Project description:In this report, we show that in addition to dual SMAD inhibition, blocking Glycogen synthase kinase 3(GSK3) signaling by adding CHIR99021 generated novel NPCs with significantly enhanced proliferation. By RNA-seq, we show that S/D/C NPCs and S/D NPCs display distinct expression profiles, as S/D/C triggered NPCs are Pax6- and express hindbrain genes while . S/D triggered NPCs are Pax6+ and highly express forebrain genes. Our data reveal that Pax6 labels distinct regionally specified hNPCs and manipulating GSK3 signaling could pattern hNPCs with positionally specified fate and different self-renewal capability.

Project description:Neural precursor cells (NPCs) are multipotent cells that can generate neurons, astrocytes, and oligodendrocytes in the mammalian central nervous system. Although Zbtb20 was expressed in NPCs, its functions in neural development are not fully understood. We performed microarray analysis to examine changes in gene expression between control and Zbtb20-overexpressed NPCs.

Project description:Neural precursor cells (NPCs) are multipotent cells that can generate neurons, astrocytes, and oligodendrocytes in the mammalian central nervous system. Although high mobility group nucleosomal binding domain 1 (HMGN1) was highly expressed in NPCs, its functions in neural development are not fully understood. We performed microarray analysis to examine changes in gene expression between control and HMGN1-overexpressed NPCs. NPCs derived from E11.5 mouse forebrains were infected with control or HMGN1 retrovirus in the presence of fibroblast growth factor 2 (FGF2) and epidermal growth factor (EGF). Three days after infection, the virus-infected NPCs were dissociated and seeded on poly-D-lysine -coated dishes, and subsequently the cells were cultured for 1 day without FGF2 and EGF.

Project description:Neural precursor cells (NPCs) in the mammalian neocortex generate various neuronal and glial cell types in a developmental stage-dependent manner. Most neocortical NPCs lose their neurogenic potential after birth. We have previously shown that high mobility group A (HMGA) proteins confer the neurogenic potential on early-stage NPCs during the midgestation period, although the underlying mechanisms are not fully understood. Here we performed microarray analysis and compared expression profiles between control and HMGA2-overexpressed NPCs.

Project description:Down syndrome neurophenotypes are characterized by mental retardation and a decreased brain volume. In order to identify whether deficits in proliferation, differentiation or survival could be responsible for this phenotype, neural precursor cells (NPCs) were isolated from the developing E14 neocortex of Down syndrome partial trisomy Ts1Cje mice and euploid (WT) littermates. Proliferation, cell differentiation and cell death assays revealed that Ts1Cje NPCs proliferated at a slower rate, due to a longer cell cycle and that a greater number of cells were positive for glial fibrillary acidic protein. An increase in Ts1Cje NPC cell death was also noted. Gene expression profiling was conducted on RNA extracted from Ts1Cje and WT NPCs. Approximately 54% of triploid gene expression ratios were significantly greater than the expected diploid gene ratio of 1.0. A number of diploid genes associated with differentiation, glial function and proliferation were dysregulated. The evidence points to a delay in cellular cycling that could exert stress on the NPC population, which might result in cellular death and a mobilization of glial cell survival responses. Importantly, these phenotypic changes, which mimic those seen in Down syndrome individuals, do not require over-expression of amyloid precursor protein (App) or soluble superoxide dismutase 1 (Sod1). In conclusion, early developmental proliferation deficits in Down syndrome result in secondary morphological changes that can impact on cognitive development and function.

Here we performed microarray analysis and compared expression profiles between control and HMGA2-overexpressed NPCs. Mouse neocortical neuroepithelial cells were isolated at embryonic day 11.5 and cultured as neurospheres for 9 days in vitro in the presence of fibroblast growth factor (FGF) 2 and epidermal growth factor (EGF). These cells were infected with control or HMGA2-expressing retrovirus, cultured in the presence of FGF and EGF for 3 days. Half of them were collected immediately for microarray analysis, and the other half were cultured in the absence of FGF for 12 h and then collected for microarray analysis.

Project description:We identified the Igfbpl1 gene by RNAseq of the neural precursor cells (NPCs) of the mice subventricular zone (SVZ), as an important gene released by SVZ-NPCs that play an important role in control of the striatal homeostasis and in particular involved in the cognitive processes and decision-making.

Project description:During development of the mammalian central nervous system (CNS), neurons and glial cells (astrocytes and oligodendrocytes) are generated from common neural precursor cells (NPCs). However, neurogenesis precedes gliogenesis, which normally commences at later stages of fetal telencephalic development. Astrocyte differentiation of mouse NPCs at embryonic day (E) 14.5 (relatively late gestation) is induced by activation of the transcription factor STAT3, whereas at E11.5 (mid-gestation) NPCs do not differentiate into astrocytes even when stimulated by STAT3-activating cytokines such as leukemia inhibitory factor (LIF). This can be explained in part by the fact that astrocyte-specific gene promoters are highly methylated in NPCs at E11.5, but other mechanisms are also likely to play a role. We therefore sought to identify genes involved in the inhibition of astrocyte differentiation of NPCs at midgestation. We first examined gene expression profiles in E11.5 and E14.5 NPCs, using Affymetrix GeneChip analysis, applying the Percellome method to normalize gene expression level. We then conducted in situ hybridization analysis for selected genes found to be highly expressed in NPCs at midgestation. Among these genes, we found that N-myc and high mobility group AT-hook 2 (Hmga2) were highly expressed in the E11.5 but not the E14.5 ventricular zone of mouse brain, where NPCs reside. Transduction of N-myc and Hmga2 by retroviruses into E14.5 NPCs, which normally differentiate into astrocytes in response to LIF, resulted in suppression of astrocyte differentiation. However, sustained expression of N-myc and Hmga2 in E11.5 NPCs failed to maintain the hypermethylated status of an astrocyte-specific gene promoter. Taken together, our data suggest that astrocyte differentiation of NPCs is regulated not only by DNA methylation but also by genes whose expression is controlled spatio-temporally during brain development.
