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. Isolation and propagation of multipotent NPCs. 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: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:Neural stem cells (NSCs) continuously produce new neurons within the adult mammalian hippocampus. However, this process declines with age and this decline correlates with defects in cognitive function and mood. Molecular mechanisms that activate quiescent NSCs to generate progenitor cells in vivo remain poorly understood. Here we show that adult hippocampal NSCs express VEGFR3, a key regulator of vascular and neural development, and are activated by the VEGFR3 ligand VEGF-C to enter the cell cycle and convert into progenitor cells. Conditional deletion of Vegfr3 in NSCs leads to a decline in hippocampal neurogenesis. Functionally, this is associated with increased anxiety behavior and compromised NSC activation in response to VEGF-C and physical activity. These findings establish VEGFR3 expression as a hallmark of adult mouse NSCs and demonstrate a specific requirement for VEGF-C/VEGFR signaling in NSC activation. Enhancing VEGFR3 signaling by VEGF-C may improve neurogenesis and mood during aging.
