Project description:We have developed a novel in vitro protocol for the derivation of bona fide Pharyngeal Endoderm (PE) cells from hESCs. We demonstrated that our PE cells robustly express Pharyngeal Endoderm markers, they are transcriptionally similar to PE cells isolated from in vivo mouse development and represent a transcriptionally homogeneous population. Importantly, we elucidated the contribution of Retinoic Acid in promoting a transcriptional and epigenetic rewiring of PE cells. In addition, we defined the epigenetic landscape of PE cells by combining ATAC-Seq and ChIP-Seq of histone marks.

Project description:Introduction: To determine the miRNA expression profile in placentas complicated by Preeclampsia (PE) and compare it to uncomplicated pregnancies. Methods: Sixteen placentas from women with PE, including 11 with early onset PE (EOPE) and 5 with late onset PE (LOPE), as well as 8 from uncomplicated pregnancies were analyzed using miRNA microarrays. For statistical analyses the MATLAB® simulation environment was applied. The over-expression of miR-518a-5p was verified using Quantitative Real-Time Polymerase Chain Reaction. Results: Overall, 44 miRNAs were found deregulateddysregulated in PE complicated placentas. Statistical analysis revealed that miR-431, miR-518a-5p and miR-124* were over-expressed in EOPE complicated placentas as compared to controls whereas miR-544 and miR-3942 were down-regulated in EOPE. When comparing the miRNA expression profile in cases with PE and PE- growth restricted fetuses (FGR), miR-431 and miR-518a-5p were found over-expressed in pregnancies complicated by FGR. Additionally, up- regulation of miR-124, miR-423-3p and miR-518a-5p was associated with proteinuria. Discussion: Specific miRNAs can differentiate EOPE and LOPE from uncomplicated pregnancies representing putative PE-specific diagnostic biomarkers. Among them, miR-518a-5p emerged as a potential diagnostic indicator for EOPE cases as well as for FGR and proteinuria associated PE complicated placentas designating its potential link to the severity of the disease.

Project description:Introduction: To determine the miRNA expression profile in pregnancies complicated by Preeclampsia (PE) and compare it to uncomplicated pregnancies. Methods: Seventeen placentas from women with PE, [all of them being late onset PE (LOPE)], as well as 17 placentas from uncomplicated pregnancies were analyzed using miRNA NGS. For statistical analyses the MATLAB® simulation environment was applied. The expression of miR-99b and miR-23b were verified using Quantitative Real-Time Polymerase Chain Reaction. Results: Two miRNAs were found dysregulated in PE complicated placentas. Statistical analysis revealed that miR-99b and miR-23b were under-expressed in complicated placentas as compared to controls. Discussion: Since specific miRNAs can differentiate complicated from uncomplicated pregnancies, they may be considered as putative PE-specific biomarkers.
