Differential expression between floor plate and ventral lateral region in E10.5 mouse embryo midbrain

ABSTRACT: The data revealed differential expression between floor plate and ventral lateral region in E10.5 mouse embryo midbrain. Several differentially expressed genes in these regions have been reported in the literature, demonstrating reliability of tissue dissection. Midbrain floor plate and non-overlapping adjacent ventral lateral region of mouse E10.5 embryo midbrain was dissected. Each sample was a pool from 6 embryos. Three replicates for each region were used for the experiment.

Doublesex and mab-3-related transcription factor 5 promotes midbrain dopaminergic identity in pluripotent stem cells by enforcing a ventral-medial progenitor fate.

Understanding the control of cell-fate choices during embryonic stem cell (ESC) differentiation is crucial for harnessing strategies for efficient production of desired cell types for pharmaceutical drug screening and cell transplantation. Here we report the identification of the zinc finger-like doublesex and mab-3-related transcription factor 5 (Dmrt5) as a marker for mammalian ventral-medial mesencephalic neuroepithelium that give rise to dopamine neurons. Gain- and loss-of-function studies i ...[more]

Overexpression of Dmrt5 in in vitro differentiated neural progenitor cells regulates gene expression

Project description:To test the regulatory effects of Dmrt5 on gene expression, we designed tetracycline inducible lines of Dmrt5 transgenic mouse ESCs. Overexpression of Dmrt5 was induced upon addition of Doxycycline (Dox). To evaluate the effects of Dmrt5 on gene expression in different stages of in vitro differentiated NPC derived from mouse embryonic stem cells (ESC), we analyzed gene expression profiles at differentiation day 7 and day 9 with or without Dox. The data revealed that overexpression of Dmrt5 in in vitro differentiated neural progenitor cells (NPC) regulates gene expression. Addition of Dox to the medium of the control cell line rtTA did not significantly alter gene expression profile, demonstrating that the observed effects were through induction of Dmrt5, but not simply through Dox. A tetracycline-inducible rtTA-Dmrt5 ES cell line and the parental rtTA cell line were used for the experiment. These ES cells were differentiated using a monolayer differentiation (MD) protocol in N2B27 medium. At MD day 5, cells were treated with Dox or without. RNA was extracted from cells harvested at MD day 7 and day 9. Two replicates for each group were used for the experiment.

Expression data from early and late born Atoh1 lineages within the E14.5 rhombomere 1 and isthmus

Project description:Following neural tube closure at around E9.5, the rhombic lip within the rhombomere 1/isthmus region ("upper rhombic lip") produces a sequence of neuronal lineages that populate the brainstem and cerebellum. The transcription factor Atoh1 (Math1) is required for this specialized neurogenesis, although the genetic programs that delineate the temporal cell fate changes downstream of Atoh1 are not well characterized. We examined the gene expresion changes that take place within Atoh1 lineages We purified early (E10.5) and late (E13.5) born Atoh1 expressing cells from E14.5 embryos using a transgenic labeling strategy, and analyzed differences in gene expression across the two populations using the microarray data shown below.

Transcription profiling of dopaminergic neurons of the substantia nigra pars compacta (SNc) and the ventral tegmental area from normal rats

Project description:The cardinal clinical features of Parkinson's disease result from selective loss of midbrain dopaminergic neurons. The goal of this experiment is to determine the gene expression profiles of these neurons by studying untreated rat substantia nigra pars compacta (SNc) and ventral tegmental area (VTA) dopaminergic neurons using laser capture microscopy to obtain region-specific neuronal mRNA.

Expression data from E10.5 mouse otocyst

Project description:We established a novel EGFP reporter mouse line (named Tg(ETAR-EGFP)14Imeg), which enables the placode-derived inner ear sensory cell lineage to be visualized and monitored. At E10.5, EGFP expression was detected in the ventral and dorsomedial region of the otocyst. Using this reporter line and FACS-array technology, we performed gene expression profiling focused on the regional specificity of the otocyst. We sorted E10.5 otocyst epithelial cells of heterozygous mice into EGFP-positive and EGFP-negative cells for RNA extraction and hybridization on Affymetrix microarrays. We profiled the expression of the genes in FACS-enriched cell population and conducted transcriptome analysis.

Single-cell sequencing of human induced pluripotent stem cell-derived ventral midbrain astrocytes

Project description:Regional specificity of stem cell-derived astrocytes is believed to be an important prerequisite for their applications in disease modelling and cell-based therapies. The regional identity of these astrocytes is often defined by the positional characteristics of their antecedent, stem cell-derived neural progenitors patterned to a fate of interest, with the assumption that the positional specification is to be preserved by the derived astrocytes. Using a human iPSC line designed for tracing midbrain floor plate derivatives, here we show that lineage composition of the derived astrocytes is not a faithful recapitulation of the founder progenitor population, as demonstrated by the loss of floor plate differentiated progeny in the final astrocyte products. Using deep single cell RNA sequencing, we identified distinct transcriptomic signatures of midbrain floor plate-derived astrocytes. Our study highlights the need for rigorous characterisation of PSC-derived regional astrocytes and provides a valuable resource for assessing midbrain floor plate-derived human astrocytes.

ChIP-seq analysis of Foxa2 binding sites in midbrain dopaminergic progenitors

Project description:Embryonic stem (ES) cells were differentiated in culture to midbrain dopaminergic (mDA) progenitors and subjected to ChIP-seq analysis to resolve genome-wide binding sites of forkhead box protein A2 (Foxa2). Foxa2 was found to directly regulate multiple lineage pathways to specify midbrain dopaminergic and floor plate progenitor identity.

Gene expression analysis of midbrain dopamine progenitors in embryonic mouse

Project description:To improve the standardization of cell therapies for Parkinson’s disease, methods for the selection and isolation of midbrain dopaminergic progenitors for transplantation are required. To facilitate this we established an expression profile for genes selectively expressed on transplantable midbrain dopaminergic progenitors using microarray analysis. Expression of GFP in the ventral mesencephalon of embryonic E12.5 Ngn2-GFP mice identifies a distinct sub-population of cells containing virtually all of the midbrain dopaminergic progenitors. Gene expression profiles from 3 biological replicates of FACS isolated GFP-positive cells from mouse Ngn2-GFP ventral mesencephalon were generated using microarrays. To reduce the likelihood of identifying transcripts from non-dopaminergic progenitors, 3 biological replicates of FACS isolated GFP-negative cells from mouse Lmx1a-GFP ventral mesencephalon (definitively non-dopaminergic) were used as a reference population.
