Project description:Neural formation from ES cells provides a novel system for studying axonogenesis in projection neurons. We used microarrays to clarify the global gene expression patterns of ES-derived motoneurons and compared with the parental undifferentiated ES cells. HB9-GFP ES cells on day 7 were mechanically pipetted into small cell clumps and concentrated to a density of approximately 1Ã104 cells/μl in neural differentiation medium. The animals received total laminectomy from T8 to T10. Total RNA was extracted from the undifferentiated ES cells (1531), the sorted HB9-GFP+ cells (1557), the sorted sox1 neural stem cells (1602) and the mouse cerebellar granule cells (1532) on postnatal day 6 and performed hybridization on Affymetrix microarrays.

Project description:We investigated microRNA expression in motoneurons by performing small RNA sequencing of fluorescence-activated cell sorting (FACS)-isolated motoneurons labelled with the Hb9:gfp transgenic reporter and Hb9:gfp negative non-motoneurons including spinal interneurons. We find that one microRNA, microRNA-218, is highly enriched and abundantly expressed in motoneurons. Furthermore, we find that miR-218 is transcribed from alternative, motoneuron-specific alternative promoters embedded within the Slit2 and Slit3 genes by performing RNA sequencing of FACS-isolated motoneurons and a dissected embryonic floor plate cells which served as a control. Next, we performed RNA sequencing of FACS-isolated wild type (WT) motoneurons and motoneurons lacking miR-218 expression (218DKO motoneurons), and find that a large set of genes (named 'TARGET218' genes) with predicted miR-218 binding sites are de-repressed in the absence of miR-218 expression. Finally, we examine the expression of TARGET218 genes in other neuronal subpopulations by FACS-isolating V1, V2a, and V3 interneurons expressing Cre-inducible fluorescent reporters and performing RNA sequencing. We find that the TARGET218 network of genes is depleted in wild-type motoneurons versus these interneuron types. Additionally, these genes are expressed at similar levels in 218DKO motoneurons compared with interneuron subtypes, suggesting that this genetic network.

Project description:In undifferentiated human ES cells, 5hr Met deprivation (delta Met) led to decreased proliferation, and prolonged 24hr Met deprivation resulted in G0-G1 phase cell cycle arrest, which then led to apoptosis. We used microarrays to detail the molecular mechanism of cell-death caused by Met deprivation in undifferentiated ES cells and checked the difference of Met cycle relate gene expression between undifferentiated human ES cells and ES cell derived endoderm.
