Gene expression data from mouse ES cell-derived primitive NSCs and definitive NSCs

ABSTRACT: Primitive neural stem cells (NSCs) could be derived from pluripotent mouse embryonic stem (ES) cells, and then differentiate into definitive-type neural stem cells which resemble NSCs obtained from the central nervous system. Hence, primitive NSCs define an early stage of neural induction and provide a model to understand the mechanism that controls initial neural commitment. In this study, we performed microarray assay to analyze the global transcriptional profiles in mouse ES cell-derived primitive and definitive NSCs and to depict the molecular changes during the multi-staged neural differentiation process.

Gene expression data from mouse ES cell-derived primitive NSCs and definitive NSCs

Hence, primitive NSCs define an early stage of neural induction and provide a model to understand the mechanism that controls initial neural commitment. In this study, we performed microarray assay to analyze the global transcriptional profiles in mouse ES cell-derived primitive and definitive NSCs and to depict the molecular changes during the multi-staged neural differentiation process. Primitive NSCs derived directly from ESCs in Lif (p-NSC_L), primitive NSCs that were sub-cultured in the presence of Lif and FGF (p-NSC_LF), as well as definitive NSCs derived from primitive NSCs in medium containing FGF and EGF, were collected for RNA extraction and hybridization on Affymetrix microarrays. Mouse ESCs and NSCs obtained from mouse embryonic brain (E11.5) were included for controls. For each cell type, we collected two biological replicate samples for microarray analysis.

Fate specification of GFAP-negative primitive neural stem cells and their progeny at clonal resolution

Project description:The mature brain contains an incredible number and diversity of cells that are produced and maintained by heterogeneous pools of neural stem cells. Two distinct types of neural stem cells (NSCs) exist in the developing and adult mouse brain: GFAP (Glial Fibrillary Acid Protein)-negative primitive (p)NSCs and downstream GFAP-positive definitive (d)NSCs. To better understand the embryonic functions of NSCs, we performed clonal lineage tracing within neurospheres grown from either pNSCs or dNSCs to enrich for their most immediate downstream neural progenitor cells (NPCs). These clonal progenitor lineage tracing data allowed us to construct a hierarchy of progenitor subtypes downstream of pNSCs and dNSCs that were then validated using single cell transcriptomics. Further, we identify Nexn as required for neuronal specification from neuron/astrocyte progenitor cells downstream of rare pNSCs. Combined, these data provide single cell resolution of NPC lineages downstream of rare pNSCs that likely would be missed from population level analyses in vivo.

Characterization and generation of human definitive multipotent hematopoietic stem/progenitor cells

Project description:Definitive hematopoiesis generates hematopoietic stem/progenitor cells (HSPCs) that give rise to all mature blood and immune cells, but remains poorly defined in human. Here, we resolve human hematopoietic populations at the earliest hematopoiesis stage by single-cell RNA-seq. We characterize the distinct molecular profiling between early primitive and definitive hematopoiesis in both human embryonic stem cell (hESC) differentiation and early embryonic development. We generate definitive HSPCs from hESCs that hold the multipotency to differentiate various blood and immune cells, as validated by single-cell clonal assay. Strikingly, the generated HSPCs from hESCs give rise to various blood and lymphoid lineages in vivo. Lastly, we characterize gene-expression dynamics in definitive and primitive hematopoiesis and reveal an unreported role of ROCK-inhibition in enhancing human definitive hematopoiesis. Our study provides a prospect for understanding human early hematopoiesis and a firm basis to generate blood and immune cells for clinical purposes.

Expression data from hiPSCs-NSCs towards 4T1

Project description:Neural stem cells can migrate towards tumors of both neural and non-neural origins, which is crucial for the success in treating disseminated tumors. Although the understanding of the molecular mechanisms underlying NSC tumor tropism is limited, it has been noted that several cytokines, growth factors and receptors direct the migration in vitro. A proper understanding of the basic molecular mechanisms of NSC migration towards tumors, especially identification of key cellular regulators of the migration, will have important implications in improving the effectiveness of engineering and employing NSCs as tumor therapy agents. We compared gene expression profiles between migratory and non-migratory hiPSC-NSCs towards cancer cells using cDNA microarray profiling. We collected human iPSCs derived NSCs migrating and not migrating towards mouse 4T1 breast cancer cells in an in vitro migration system for total RNA extraction and hybridization to Affymetrix microarrays

Naloxone influences NSCs proliferation and differentiation

Project description:Naloxone is an opioid-receptor antagonist used to reverse the effects of opioid.In our study, we treated NSCs (neural stem cells) with naloxone and damgo (a selective μopioid receptor agonist), and examined their effects on NSCs proliferation and differentiation.Naloxone was found to promote NSCs proliferation and neural differentiation, while the effects of damgo was very week. The results suggested that naloxone may work indepedent of opioid receptors. To investigate the underlying mechanisms, RNA-seq was conducted. For proliferation analysis,p8 NSCs were cultured with or without naloxone or damgo for 3 days. For differentiation analysis,p8 NSCs was induced to differentiate with or without naloxone or damgo, samples on D2,4,8 were collected and analyzed.
