Induction of the Germ-Cell Fate from Pluripotent Stem Cells in Cynomolgus Monkeys [bulk RNA-Seq]

ABSTRACT: In vitro reconstitution of germ-cell development from pluripotent stem cells (PSCs) has created key opportunities to explore the fundamental mechanisms underlying germ-cell development, particularly in mice and humans. Importantly, such investigations have clarified critical species differences in the mechanisms regulating mouse and human germ-cell development, highlighting the necessity of establishing an in vitro germ-cell development system in other mammals, such as non-human primates. Here, we show that multiple lines of embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) in cynomolgus monkeys (Macaca fascicularis; cy) can be maintained stably in an undifferentiated state under a defined condition with an inhibitor for WNT signaling, and such PSCs are induced efficiently into primordial germ cell-like cells (PGCLCs) bearing a transcriptome similar to early cyPGCs. Interestingly, the induction kinetics of cyPGCLCs from cyPSCs is faster than that of human (h) PGCLCs from hPSCs, and while the transcriptome dynamics during cyPGCLC induction is relatively similar to that during hPGCLC induction, it is substantially divergent from that during mouse (m) PGCLC induction. Our findings delineate common as well as species-specific traits for PGC specification, creating a foundation for parallel investigations into the mechanism for germ-cell development in mice, monkeys and humans.

Functional primordial germ cell-like cells from pluripotent stem cells in rats

Project description: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. We show that epiblast-like cells in floating aggregates form rat PGCLCs. The gonadal somatic cells support maturation and epigenetic reprogramming of the PGCLCs. Notably, rat PGCLCs transplanted into the seminiferous tubules of germline-less rats produce spermatids, leading to the birth of viable offspring. Insights from our rat model will elucidate conserved and divergent mechanisms essential for the broad applicability of in vitro gametogenesis.

Mapping developmental paths of monkey primordial germ-like cell differentiation from pluripotent stem cells by single cell RNA sequencing analysis

Project description:The induction of the primordial germ-like cells (PGCLCs) from primate pluripotent stem cells (PSCs)provides a powerful system to study the cellular and molecular mechanism underlying germline specification, which are difficult to study in vivo. However a comprehensive single cell RNA sequencing(scRNA-seq) analysis of the developmental trajectory of PGCLCs differentiation that also dissects the required niche has not been achieved. Here, we applied the embryoid body (EB) differentiation system to induce PGCLCs specification from male and female monkey naïve-state PSCs and then performed high throughput scRNA-seq analysis of approximately 40000 of naïve cells and cells within EBs. We found that EBs provided a niche for PGCLCs differentiation by secreting growth factors critical for PGCLCs specification, such as BPM2, BMP4 and WNT3. Moreover, the developmental trajectory of PGCLCs was reconstituted and gene expression dynamics were revealed. Our study outlines the roadmap of PGCLCs specification from PSCs and provides insights that will improve the differentiation efficiency of PGCLCs from PSCs.

Heading towards a dead end: the role of DND1 in germ line differentiation of human iPSCs

Project description:The DND microRNA-mediated repression inhibitor 1 (DND1) is a conserved RNA binding protein (RBP) and plays an important role in survival and maintenance of primordial germ cells (PGCs) and the development of the male germline in zebrafish and mice. It was shown to be expressed in human pluripotent stem cells (PSCs), PGCs, and spermatogonia, but little is known about its specific role in pluripotency and human germline development. Here we use CRISPR/Cas mediated knockout and PGC-like cell (PGCLC) differentiation in human iPSCs to analyse if DND1 (1) plays a role in maintaining pluripotency and (2) in specification of PGCLCs. We generated several clonal lines with biallelic loss of function mutations and analysed their potential to differentiate towards PGCLCs and their gene expression on RNA and protein level via bulk RNA sequencing and mass spectrometry. The generated knockout iPSCs showed no differences in pluripotency gene expression, proliferation nor trilineage differentiation potential, but yielded reduced numbers o PGCLCs compared to their parental iPSCs. RNAseq analysis in PGCLCs showed significantly reduced expression of genes associated with cellular developmental processes and cell differentiation in knockout cells, including known markers for PGCs (NANOS3, SOX17, PRDM1, EPCAM) and naïve pluripotency (TFCP2L, DNMT3L).

Efficient generation of marmoset primordial germ cell-like cells using induced pluripotent stem cells [bulk RNA-seq]

Project description:Reconstitution of germ cell fate from pluripotent stem cells provide the opportunities to understand the molecular underpinning of germ cell development. Here, we established a several culture methods of induced pluripotent stem cells (iPSCs) in common marmoset (Callithrix jacchus, cj), which stably propagate in an undifferentiated state. Notably, iPSCs cultured on feeder layer in the presence of a WNT signaling inhibitor upregulate genes related to ubiquitin-dependent protein catabolic process and acquire permissive state that readily differentiate into primordial germ cell-like cells (PGCLCs) bearing immunophenotypic and transcriptomic similarities to pre-migratory cjPGCs. Induction of cjPGCLCs accompanies transient upregulation of mesodermal genes and culminate in establishing primate-specific transcriptional network similar to humans and cynomolgus monkeys. Moreover, cjPGCLCs can be expanded in monolayer while retaining cellular state. Upon co-culture with mouse testicular somatic cells, these cells acquire DDX4+ early prospermatogonia-like state. Our findings provide a framework for understanding and reconstituting germ cell development in marmoset in vitro, which serve as an comparative tool and foundation for a preclinical model for human in vitro gametogenesis.

Induction of primordial germ cell-like cells from common marmoset embryonic stem cells by inhibition of WNT and retinoic acid signaling

Project description:Reconstitution of germ cell lineage using pluripotent stem cells provides a unique platform to deepen our understanding of the mechanisms underlying germ cell development and to produce functional gametes for reproduction. Here, we report a robust induction of primordial germ cell-like cells (PGCLCs) from common marmoset (Callithrix jacchus) embryonic stem cells. The robust induction was achieved by not only activation of the conserved PGC-inducing signals, WNT and BMP4, but also temporal inhibitions of WNT and retinoic acid signals, which prevent mesodermal and neural differentiation, respectively, during PGCLC differentiation. Many of the gene expression and differentiation properties of common marmoset PGCLCs were similar to those of human PGCLCs, making this culture system a reliable and useful primate model. Finally, we identified PDPN and KIT as surface marker proteins by which PGCLCs can be isolated from embryonic stem cells without genetic manipulation. This study will expand the opportunities for research on germ cell development and production of functional gametes to the common marmoset.

Association between Activated Loci of HML-2 Primate-Specific Endogenous Retrovirus and Newly Formed Chromatin Contacts in Human Primordial Germ Cell-like Cells

Project description:The pluripotent stem cell (PSC)-derived human primordial germ cell-like cells (PGCLCs) are a cell culture-derived surrogate model of embryonic primordial germ cells. Upon differentiation of PSCs to PGCLCs, multiple loci of HML-2, the hominoid-specific human endogenous retrovirus (HERV), are strongly activated, which is necessary for PSC differentiation to PGCLCs. In PSCs, strongly ac-tivated loci of HERV-H family HERVs create chromatin contacts, which are required for the plu-ripotency. Chromatin contacts in the genome of human PSCs and PGCLCs were determined by Hi-C sequencing, and their locations were compared with those of HML-2 loci strongly activated in PGCLCs but silenced in the precursor naïve iPSCs. In both iPSCs and PGCLCs, the size of chromatin contacts were found to be around one megabase, which corresponds to the Topologically Associ-ated Domains in the human genome but is slightly larger in PGCLCs than iPSCs. The number of small-sized chromatin contacts diminished while numbers of larger-sized contacts increased. The distances between chromatin contacts newly formed in PGCLCs and the degrees of activation of the closest HML-2 loci showed significant inverse correlation. Our study provides evidence that strong activation of HML-2 provirus loci may be associated with newly formed chromatin contacts in their vicinity, potentially contributing to PSC differentiation to the germ cell lineage.
