Deletion of CSF2RA in the bovine preimplantation embryo reduces development and affects embryonic gene expression in utero

ABSTRACT: The hypothesis that CSF2 plays a role in the preimplantation development of the bovine embryo was tested by evaluating consequences of deletion of CSF2RA (the functional receptor in the embryo) for development of embryos in utero. CRISPR/Cas9 was used to delete exon 5 and intron 5 of CSF2RA on chromosome 3. Control embryos were injected with Cas9 mRNA only. Embryos > 16 cells at day 5 after insemination were transferred to synchronized recipient females in groups of 7 to 24. Embryos were flushed from the uterus two days later. The proportion of recovered embryos that developed to the blastocyst stage was lower for knockout embryos (39%) than for control embryos (63%). RNA sequencing of individual morulae and blastocysts indicated a total of 27 (morula) or 15 (blastocyst) differentially-expressed genes (false discovery rate <0.05). Differentially-expressed genes as well as regulated gene sets identified by gene set enrichment analysis indicated that knockout affected genes playing roles in several functions including cell signaling and glycosylation. It was concluded that signaling through CSF2RA is not obligatory for development of the bovine preimplantation embryo to the blastocyst stage but that CSF2 signaling does enhance the likelihood that the embryo can become a blastocyst and result in specific changes in gene expression.

Colony stimulating factor 2 causes changes in the transcriptome of the bovine preimplantation embryo

Project description:The objective of this study was to identify changes on the CSF2 embryo transcriptome that make them more able to become a blastocyst and more likely to survive after transfer. Embryos were treated with CSF2 at day 5 after fertilization and at day 6 morulae and blastocysts were select for the microarray analysis. A total of 160 genes that had a 1.5-fold difference in expression and a significance of P M-bM-^IM-$ 0.05 could be annotated. Analysis of the data identified 13 biological process ontologies that could be grouped into four functional groups (development and differentiation process, cell communication, apoptosis and cell adhesion). Experimental conditions: CSF2 treated vs. CSF2 nontreated bovine in vitro produced preimplantation embryos. Biological replicates: CSF2 treated vs. nontreated bovine preimplantation embryos were used in a dye switch two-color microarray experimental design. Ratio data was not used in these experiments.

High-resolution Ribosome Profiling Reveals Translational Selectivity in Bovine Preimplantation Embryo Development

Project description:High resolution polysome fractionation and low-input ribosome profiling of bovine oocytes and preimplantation embryos has enabled us to define the translational landscape of early embryo development at an unprecedented level. We systematically and comparatively analyzed the transcriptome, polysome- and nonpolysome-bound RNA profiles of bovine oocytes and early embryos at 2-, 8-cell, morula, and blastocyst stage, and defined four modes of translational selectivity in bovine preimplantation embryo development: i. selective translation of non-abundant mRNAs, ii. active translating highly expressed mRNAs, iii. Translationally suppressed abundant mRNAs, and iv. Monosomaly occupied mRNAs. A strong selection towards genes involved in mitochondrial function and metabolic pathways was found throughout bovine preimplantation development. We found translatome largely follows transcriptome at oocytes, followed by a marked translational control at 8-cell embryos, which is gradually synchronized at the morula and blastocyst stage. We identified important novel cellular/embryonic functional regulators that being utilized and prioritized for translation at each developmental stage, that accompanies little-known bovine embryonic developmental programming. Together, these data reveal a unique spatiotemporal translational regulation that accompanies bovine preimplantation development.

Consequences of conceptus exposure to colony stimulating factor 2 on survival, elongation, interferon-{tau} secretion and gene expression

Project description:Exposure of bovine conceptuses to colony stimulating factor 2 (CSF2) from Day 5 to 7 of development can increase the percent of transferred conceptuses that develop to term. The purpose of this experiment was to understand the mechanism by which CSF2 increases embryonic and fetal survival. Conceptuses were produced in vitro in the presence or absence of 10 ng/ml CSF2 from Day 5 to 7 after insemination, transferred into cows, and flushed from the uterus at Day 15 of pregnancy. There was a tendency (P=0.07) for the proportion of cows with a recovered conceptus to be greater for those receiving a CSF2 treated conceptus (35% for control vs. 66% for CSF2). Antiviral activity in uterine flushings, a measure of the amount of interferon-{tau} (IFNT2) secreted by the conceptus, tended to be greater for cows receiving CSF2-treated conceptuses than for cows receiving control conceptuses. This difference approached significance when only cows with detectable antiviral activity were considered (P=0.07). In addition, CSF2 increased mRNA for IFNT2 (P=0.06) and keratin 18 (P<0.05) in extraembryonic membranes. Among a subset of filamentous conceptuses that were analyzed by microarray hybridization, there was no effect of CSF2 on gene expression in the embryonic disc or extraembryonic membranes. Results suggest that the increase in calving rate caused by CSF2 treatment involves, in part, more extensive development of extraembryonic membranes and capacity of the conceptus to secrete IFNT2 at Day 15 of pregnancy. Experimental conditions: CSF2 treated vs. CSF2 nontreated bovine in vitro produced preimplantation embryos were tranfered to a receptor cow and recovered at Day 15 of embryo development. The embryonic disc (ED) and the trophectoderm (Tr) were used for the expression analysis separately. Biological replicates: CSF2 treated vs. nontreated bovine preimplantation embryos were used in a dye switch two-color microarray experimental design.

Guide-free Cas9 is detrimental to pig preimplantation embryo development

Project description:Germline genome editing by the CRISPR/Cas9 system has potential for generation of genetically modified animals/the targeted correction of pathological mutations, understanding the mechanism of early embryonic development. Previous reports showed that Cas9 protein without sgRNAs could induce genomic damage in cell levels in vitro. However, whether the detrimental effects occurred in embryos after Cas9-treatment remains unknown. Here, by using pig embryos as the subjective, we found that Cas9 protein transcribed from injected Cas9 mRNA could persist to at least blastocyst stage. Cas9 protein alone could induce the genome damage of preimplantation embryos, represented by increased phosphorylated histone H2AX (pH2AX) foci on the chromatin fiber, leading to apoptosis and decreased cell number of blastocysts. In addition, single-blastocyst RNA sequencing confirmed that Cas9 protein without sgRNAs could also cause the blastocyst transcriptome changes, depressing the embryo development signal pathway, such as cell cycle, metabolism, and cellular communication related signal pathways, while activating apoptosis and necroptosis signal pathway, both of which together resulted in impaired the preimplantation embryonic development.

Transcriptomic differences in bovine blastocysts following vitrification and slow freezing at morula stage [EmbryoCryoSF]

Project description:This study aimed to compare the transcriptome of vitrified and slow frozen embryos with the untreated control. Bovine embryos (compact morulae) were vitrified or slow frozen and post-warm embryos were cultured to expanded blastocyst stage. The vitrified- and slow frozen-derived were subjected to microarray analysis and compared with untreated control embryos for differential gene expression. Morula to blastocyst conversion rate was higher (P<0.05) in control (72%) and vitrified (77%) embryos compared to slow frozen (34%) embryos. Total 20 genes were upregulated and 44 genes were downregulated in the vitrified embryos (fold change ≥ +-2, P<0.05). In slow frozen embryos, 102 genes were upregulated and 63 genes were downregulated (fold change ≥ +-1.5, P<0.05) in comparison with untreated embryos. Vitrified embryos exhibited significant changes in gene expression mainly involving embryo implantation (PTGS2, CALB1), lipid peroxidation and ROS generation (HSD3B1, AKR1B1, APOA1) and cell differentiation (KRT19, CLDN23). The slow frozen embryos, however, showed significant changes in the expression of genes related to cell signaling (SPP1), cell structure and differentiation (DCLK2, JAM2 and VIM), and lipid metabolism (PLA2R1 and SMPD3). In silico comparison between vitrified and slow-frozen (reference) embryos revealed similar changes in gene expression as between vitrified and untreated embryos. In conclusion, the vitrified bovine embryos demonstrated better post-warming embryo development than slow-frozen bovine embryos but their gene expression related to lipid metabolism, steroidogenesis, cell differentiation and placentation changed significantly. Slow freezing killed more embryos than vitrification, and the survived embryos did not express significant change in their gene expression.
