Project description:The molecular mechanisms underlying the commitment of cells to the germ cell lineage and the subsequent formation of germ cells during mammalian development remain poorly understood due to an inability to obtain sufficient amounts of cellular materials to conduct thorough in-vitro analyses. Although primordial germ cells (PGCs) have been generated and isolated from embryonic stem cells (ESCs) in vitro, concurrent expression of several cell surface receptors and transcription factors, at various levels, confounds the identification of these cells. To date, only a few genes that mark the onset of germ cell commitment to the epiblast, including tissue nonspecific alkaline phosphatase (TNAP), Blimp1, Stella, and Fragilis, have been used with some degree of success to detect PGC formation in in-vitro model systems. In light of the current literature, the generation of an unlimited supply of germ cells and gametes from pluripotent stem cells would greatly facilitate studies into reproductive development. To accomplish this, we would need to discover novel markers that are specifically expressed in germ cells. Here we identified four genes that are specifically expressed in male and female germ cells, both in vivo and in vitro, but are not expressed in somatic tissues or ESCs. Expression of these genes therefore allows us to distinguish committed germ cells from undifferentiated pluripotent cell populations, a prerequisite for the successful derivation of germ cells and gametes in vitro. For RNA isolation, PGCs were sorted by FACS, collected by centrifugation, lysed in RLT buffer (QIAGEN), and processed using RNeasy Micro kits with on-column DNase digestion as per the manufacturer's instructions. Integrity of RNA samples was quality-checked using a 2100 Bioanalyzer (Agilent). If possible, 300 ng of total RNA per sample was used as starting material for linear amplification (Illumina TotalPrep RNA amplification kit, Ambion), which involved synthesis of T7-linked double-stranded cDNA and 14 hrs of in-vitro transcription incorporating biotin-labeled nucleotides. Purified and labeled cRNA was then quality-checked on a 2100 Bioanalyser, and hybridized as biological or technical duplicates for 18 hrs onto MouseRef-8 v2 gene expression BeadChips (Illumina), following the manufacturer's instructions. After being washed, the chips were stained with streptavidin-Cy3 (GE Healthcare) and scanned using the iScan reader and accompanying software. 44 samples were analyzed.

Project description: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). The global transcription profiles, epigenetic reprogramming, and cellular dynamics during PGCLC induction from EpiLCs are a meticulous capture of those associated with PGC specification from the epiblasts. Furthermore, we identify Integrin-beta 3 and SSEA1 as markers that purify PGCLCs with spermatogenic capacity free from tumorigenic undifferentiated cells. With the reconstitution of PGC specification pathway from the naive inner cell mass state, our study defines a paradigm for the essential step of in vitro gametogenesis. We performed this analysis to reveal the characters of the cells that we created in this study, epiblast-like cells (EpiLCs) and primordial germ cells-like cells (PGCLCs). Because EpiLCs were induced from embryonic stem cells (ESCs), and equivalent to pre-gastrulating epiblast (embryonic day [E] 5.5-6.0) in vivo (embryo), ESCs and epiblast were included in this analysis. Epiblast stem cells (EpiSCs) are a culture cell type derived from epiblast, and were also included. PGCLCs were supposed to be equivalent to E9.5 PGCs based on reporter fluorescent transgene expressions and epigenetic properties, and therefore E9.5 PGCs were also inckuded in this analysis. Because epiblast and E9.5 PGCs are of a small number of cells in embryos (a few hundred to thousand cells), cDNAs were amplified with a quantitative global PCR method (Kurimoto et al., 2006, Nucleic Acids Research) for microarray analyses. We took two biological replicate for each cell type.
