Project description:We report the differential roles of an HDAC inhibitor-TSA during hESC nerual commitment. In the initiation of hESC differentiation, TSA could inhibit the downregulation of pluripotency genes to maintain pluripotency, whereas in the neural commitment stage, TSA could promote neural gene expression to assist hESC nerual determination. Examination of gene expression patterns in hESCs, day 4 or day 8 differentiated cells without or with TSA treatment

Project description:While the transcriptional network of human embryonic stem cells (hESCs) has been extensively studied, relatively little is known about how post-transcriptional modulations determine hESC function. RNA-binding proteins play central roles in RNA regulation, including translation and turnover. Here we show that the RNA-binding protein CSDE1 is highly expressed in hESCs to maintain their undifferentiated state and prevent default neural fate. Notably, loss of CSDE1 accelerates neural differentiation and potentiates neurogenesis. Conversely, ectopic expression of CSDE1 impairs neural differentiation. We find that CSDE1 post-transcriptionally modulates core components of multiple regulatory nodes of hESC identity, neuroectoderm commitment and neurogenesis. Among these key pro-neural/neuronal factors, CSDE1 binds fatty acid binding protein 7 (FABP7) and vimentin (VIM) mRNAs as well as transcripts involved in neuron projection development regulating their stability and translation. Thus, our results uncover CSDE1 as a central post-transcriptional regulator of hESC identity and neurogenesis.

Project description:Effect of ionizing radiation on transcriptome during neural differentiation of hESC
| PRJNA573089 | ENA
Project description:The aim of the dataset was to study on genome-wide level the effect of Notch inhibition in gene expression on neural crest differentiation of human embryonic stem cells under chemically defined conditions. Total RNA from hESCs, hESC-derived neural crest, hESC-derived neural crest+DAPT, and hESC-derived neural stem cells was collected and compared at their global gene expression level. Samples from 3 biological replicates were analysed.

Project description:The self-renewal and differentiation potential of human embryonic stem cells (hESCs) suggests that hESCs could be used for regenerative medicine, especially for restoring neuronal functions in brain diseases. However, the functional properties of neurons derived from hESC are largely unknown. Moreover, since hESCs were derived under diverse conditions, the possibility arises that neurons derived from different hESC lines exhibit distinct properties, but this possibility remains unexplored. To address these issues, we developed a protocol that allows step-wise generation from hESCs of ~70-80% pure human neurons that form spontaneously active synaptic networks in culture. Comparison of neurons derived from the well-characterized HSF1 and HSF6 hESC lines revealed that HSF1- but not HSF6-derived neurons exhibit forebrain properties. Accordingly, HSF1-derived neurons initially form primarily GABAergic synaptic networks, whereas HSF6-derived neurons initially form glutamatergic networks. microRNA profiling revealed significant expression differences between the two hESC lines, suggesting that microRNAs may influence their distinct differentiation properties. These observations indicate that although both HSF1 and HSF6 hESCs differentiate into functional neurons, the two hESC lines exhibit distinct differentiation potentials, suggesting that they are pre-programmed. Information on hESC line-specific differentiation biases is crucial for neural stem cell therapy and establishment of novel disease models using hESCs. Keywords: Gene expression profiling

Project description:In this research we have done a comprehensive transcripteome analysis of hESC differentiation at three different stages: early neural differentiation, neural ectoderm, and mature neurons. We detected and validated time-dependent gene expression patterns and represented that the gene expression patterns exhibit early ESC differentiation. Pathway analysis revealed dynamic expression patterns of members of several signaling pathways. The hESC cells were passaged every 7 days using collagenase/dispase and cultured under feeder-free culture conditions on Matrigel in hESC medium. Three biological replicates per time point served as the input to generate biotin-labeled cRNA using a linear amplification kit.

Project description:Differentiation of hESCs to neural lineages was used as a model for early embryonic brain development in order to assess the effect of their exposure to low (17 mGy) and high (572 mGy) doses of radiation on gene expression. Exposure of hESC to the low dose did not result in changes in gene expression at any of the time points, whereas exposure to the high dose resulted in downregulation of some major neurodifferentiation markers on days 6 and 10. Gene ontology analysis showed that pathways related to nervous system development, neurogenesis, and generation of neurons were among the most affected. Conclusion: exposure to a low dose of 17 mGy was well tolerated by hESCs while exposure to 572 mGy significantly affected their genetic reprogramming into neuronal lineages.

Project description:To assess the effects of quantitative TWIST1 dosage changes on chromatin accessibility in hESC-derived cranial neural crest cells, we performed genome editing of the H9 hESC lines to tag TWIST1 with FKBPV36 and V5, Upon differentiating edited hESC to cranial neural crest cells using an established protocol, addition of differing concentrations of the degrader molecule dTAGV-1 results in different TWIST1 concentrations, as measured by V5 intracellular staining and flow cytometry. We then profiled chromatin accessibility in each of these TWIST1 concentrations
