using. These results would provide some valuable navigation for the mechanism research of mammalian FGSCs in the future.

(Submitter supplied) During spermatogenesis, germ cells that fail to synapse their chromosomes or fail to undergo meiotic sex chromosome inactivation (MSCI) are eliminated via apoptosis during mid-pachytene. Previous work showed that Y-linked genes Zfy1 and Zfy2 act as “executioners” for this checkpoint, and that wrongful expression of either gene during pachytene triggers germ cell death. Here, we show that in mice, Zfy genes are also necessary for efficient MSCI and the sex chromosomes are not correctly silenced in Zfy-deficient spermatocytes. more...

(Submitter supplied) MAX (MYC Associated Factor X) is generally known as a mandatory partner for MYC transcription factor, which activates various genes involved in cell growth and metabolism. On the other hand, MAX, when interacting with MGA, forms the polycomb repressive complex (PRC) 1.6, one of the subtypes of PRC1, which directs the transcriptionally repressed chromatin state. Although physiological significance is not known at present, we have previously demonstrated that mouse embryonic stem cells (ESCs) bear a potential to onset meiosis, albeit not germ cells, and PRC1.6 prevent ESCs from their ectopic onset of meiosis (Suzuki et al., 2016, Nat. more...

(Submitter supplied) Expression profiling of isolated populations of prepachytene spermatocytes, pachytene spermatocytes and spermatids of males carrying a translocation T(16;17)43H was performed to study the influence of this translocation on gene expression from individual chromosomes. To evaluate the transcriptional behavior of individual chromosomes in the sterile B10-T43/+ males and their fertile congenic B10-T43/T43 and B10 counterparts, we compared their transcriptomes in sorted populations of pre-pachytene primary spermatocytes, pachytene primary spermatocytes and spermatids. more...

(Submitter supplied) Erasure of epigenetic memory is required to convert somatic cells towards pluripotency. Reactivation of the inactive X chromosome (Xi) has been used to model epigenetic reprogramming in mouse, but human studies are hampered by Xi epigenetic instability and difficulties in tracking partially reprogrammed iPSCs. Here we used cell fusion to examine the earliest events in the reprogramming-induced Xi reactivation of human female fibroblasts. more...
