Global Transcriptional analysis of human spinal cord and neocortical neuroepithelial stem (NES) cells

ABSTRACT: We report the transcriptional profile of human spinal cord and neocortical neuroepithelial stem cells (SC-NES and NCX-NES cells) to identify potential engraftment markers in the lesioned spinal cord. We report that cells with a homologous neuroanatomical origin robustly integrate in the host tissue compared to cells with a different regional identity. Specifically, we describe that SC-NES cells display elective integration properties in the lesioned spinal cord compared to NCX-NES cells and that these properties are due to a combination of intrinsic and extrinsic factors. Upon transplantation, SC-NES cells differentiate into neurons and glial cells and extend lond-distance axons, whereas NCX-NES cells remain undifferentiated and display poor integration properties. SC-NES cell upregulate genes related to neurogenesis. In particular. we emphasize the upregulation of MTURN (maturin), ATCAY, PTN (pleiotropin), KAL1 (anosmin), SYT4 and SYT13.

Expression data from p53 knocked-down human neuroepithelial stem (NES) cells

Project description:In this study, we take advantage of human induced pluripotent stem (iPS) cell-derived neural stem cells to study the role of p53 during human brain development. We knocked down (KD) p53 in human neuroepithelial stem (NES) cells derived from iPS cells. Upon p53KD, NES cells rapidly show centrosome amplification and genomic instability. Gene expression analysis show downregulation of genes involved in oxidative phosphorylation (OXPHOS) upon loss of p53. In addition, p53KD neural stem cells upregulate genes involved in neuronal differentiation and display an increased pace of differentiating into neurons and exhibit a phenotype corresponding to more mature neurons compared to control neurons. Taken together, this demonstrates an important role for p53 in controlling genomic stability of neural stem cells and regulation of neuronal differentiation. We used microarrays to identify gene expression changes in human NES cells upon p53 knockdown

Genome-wide analysis of three clonal neural stem cell lines derived from human foetal spinal cord tissue.

Project description:Stem cells have received substantial interest both for their potential as in vitro tools to study development and as potential therapeutic agents in a range of degenerative diseases of the nervous system. We have generated clonal neural stem cell lines from human foetal spinal cord conditionally immortalised with 4-hydroxy tamoxifen inducible cMyc (cMycERTAM), and performed a detailed assessment of their identity in terms of their expression of homeodomain transcription factors and their capacity to generate particular neuronal subtypes of the spinal cord. These lines retain a ventral spinal cord progenitor phenotype and give rise to electrically active neuronal subtypes characteristic of specific ventral progenitor subdomains. Upon grafting into lesioned rat spinal cord these cells differentiate into ChAT+ve motorneurons and show robust survival after 4 months.

Generation of macrophages that are profoundly pro-remyelinating through unexpected activation cues

Project description:Excessive inflammation within the central nervous system is injurious, but an immune response is also required for its repair. Macrophages are versatile cells that adopt different properties depending upon their microenvironment. Exposing macrophages to interleukin-4 and -13 (IL4/IL13) has incurred interest for their reparative properties. Unexpectedly, while macrophages exposed to the classic pro-inflammatory signals (interferon-γ/lipopolysaccharide, IFN/LPS) killed neurons and oligodendrocytes in culture, the addition of LPS to IL4/IL13-treated macrophages profoundly elevated IL10, repair metabolites (lactate, ornithine), glucose metabolism and the oligodendrocyte-trophic heparin-binding epidermal growth factor (HBEGF); cells did not display pro-inflammatory or neurotoxic features. In mice with spinal cord demyelination, locally-applied IL4/IL13 was insufficient to alter responses beyond controls; remarkably, the LPS/IL4/IL13-treated animals significantly increased lesional phagocytic macrophages/microglia, lactate and HBEGF levels, oligodendrogenesis and remyelination. We report a remarkably reparative state of macrophages that is unexpectedly generated by the integration of pro- (LPS) and anti- (IL4/IL13) inflammatory activation cues.

Transcriptome analysis of single cell-derived hiPSC-lt-NES cell clones

Project description:To identify cell-populations within human iPSC-derived long-term self-renewing neural epithelial stem cells (hiPSC-lt-NES cells) which retain capacities to generate undesired grafts, we established single cell-derived hiPSC-lt-NES cell clones and performed gene expression microarray analysis.

Patterns of gene Expression during the Spinal cord Injury/Regeneration

Project description:Spinal cord injury (SCI) induces a sequence of endogenous autodestructive changes known as secondary injury, as well as reactive biochemical changes that are neuroprotective and/or promote recovery. All these responses to SCI are, in part re?ected in changes in gene expression. In order to assess changes in gene expression involved in the regeneration process,microarrays were performed as a function of time after SCI for the various treatments. Three groups rats(i.e.NT-3-chitosan tube group, tube alone group and lesion control group) used to interrogate Affymetrix (SantaClara,CA) GeneChips were sacrificed by intraperitoneally over dose injecting 6% chloral hydrate at 1, 3, 10, 20, 30, and 90 d after the operation. The spinal cords were surgically re-exposed and spinal tissue including dura and meninges was dissected into three blocks, i.e. 5 mm long segments in the lesioned area (M), rostral to the lesioned area (R), and caudal to the lesioned areas (C) were sampled under RNAase-free conditions. The samples were quick frozen and kept in liquid nitrogen.
