Trimethylation on histone H3 lysine 27 (H3K27me3) by Polycomb repressive complex 2 (PRC2) regulates the balance between self-renewal and differentiation of embryonic stem cells (ESCs). The mechanisms controlling the activity and recruitment of PRC2 are largely unknown. Here we demonstrate that the founding member of the Jumonji family, JMJ (JUMONJI or JARID2), is associated with PRC2, colocalizes with PRC2 and H3K27me3 on chromatin, and modulates PRC2 function. In vitro JMJ inhibits PRC2 methylt ...[more]

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.
