Project description:Rudhira is essential for mouse developmental angiogenesis and tissue morphogenesis. Embryos lacking endothelial rudhira die at mid-gestation with vascular patterning defects. Rudhira mutant yolk sac endothelial cells show slow and random migration. So to identify key signaling pathways perturbed in the absence of rudhira, we undertook whole transcriptome based analysis of gene expression in rudhira null yolk sac and embryo. Transcriptome analysis shows that key mediators of angiogenesis, cell adhesion, migration and extracellular matrix degradation as well as several components of the TGFβ pathway are perturbed in rudhira null mutant yolk sacs at 9.5 dpc.

We used two embryo samples ( 2E- wild type; 5E- rudhira mutant). Repetition was done on each sample. We used 4 yolk sac samples (3Y,4Y- wild type; 7Y,8Y-rudhira mutant) for the analysis. Repetition was done on each sample.

Project description:PRDM6 belongs to the PRDM family of transcriptional repressors that all contain a PR domain and Zinc finger domains. Prdm6 has transcriptional repressor activity. Prdm6 may regulate factors that are involved in the differentiation / proliferation of smooth muscle cells, promoting proliferation. PRDM6 knockouts are embryonic lethal around 12.0 dpc knockout embryos eventually develop edema: cardiovascular defect vascularization defect in the yolk sac: dysorganized angiogenesis Keywords: cDNA array, yolk sac, murine embryo E10.5

Project description:CIRHIN is a transcription co-factor, shows postive effect on Hiv-1 LTR enhancer element(NF-κB site); and Cirh1a null is preimplantation lethal, but highly expressed in the early mice embryo (E6.0-E12.5). We hypothesis that Cirh1a's effect on gene transcription of early embryo can be detected with Cirh1a down regulated in Cirh1a+/- state. Result shows that Cirh1a+/- has significant effect on early mice embryo gene transcription, Differentially expressed genes (DEGs) detected are mainly involved in cell proliferation/differenciation, cell cycle progress, embryo development and multi-orgnaogenesis. Littermate embryos (E8.5) were dissected into RNAlater reagent for total RNA extraction, and yolk sac was used for genotyping PCR. Littermate embryos (E9.5) were dissected into RNAlater reagent for total RNA extraction, and yolk sac was used for genotyping PCR. Liver buds from littermate embryos (E11.5) were dissected into RNAlater reagent for total RNA extraction, and yolk sac was used for genotyping PCR. Liver buds from littermate embryos were dissected into RNAlater reagent for total RNA extraction, and yolk sac was used for genotyping PCR.

Project description:Investigating the blood, immune and stromal cells present in a human fetal embryo in a world first single cell transcriptomic atlas. The embryo was dissected into 12 coronal sections, yolk sac, and yolk sac stalk. Live single cells sorted, with cell suspension then undergoing 10x chromium 5 prime scRNA-seq. This accession contains the yolk sac and yolk sac stalk data from this embryo. A matched accession contains the coronal section data. Lane "WS_wEMB12142156" (from yolk sac) was excluded from downstream analysis due to low fraction reads in cells post-CellRanger QC. Termination procedure for this embryo was medical. The F158_[features...barcodes...matrix].[tsv...mtx].gz files attached to this accession represent raw count data from all the 10x lanes in this accession combined, and as output from CellRanger filtered matrices (CellRanger version 6.0.1 using human reference genome GRCh38-2020-A). One set of count matrices relates to the yolk sac data, and one set of count matrices relates to the yolk sac stalk data.

Project description:This study aimed at exploring the physiological function of mammalian HYPB by means of knockout mouse model. Homogenous disruption of mouse Hypb gene leads to embryonic lethality at E10.5-E11.5. Severe vascular defects were observed in the Hypb-/- embryos, yolk sac and placenta.In the mutant embryo and yolk sac, disorganized and abnormally dilated capillaries cannot be remodeled into large blood vessels or intricate networks. Thus, our results suggest that the mammalian HYPB HMT plays an important role in embryonic vascularization. Keywords: knockout, mouse embryo development, angiogenesis, yolk sac, E9.0, E10.5

Project description:A gene expression study using microarray analysis was performed to elucidate the underlying mechanism leading to embryonic lethality in homozygous Commd1 null (Commd1-/-) mouse embryos. A gene expression profile of 9.5 dpc Commd1-/- embryos were generated and were compared to a gene expression profile of both 8.5 dpc and 9.5 dpc normal embryos.

Project description:The signaling cascades that direct the morphological differentiation of the vascular system during early embryogenesis are not well defined. To further understand the role of Notch signaling during endothelial differentiation, this study uses both an in vivo gain-of-function and in vivo loss-of-function approach. At embryonic day 9.5, embryos with activated Notch1 signaling in the endothelia display a variety of growth and cardiovascular defects, and die soon after E10.5. Most notably, the extra-embryonic vasculature of the yolk sac displays remodeling differentiation defects. In the wild-type yolk sac, the primary vascular network has begun to reorganize, forming the large primary vessels and the smaller capillaries. In the activated Notch1 embryos remodeling is defective; the vasculature have an enlarged surface with decreased inter-vessel space. Embryos with ablated Notch signaling also display growth and vascular defects at E9.5 similar to the activated Notch1 embryos, however they exhibit a lack of vascular remodeling in the yolk sac, retaining the simple vascular plexus seen at E8.5. These results indicate that Notch signaling plays a critical role in the remodeling of the vasculature in the early embryo, particularly in the extra embryonic region. A conditional transgenic system was used in this study to activate Notch signaling. The ubiquitous ROSA26Notch transgene with a Neo/stop cassette flanked by loxP sites, followed by the N1-ICD cDNA, was recombined with a Tie2-CRE mouse, resulting in the removal of the STOP cassette and the subsequent activation of the Notch1-intracellular domain. This allowed for the overexpression and expansion of Notch signaling in all endothelial cells. Male Tie2-Cre mice were mated with female ROSA26Notch mice and resulting embryos were dissected at embryonic day 9.5. To ablate Notch signaling, Tie2-Cre mice were used in a two generation cross to obtain Tie2-Cre; Rbpj flox/flox embryos. These embryos lack RBPJ binding activity in the endothelia. In both instances embryos were used for genotyping and the yolk sac were separated and used to isolate total RNA with an RNeasy mini kit. The RNA was analyzed with the Mouse Genome 430A Array from Affymetrix. Samples were performed in duplicate, and RNA from wild type yolk sac tissues was compared to activated Notch and RBPJ loss-of-function yolk sac tissues.

Project description:Primitive erythropoiesis in the mouse yolk sac is followed by definitive erythropoiesis resulting in adult erythrocytes. In comparison to definitive erythropoiesis little is known about the genes that control the embryonic erythroid program. The purpose of this study was to generate a profile of mouse embryonic yolk sac erythroid cells and identify novel regulatory genes differentially expressed in erythroid compared to non-erythroid (epithelial cells). The identification of these genes will contribute to a greater understanding of how the primitive erythroid program is controlled. This work will have clinical implications for treating sickle cell anemia and β-thalassemia. Activating genes in adult erythroid cells that increase embryonic or fetal globin gene expression may be a therapeutic approach to treat individuals with these disorders.
