Haploid embryonic stem cells

ABSTRACT: Mammalian haploid embryonic stem cells (haESCs) provide new possibilities for large-scale genetic screens because they bear only one copy of each chromosome. However, haESCs are prone to spontaneous diploidization through unknown mechanisms. Here, we report that a small molecule combination could restrain mouse haESCs from diploidization by impeding exit from naïve pluripotency and by shortening the S-G2/M phases. Combined with 2i and PD166285, our chemical cocktail could maintain haESCs in the haploid state for at least five weeks without fluorescence-activated cell sorting (FACS) enrichment of haploid cells. Taken together, we established an effective chemical approach for long-term maintenance of haESCs, and highlighted that proper cell cycle progression was critical for the maintenance of haploid state.

Overexpression of Let-7a Mitigates Diploidization in Mouse Androgenetic Haploid Embryonic Stem Cells

Project description:Mouse androgenetic haploid embryonic stem cells (mAG-haESCs) can be utilized to uncover gene functions, especially those of genes with recessive effects, and to produce semicloned mice when injected into mature oocytes. However, mouse haploid cells undergo rapid diploidization during long-term culture in vitro and subsequently lose the advantages of haploidy and the factors that drive diploidization are not well understood. In this study, we compared the small RNAs (sRNAs) of mAG-haESCs, normal ESCs and mouse round spermatids by high-throughput sequencing and identified distinct sRNA profiles. Several let-7 family members and miR-290-295 cluster miRNAs were found significantly differentially transcribed. Knockdown and overexpression experiments showed that let-7a and let-7g suppress diploidization while miR-290a facilitates diploidization. Our study revealed the unique sRNA profile of mAG-haESCs and demonstrated that let-7a overexpression can mitigate diploidization in mAG-haESCs. These findings will help us to better understand mAG-haESCs and utilize them as a tool in the future.

Inhibition of Apoptosis Reduces Diploidization of Haploid Mouse Embryonic Stem Cells during the Differentiation

Project description:Phenotypes of haploid embryonic stem cells (haESCs) are dominant for recessive traits in mice. However, one major obstacle to their use is self-diploidization in daily culture. Although haESCs maintain haploidy well by deleting p53, whether they can sustain haploidy in differentiated status and the mechanism behind remain unknown. To address that, we induced p53-deficient haESCs into multiple differentiated lineages keeping a haploid status in vitro. Besides, haploid cells also remained in chimeric embryos and teratomas arising from p53-null haESCs. Transcriptome analysis revealed that apoptosis genes were down-regulated in p53-null haESCs, comparing to that in wild-type haESCs. Finally, we knocked-out p73, another apoptosis gene, and observed stabilization of haploidy in haESCs, either. These results indicated that the main mechanism of diploidization was apoptosis-related genes triggered cell death in haploid cell cultures. Thus, we can derive haploid somatic cells by manipulating apoptosis gene, facilitating genetic screens of lineage-specific development.

Expression data from haploid and diploid epiblast stem cells

Project description:Haploid pluripotent stem cells, such as haploid embryonic stem cells (haESCs), facilitate the genetic study of recessive traits. In vitro, fish haESCs maintain haploidy in both undifferentiated and differentiated states, but whether mammalian haESCs can preserve pluripotency in the haploid state has not been tested. Here, we report that mouse haESCs can differentiate in vitro into haploid epiblast stem cells (haEpiSCs), which maintain an intact haploid genome, unlimited self-renewal potential, and durable pluripotency to differentiate into various tissues in vitro and in vivo. Mechanistically, the maintenance of self-renewal potential depends on the Activin/bFGF pathway. We further show that haEpiSCs can differentiate in vitro into haploid progenitor-like cells.

A genetic screen identifies Etl4-deficiency capable of stabilizing the haploidy in embryonic stem cells

Project description:We performed a genome-wild loss-of-function screening and revealed several gene mutations could significantly reduce the rate of self-diploidization in haESCs. We further demonstrated that CRISPR/Cas9 mediated Etl4 knockout stabilizes the haploid state in different haploid cell lines. More interestingly, Etl4 deficiency could increase the mitochondrial oxidative phosphorylation (OXPHOS) capacity and decrease glycolysis in haESCs. Collectively, our study identifies Etl4 as a novel haploidy-related factor and suggests that the changes of energy metabolism is associated with self-diploidization.

Genetic screening and multipotency in rhesus monkey haploid neural progenitor cells

Project description:Haploid embryonic stem cells (haESCs) have been extensively applied in forward and reverse genetic screening. However, a mammalian haploid somatic cell line is difficult to achieve because of spontaneous diploidization in differentiation. As a non-human primate species, monkeys are widely used in basic and pre-clinical research in which haploid cells are restricted to ESCs. Here, we report that rhesus monkey haESCs in an optimized culture medium show naïve-state pluripotency and stable haploidy. This model facilitated the derivation of haploid neural progenitor cells (haNPCs), which maintained haploidy and differentiation potential into neurons and glia for a long period in vitro. High-throughput trapping mutations can be efficiently introduced into haNPCs via piggyBac transposons. This system proves useful when identifying gene targets of neural toxicants via a proof-of-concept experiment. Using CRISPR/Cas9 editing, we confirmed that B4GALT6, from the candidate gene list, is a resistance gene of A803467 (a tetrodotoxin-like toxicant). This model is the first non-human primate haploid somatic cell line with proliferative ability, multipotency and an intact genome, thus providing a cellular resource for recessive genetic and potential drug screening.

Reduced diploidization and survival improvement of semi-cloned mice produced from androgenetic haploid embryonic stem cells

Project description:We found that the overall DNA methylation and hydroxymethylation in AG-haESCs are extremely low, and the downregulation of both de novo methyltransferase Dnmt3b and methylation maintenance enzyme Dnmt1was discovered responsible for this DNA hypomethylation. Further, our study discovered that the correction of DNA methylation can greatly reduce the incidence of diploidization and further improve the survival of semi-cloned mice produced from AG-haESCs.

Chromatin landscapes in mouse haploid stem cells [RRBS-seq]

Project description:We generate histone modification profiles and DNA methylation profiles of mouse haploid embryonic stem cells. By comparison to mouse diploid ESCs and MEFs, we found the similar chromatin landscapes between haESCs and mESCs, which reveal the self-renew ability and pluripotency in haESCs. Besides, haESCs specific chromatin landscapes show its sperm-like functions.

CGH analysis of AG-haESCs (androgenetic haploid embryonic stem cells)

Project description:The genomic DNA sample of AG-haESCs were compared to the C57BL/6J male mouse kidney by comparative genomic hybridization. The data confirmed that the haploid cells sustained genome integrity. The analysis was performed on a NimbleGen Mouse CGH 3x720K Whole-Genome Tiling Array to analyse the copy number variations in AG-haESCs, and the genomic DNA of C57BL/6J male mouse kidney was used as control, which had the same background with haploid ESCs.

Epigenetic integrity of paternal imprints enhances the developmental potential of androgenetic haploid embryonic stem cells

Project description:The use of two inhibitors of Mek1/2 and Gsk3β (2i) promotes the generation of mouse diploid and haploid embryonic stem cells (ESCs) from the inner cell mass of biparental and uniparental blastocysts, respectively. However, a system enabling long-term maintenance of imprints in ESCs has proven challenging. Here, we report that usage of a two-step a2i (alternative two inhibitors of Src and Gsk3β, TSa2i) derivation/culture protocol results in the establishment of androgenetic haploid ESCs (AG-haESCs) with stable DNA methylation at paternal DMRs (differentially DNA methylated regions) up to passage 60 that can efficiently support generating mice upon oocyte injection. We also show coexistence of H3K9me3 marks and ZFP57 bindings with intact DMR methylations. Furthermore, we demonstrate that TSa2i-treated AG-haESCs are a heterogeneous cell population regarding paternal DMR methylation. Strikingly, AG-haESCs with late passages display increased paternal-DMR methylations and improved developmental potential compared to early-passage cells, in part through the enhanced proliferation of H19-DMR hypermethylated cells. Together, we establish AG-haESCs that can long-term maintain paternal imprints.
