Neuronal firing and neuron-to-neuron synaptic wiring are currently widely described as orchestrated by astrocytes—elaborately ramified glial cells tiling the cortical hippocampal space into non-overlapping domains, each covering hundreds of individual dendrites thousands synapses. A key component to astrocytic signaling is dynamics cytosolic Ca 2+ which displays multiscale spatiotemporal patter...

Human dental follicle cells (DFCs) derived from wisdom teeth are precursor cells for cementoblasts. In this study, we recognized that naïve DFCs express constitutively the early neural cell marker beta-III-tubulin. Interestingly, DFCs formed beta-III-tubulin-positive neurosphere-like cell clusters (NLCCs) on low-attachment cell culture dishes in serum-replacement medium (SRM). For a detailed ex...

Amyotrophic lateral sclerosis (ALS) is a fatal neurological disease characterized by the degeneration of the motor neurons. We tested whether treatment of superoxide dismutase (SOD1)-G93A transgenic mouse, a model of ALS, with a neural stem cell subpopulation double positive for Lewis X and the chemokine receptor CXCR4 (LeX+CXCR4+) can modify the disease's progression. In vitro, after exposure ...

Von Hippel-Lindau (VHL) tumor suppressor protein is expressed in neurons of the central nervous system and plays an important role during the neuronal differentiation of central nervous system progenitor cells. To elucidate the neuronal differentiating potential of VHL protein in neuroblastoma cells, we overexpressed or inhibited VHL protein in human neuroblastoma cells (SY-SH5Y), and examined ...
