Project description:H1 ES cells were differentiated using a neural induction protocol. Biological triplicate samples were collected at five timepoints (d0, d3, d6, d9, d12) and analyzed by miRNA microarrays. The goal of this experiment was to identify potential biases in Drosha processing of miRNAs dependent on biophysical properties and to identify differentially expressed miRNAs over the course of differentiation/neural induction.

The goal of this experiment was to identify potential biases in Drosha processing of miRNAs dependent on biophysical properties and to identify differentially expressed miRNAs over the course of differentiation/neural induction. Using a robust differentiation protocol (described in the associated publication), H1 ES cells underwent differentiation/neural induction for 12 days. Samples were collected in biological triplicate every three days, beginning with day 0 and ending at day 12 for a total of five timpoints and fifteen samples. Total RNA was purified using the Qiagen miRNeasy Mini kit according to the manufacturer and submitted to LC Sciences according to their specifications. Raw data were received and were Lowess-normalized to allow cross-chip comparisons.

Project description:Sall4 is a transcription factor essential for early mammalian development. Though it is reported to play an important role in embryonic stem (ES) cell self-renewal, whether it is an essential pluripotency factor has been disputed. Though Sall4 is known to associate with the Nucleosome Remodeling and Deacetylase (NuRD) complex, the nature of this interaction is unclear as NuRD and Sall4 serve opposing functions in ES cells. Here we use defined culture conditions and single-cell gene expression analyses to show that Sall4 prevents activation of the neural gene expression programme in ES cells but is dispensable for maintaining the pluripotency gene regulatory network. We further show using genome-wide analyses that while Sall4 interacts with NuRD, it neither recruits NuRD to chromatin nor influences transcription via NuRD. Rather we propose a model where, by titrating Sall4 protein, NuRD limits the differentiation-inhibiting activity of Sall4 in ES cells to enable lineage commitment.

Project description:To capture the Zeb2-dependent transcriptional changes in early cell state/fate decisions we performed RNA-seq on Zeb2 control and Zeb2 knockout cells. We chose three stages, which correspond in control ESCs to the naive pluripotent state (d0; very low amounts of Zeb2 mRNA), multipotent progenitors (d4, low Zeb2 mRNA/protein) and early neural progenitors (d6, high Zeb2 mRNA/protein), respectively.

Project description:Human embryonic stem cells not only provide a continuous cell source for potential cell therapy but also offer a system to unveil events of embryonic development in humans. This proposal will examine how the earliest neural cells, neuroepithelia, are specified from the naïve ES cells, and test the hypothesis that neural specification in humans employs a similar mechanism as in other vertebrates. We will first re-create in culture the developmental events of the first 2-3 weeks of human embryonic development during which ES cells will be differentiated through the stages of embryoid bodies, primitive ectoderm cells, neural tube-like rosette cells. The stage-specific events will be defined by DNA microarray analysis along with the characteristic morphologic changes. This study will lead to an optimized procedure for generating enriched neural precursor cells, which will lay the groundwork for potential use of human ES cells in the treatment of neurological injuries and diseases. Aim 1: Establish a stepwise neural differentiation system from human ES cells. Aim 2. Determine the mechanism of Neural Specification in humans. Aim 3: Define the identity and function of ES cell-derived neural precursor cells. ES cells offer an alternative approach to study early developmental events in humans. This however requires re-creating the neural differentiation process in culture. Cell fate specification is determined by interactions between environmental factors and intrinsic signals. Our preliminary data suggest that the temporal pattern of neural differentiation and, to some degree, the spatial organization of neural precursors from human ES cells recapitulate in vivo neural development. We hypothesize that the intrinsic neural specification program may be preserved in culture, which offers a controlled system to examine the effect of extrinsic signals on neural specification. Distinctive morphological changes along the neural differentiation pathway are presumably accompanied by molecular changes. DNA microarray analysis will be used to determine the gene expression pattern by cells at each of the given stages. By analogy with early embryonic development and using morphological and antigenic markers, we can now subdivide the human ES cell neural differentiation process into four identifiable stages: ES, EB, PEL cells, and neural rosette cells. This definition is based on the assumption that early human development is the same as in other species, and employs the limited known markers from mouse ES cells. We will systematically investigate the molecular profile of cells at each of the neural differentiation stages using DNA microarray analysis. Total RNAs will be extracted from cells at the following developmental stages: ES cells, EBs grown in suspension (d6), PEL (d10) stage and neural rosettes (d17). Since the neural rosette culture contains non-neural lineage cells, we will separate the neural rosette cells from the surrounding non-neural cells through differential enzymatic response and differential adhesion. Three independent biological replicates consisting of three pooled experiments will be run for each of the four developmental time points, for a total of twelve chips. Keywords: time-course
