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.

Project description:We performed single-cell RNA-seq of human iPSC-derived long-term self-renewing neural epithelial stem cells (hiPSC-lt-NES cells) using Quartz-seq methods to characterize cellular heterogeneity .
Project description:CHARGE syndrome is a congenital disorder caused by mutations in Chromodomain Helicase DNA-binding domain 7 (CHD7) gene. We performed single cell RNA-seq analysis in CTRL and CHD7-knockdown lt-NES cells.
Project description:We performed a microarray experiment to analyze the transcriptional profile of human fetal tissue derived neural stem/progenitor cells, human iPSCs, or human iPSC-derived neural stem/progenitor cells generated using xenogenic or xeno-free reagents. Gene expression patterns were compared among human fetal tissue derived neural stem/progenitor cells, human iPSCs, or human iPSC-derived neural stem/progenitor cells generated using xenogenic or xeno-free reagents. Samples with a title including "Xf" (201B7-lt-NES (Xf)-1, 201B7-lt-NES (Xf)-2, 1210B2-lt-NES (Xf)-1,1210B2-lt-NES (Xf)-2, 1231A3-lt-NES (Xf)-1, 1231A3-lt-NES (Xf)-2) correspond to human iPSC-derived neural stem/progenitor cells generated using xeno-free reagents, whereas samples with a title including "Con" (201B7-lt-NES (Con)-1, 201B7-lt-NES (Con)-2) correspond to those generated using xenogenic reagents.
Project description:Schizophrenia is a debilitating neurological disorder for which no cure exists. Few defining characteristics of schizophrenic neurons have been identified and the molecular mechanisms responsible for schizophrenia are not well understood, in part due to the lack of patient material for study. Human induced pluripotent stem cells (hiPSCs) offer a new strategy for studying schizophrenia. We have created the first cell-based human model of a complex genetic psychiatric disease by generating hiPSCs from schizophrenic patients and subsequently differentiating these cells to hiPSC-derived neurons in vitro. Schizophrenic hiPSC-derived neurons showed diminished neuronal connectivity in conjunction with decreased neurite number, PSD95-protein levels and glutamate receptor expression. Gene expression profiles of schizophrenic hiPSC-derived neurons identified altered expression of many components of the cAMP and WNT signaling pathways. Key cellular and molecular elements of the schizophrenic phenotype were ameliorated following treatment of schizophrenic hiPSC-derived neurons with the antipsychotic loxapine. 3 independent differentiations (biological replicates) for each of four control and four schizophrenic patients were analyzed.
