Despite a comprehensive mapping of the Parkinson's disease (PD)-related mRNA and protein leucine-rich repeat kinase 2 (LRRK2) in the mammalian brain, its physiological function in healthy individuals remains enigmatic. Based on its structural features and kinase properties, LRRK2 may interact with other proteins involved in signalling pathways. Here, we(More)
Isolation and propagation of neural stem cells derived from human brain tissue uniquely enables the study of human neurogenesis in vitro. In addition, ex vivo-expanded human neural stem/precursor cells (NPCs) may offer novel therapeutic strategies. We investigated the effects of extracellular nucleotides on the proliferation and differentiation of human(More)
The efficient generation of specific brain cells in vitro may serve as a source of cells for brain repair in several devastating neurological diseases. Production of dopaminergic neurons from precursor cells for transplantation in Parkinson's disease has become a major research goal. We found that murine mesencephalic neurospheres were viable and(More)
Stem cell research offers unique opportunities for developing new medical therapies for devastating diseases and a new way to explore fundamental questions of biology. Establishing an efficient freezing protocol for neural precursor cells (NPCs) is of great importance for advances in cell-based therapies. We used fluorescence-activated cell sorter-based(More)
Oxygen tension is critical for proliferation of human and murine midbrain-derived neural precursor cells (mNPCs). Here, we conditionally inactivated the hypoxia-responsive transcription factor hypoxia-inducible factor-1alpha (HIF-1alpha) in murine NPCs to determine its role in proliferation, survival, and dopaminergic differentiation in vitro as well as(More)
Hypoxia-inducible factor-1 (HIF-1) plays an important role in neural progenitor cell (NPC) propagation and dopaminergic differentiation. In the presence of oxygen and iron, hypoxia-inducible factor 1 alpha (HIF-1alpha) is rapidly degraded via the prolyl hydroxylase (PHD)/VHL pathway. In addition to hypoxia, various non-hypoxic stimuli can stabilize(More)
Global gene expression profiling was performed using RNA from adult human hippocampus-derived neuroprogenitor cells (NPCs) and multipotent frontal cortical fetal NPCs compared with adult human mesenchymal stem cells (hMSCs) as a multipotent adult stem cell control, and adult human hippocampal tissue, to define a gene expression pattern that is specific for(More)
Tissue-specific stem cells, such as bone-marrow-derived human mesenchymal stem cells (hMSCs), are thought to be lineage restricted and therefore, could only be differentiated into cell types of the tissue of origin. Several recent studies however have suggested that these types of stem cells might be able to break barriers of germ layer commitment and(More)
In allogenic and xenogenic transplantation, adequate immunosuppression plays a major role in graft survival, especially over the long term. The effect of immunosuppressive drugs on neural stem/progenitor cell fate has not been sufficiently explored. The focus of this study is to systematically investigate the effects of the following four different(More)
Fetal human neural precursor cells (NPCs) are unique with respect to their capacity to proliferate and to preserve their potential to differentiate into neurons and glia. Human mesencephalic neural precursor cells (hmNPCs) provide a source for dopaminergic neurons. Preclinical and clinical research will benefit from reliable in vivo tracking of transplanted(More)
