Project description:Hematopoietic stem cells are both necessary and sufficient to sustain the complete blood system of vertebrates. Here we show that Nfix, a member of the nuclear factor I (Nfi) family of transcription factors, is highly expressed by hematopoietic stem and progenitor cells (HSPC) of murine adult bone marrow. Although shRNA mediated knockdown of Nfix expression in Lineage-Sca-1+c-Kit+ HSPC had no effect on in vitro cell growth or viability, Nfix-depleted HSPC displayed a significant loss of colony forming potential, as well as short- and long-term in vivo hematopoietic repopulating activity. Analysis of recipient mice 4-20 days post-transplant revealed that Nfix-depleted HSPC establish in the bone marrow but fail to persist due to increased apoptotic cell death. Gene expression profiling of Nfix-depleted HSPC reveals that loss of Nfix expression in HSPC is concomitant with a decrease in the expression of multiple genes known to be important for HSPC survival, such as Erg, Mecom, Mpl and Prdm16. These data reveal that Nfix is a novel regulator of HSPC survival post-transplantation and establish, for the first time, a role for Nfi genes in the regulation of this cellular compartment. 3 NFIX depleted samples are compared to 3 wt samples

Project description:Adult neural progenitor cells (aNPCs) are a potential autologous cell source for cell replacement in neurologic diseases such as Parkinsonâs disease or stroke or for cell-based gene therapy for neurometabolic diseases. Easy accessibility, long-term expandability and detailed characterization of NPC properties are important requisites for their future translational/clinical applications. aNPC can be isolated from different regions of the adult human brain including the accessible subcortical white matter (aNPCWM), but systematic studies comparing long-term expanded aNPCWM with aNPC from neurogenic brain regions to check for their NPC characteristics and performance are not available. Freshly isolated cells from subcortical white matter and hippocampus (aNPCHIP) expressed oligodendrocyte progenitor cell (OPC) markers such as A2B5, NG2 and OLIG2 in ~20% of cells but no neural stem cell (NSC) markers such CD133 (Prominin1), NESTIN, SOX2 or PAX6. The EGF receptor (EGFR) protein was expressed in 18% of aNPCWM and 7% of aNPCHIP, but only a small fraction of 1 cell out 694 cells from white matter and only 1 out of 1,331 hippocampal cells were able to generate neurospheres. Studies comparing subcortical aNPCWM with their hippocampal counterparts showed that both NPC types expressed mainly markers of glial origin such as NG2, A2B5 and OLIG2, and the NSC/NPC marker Nestin, but no pericyte markers. Both NPC types were able to produce fully mature neurons, astrocytes and oligodendrocytes in comparable amounts to fetal NSC. Whole transcriptome analyses finally confirmed the strong similarity of aNPCWM with aNPCHIP. Our data show that aNPCWM are multipotent NPC with long-term expandability capacity similar to NPC from hippocampus making them an easily accessible source for possible autologous NPC-based treatment strategies.

Adult human hippocampal (hip) and subcortical white matter (wm) tissue was obtained from routine epilepsy surgery procedures following informed consent of the subjects. All procedures were in accordance with the Helsinki convention and approved by the Ethical Committee of the University of Dresden (No. 47032006). All subjects underwent high-resolution magnetic resonance imaging excluding tumors and were screened for the presence of infectious disease. In all cases the neuropathological examinations did not reveal evidences for tumor formation. Gene expression Single-channel oligonucleotide microarray analysis. For the gene expression microarray analysis we used the Affimetrix U133A chips containing 22.215 probe sets representing at least 12.905 individual genes. The whole procedure was performed following the manufacturerâs standard protocol (Affimetrix, Santa Clara, CA). For the data processing, normalization was calculated with the GCRMA (GC content corrected Robust Multi-array Analysis) algorithm. fNSC: Human fetal neural stem cells, 2 biological rep aNPChip: Human adult neural progenitor cells isolated from hippocampus, 3 biological rep aNPCwm: Human adult neural progenitor cells isolated from white matter, 2 biological rep

Project description:We have characterized the transcriptome of adult rat hippocampal neural stem and progenitor cell (NSPC) cultures. The NSPCs cultures can be reversibly arrested by the quiescence-promoting signal BMP4. We provide expression data from NSPCs grown as neurospheres for 4 days in vitro in the presence of FGF2 (proliferating NSPCs) or FGF2+BMP4 (quiescent NSPCs) showing that entry into quiescence involves major changes in the transcriptional profile of the cells.

Project description:The generation of cellular identity and diversity within the developing spinal cord is critically dependent on networks of gene expression controlled by transcription factors, such as Nuclear Factor One X (NFIX). NFIX has been identified as an important factor in promoting astrocyte formation during embryonic mouse spinal cord development. To gain a more comprehensive understanding of the transcriptional landscape controlled by NFIX within the developing spinal cord, here we performed microarray analysis on E14.5 wild-type and Nfix-/- mouse spinal cords, the age at which the expression of NFIX by neural progenitor cells lining the spinal central canal is strongest.

Project description:Neural progenitor cells have the ability to give rise to neurons and glia in the embryonic, postnatal and adult brain. During development, the program regulating whether these cells divide and self-renew or exit the cell cycle and differentiate is tightly controlled, and imbalances to the normal trajectory of this process can lead to severe functional consequences. However, our understanding of the molecular regulation of these fundamental events remains limited. Moreover, processes underpinning development of the postnatal neurogenic niches within the cortex remain poorly defined. Here, we demonstrate that Nuclear factor one X (NFIX) is expressed by neural progenitor cells within the embryonic hippocampus, and that progenitor cell differentiation is delayed within Nfix(-/-) mice. Moreover, we reveal that the morphology of the dentate gyrus in postnatal Nfix(-/-) mice is abnormal, with fewer subgranular zone neural progenitor cells being generated in the absence of this transcription factor. Mechanistically, we demonstrate that the progenitor cell maintenance factor Sry-related HMG box 9 (SOX9) is upregulated in the hippocampus of Nfix(-/-) mice and demonstrate that NFIX can repress Sox9 promoter-driven transcription. Collectively, our findings demonstrate that NFIX plays a central role in hippocampal morphogenesis, regulating the formation of neuronal and glial populations within this structure.
