background: stem cells from human exfoliated deciduous teeth (shed) have the capability to differentiate into neural cells. neurotrophins including nerve growth factor (ngf), brain-derived neurotrophic factor (bdnf), neurotrophin-3 (nt-3), and neurotrophin-4 (nt-4) have neurogenesis, neurotrophic, or neuroprotective effects and are expressed in developing teeth. the aim of this study was to mea...

Control over spatial distributions and patterns of individual neurons their neurites provides an essential tool for studying the meaning neuronal network patterns. Moreover, complete direction control synaptic connections between cells in each is also to investigate detailed information on relationship forward feedback signaling among cells. Here, we have developed a method topographical within...

Ghrelin functions as a neuroprotective agent and saves neurons from various insults include ischemic injury. However, it remains to be elucidated whether ghrelin protects neuronal cells against ischemic injury-induced excessive autophagy. Autophagy is required for the maintenance of neural stem cell homeostasis. However, regarding autophagic cell death, it is commonly assumed that excessive aut...

objective: the neural crest is a transient structure of early vertebrate embryos that generates neural crest cells (nccs). these cells can migrate throughout the body and produce a diverse array of mature tissue types. due to the ethical and technical problems surrounding the isolation of these early human embryo cells, researchers have focused on in vitro studies to produce nccs and increase t...

Adult hippocampal neurogenesis has been implicated in cognitive and emotional processes, as well as in response to antidepressant treatment. However, little is known about how the adult stem cell lineage contributes to hippocampal structure and function and how this process is modulated by the animal's experience. Here we perform an indelible lineage analysis and report that neural stem cells c...

multiple sclerosis is an inflammatory disease of the central nervous system in which t cells experience a second phase of activation, which ultimately leads to axonal demyelination and neurological disability. the recent advances in stem cell therapies may serve as potential treatments for neurological disorders. there are broad types of stem cells such as neural, embryonic, mesenchymal and hem...

Reversible inactivation of the medial septal area results in a spatial memory impairment and selective disruption of hilar/CA3, but not CA1, location-specific discharge. The present study examined the possibility that such septal deafferentation produces effects on hippocampal function by altering physiological properties of the primary input and output structures for hippocampus, the entorhina...

based on both animal and human studies, inequality in food intake and social instability has adverse effects on the health of individuals and the community. however, it is not known whether social instability, food deprivation and food inequality affect neuronal death and premature aging in young animals. to address this question, the effects of these adverse situations, histopathological chang...

All classes of antidepressants increase hippocampal cell proliferation and neurogenesis, which contributes, in part, to the behavioral actions of these treatments. Among antidepressant treatments, electroconvulsive seizure (ECS) is the most robust stimulator of hippocampal cell proliferation and the most efficacious treatment for depression, but the cellular mechanisms underlying the actions of...
