Numerous transcriptional regulators of neurogenesis have been identified in the developing and adult brain, but how neurogenic fate is programmed at the epigenetic level remains poorly defined. Here, we report that the transcription factor Pax6 directly interacts with the Brg1-containing BAF complex in adult neural progenitors. Deletion of either Brg1 or(More)
Neural stem cells have been documented in both the developing and the mature adult CNSs of mammals. This cell population holds a considerable promise for therapeutical applications in a wide array of CNS diseases. Therefore, universally applicable strategies for the purification of this population to further its cell biological characterization are sought.(More)
Although the local environment is known to regulate neural stem cell (NSC) maintenance in the central nervous system, little is known about the molecular identity of the signals involved. Chondroitin sulfate proteoglycans (CSPGs) are enriched in the growth environment of NSCs both during development and in the adult NSC niche. In order to gather insight(More)
CNS lesions stimulate adult neurogenic niches. Endogenous neural stem/progenitor cells represent a potential resource for CNS regeneration. Here, we investigate the response to unilateral focal laser-lesions applied to the visual cortex of juvenile rats. Within 3 days post-lesion, an ipsilateral increase of actively cycling cells was observed in cortical(More)
Y-P30, the 30 amino acid N-terminal peptide of the dermcidin gene, has been found to promote neuronal survival and differentiation. Its early presence in development and import to the fetal brain led to the hypothesis that Y-P30 has an influence on proliferation, differentiation and migration. Neurospheres derived from neural stem cells isolated from E13(More)
Here we describe the expression pattern of a previously unknown mouse gene mPet-1. The isolated cDNA codes for an ETS-domain transcription factor of 237 amino acids in length, which is localized to the nucleus. mPet-1 is a member of the winged helix transcription factor gene family like its rat homologue Pet-1 and the human homologue FEV. The start ATG of(More)
Here, we present mechanisms for the inhibition of oligodendendrocyte precursor cell (OPC) differentiation, a biological function of neural extracellular matrix (ECM). The differentiation of oligodendrocytes is orchestrated by a complex set of stimuli. In the present study, we investigated the signaling pathway elicited by the ECM glycoprotein tenascin C(More)
Oligodendrocytes are the myelinating cells of the central nervous system. They differentiate from oligodendrocyte precursor cells through several intermediate states that can be followed by characteristic morphological changes and the expression of marker molecules. However, most oligodendrocyte lineage markers demarcate either the precursor or the(More)
Cells of the central nervous system are notoriously difficult to transfect. This is not only true for neurons and glial cells but also for dividing neural stem and progenitor cells (NSCs). About ten years ago a major advance was provided by introduction of the nucleofection technology that allowed for transfection of approximately half of the exposed NSCs.(More)
