The regulation and molecular programs during embryonic neural development have long been investigated. Since the development of human ESCs and iPSCs, the ability to investigate human neurogenesis and neurological diseases via an in vitro differentiation model has vastly ngi [ 417 ].

Bfi transcriptomics of the human placenta: Simple combinations of lineage-determining transcription factors prime cis-regulatory elements required for macrophage and B cell identities. Karyotype analysis results The fetus and both parents had normal karyotypes.

Our study provides a comprehensive and integrative study of the transcriptomics and epigenetics of human early neural differentiation, which paves the way for a deeper understanding of the regulatory mechanisms driving the differentiation of the neural lineage.

Support Center Support Center. The interactomes among Ros-L cells, with 31, 32, and 34 receptors from Ros-L1, Ros-L2, and Ros-L3 interacting with ligands from other cell subpopulations, were 703 Fig. The primary antibodies for respective cells include OCT4 1: Of note, there was a clear divarication within the rosette stages Ros-E and Ros-L across the differentiation trajectory, indicating cell fate decision might be made at this bifurcation point Fig.

A high-resolution map of the three-dimensional chromatin interactome in human cells. The subsequent bioinformatic analysis revealed that there were two disease-causing genes known in this fragment.

Notably, our study reveals the regulatory network of TFs that are differentially expressed among neighboring cell subpopulations to be likely candidates for promotion of cell fate transition. We assumed that those peaks, conserved among differentiation stages, are associated with housekeeping genes, while stage-dynamic peaks are likely to vgi cis -regulatory elements important for cell status transition.


The helix-loop-helix protein Id1 controls stem cell proliferation during regenerative neurogenesis in the adult zebrafish telencephalon. SS16 bbi Additional file Noninvasive prenatal testing Five milliliters of maternal peripheral blood was collected into a blood collection tube containing ethylenediaminetetraacetic acid dipotassium salt EDTA-K2and the maternal plasma was separated and transferred into a new tube after centrifuging the sample at g for 10 min.

Platelet microparticles promote neural stem cell proliferation, survival and differentiation. We also applied scRNA-seq to our in vitro neural model to dissect the subpopulations present at each differentiation stage Fig.

To select key regulators, bti used a threshold of 5; all TFs with number of interactions above the threshold were considered as key regulators.

Karyotyping The amniotic fluid and the blood samples collected in this study were processed in parallel with cell culture and conventional karyotyping G-banding to exclude mosaic or balanced chromosome abnormalities. We then proposed that there was a high possibility for the fetus to have the same normal phenotype as the mother. In contrast, much fewer interactions were predicted after the EB stage, suggesting communications decreased dramatically during the progression of lineage commitment.

These results suggest that the expression patterns of neural-associated TFs undergo dramatic changes during neural differentiation with some TFs activated e. Cells were filtered using the following parameters: Non-invasive prenatal assessment of trisomy 21 by multiplexed maternal plasma DNA sequencing: Expression of this gene is associated with neural tube vgi in mice [ 3132 ], and we observed this gene to be highly expressed at Ros-E in human cells, suggesting that its role in neural tube closure may be conserved across mammals or possibly chordates.


After delivery, the normal phenotype of the newborn infant confirmed our prediction.

Genetic effects of a 13q31.1 microdeletion detected by noninvasive prenatal testing (NIPT)

Microdeletion and microduplication syndromes. To investigate whether this microdeletion originated from the fetus, the mother, or both, we collected fetal amniotic fluid and blood samples from the parents, and aCGH was used to validate this finding and its origin. Using these criteria, we predicted thousands of targets for the inferred TFs Additional file Author information Article notes Copyright and License information Disclaimer.

Perturbations in this delicately balanced and orchestrated process can result in neural tube defects NTDswhich give rise to birth defects such as spina bifida, anencephaly, and encephaloceles.

Single-cell exome sequencing reveals single-nucleotide mutation characteristics of a kidney tumor. To our knowledge, neural tube formation and closure are crucial for embryonic central nervous system CNS development and the process of neurulation. Array-based comparative genomic hybridization is more informative than conventional karyotyping and fluorescence in situ hybridization in the analysis of first-trimester spontaneous abortion.
