PURPOSE Mesenchymal stem cells (MSCs) are multipotent and give rise to distinctly differentiated cells from all three germ layers. Neuronal differentiation of MSC has great potential for cellular therapy. We examined whether the cluster of mechanically made, not neurosphere, could be differentiated into neuron-like cells by growth factors, such as epidermal growth factor (EGF), hepatocyte growt...
Memory resistor or memristor is already fabricated successfully using current nano dimension technology. Based on its unique hysteresis, the amount of resistance remains constant over time, controlled by the time, the amplitude, and the polarity of the applied voltage. The unique hysteretic current-voltage characteristic in the memristor causes this element to act as a non-volatile resistive me...
background: bone marrow stromal cells (bmsc) are used as a source for cell therapy in different model for neurological disorder such as stroke and spinal cord injury. however, the transdifferentiation of bmsc into cholinergic phenotype requires more investigation. methods: bmsc were isolated from adult rats, pre-induced with β-mercaptoethanol (bme) and followed by nerve growth factor (ngf) indu...
Purpose: The aim is to downregulate the expression level of NS as an important factor in sustaining stem cells and certain types of cancer cells self-renewal ability in bone marrow derived mesenchymal stem cells by RNAi strategy and investigate the effects of absence of NS in these cells. Materials and Methods: Double strand NS-specific and control siRNA oligos were designed and transfected in...
neural stem cells (nscs) as a heterogeneous multipotent and self- renewal population are found in different areas in the developing mammalian nervous system, as well as the sub-ventricular zone (svz) and the hippocampus of the adult brain. nscs can give rise to neurons, astrocytes and oligodendrocytes. the aim of this study was to differentiate neural stem cells into noradrenergic–like cells in...
Von Hippel-Lindau tumor suppressor protein (pVHL) functions to induce neuronal differentiation of neural stem/progenitor cells (NSCs) and skin-derived precursors (SKPs). Here we identified a neuronal differentiation domain (NDD) in pVHL. Neuronal differentiation of SKPs was induced by intracellular delivery of a peptide composed of the amino-acid sequences encoded by the NDD. Neuronal different...
A primary system has been developed in which it is possible to study the production of electrically excitable neuron-like cells from a precursor population of olfactory epithelial cells. Rat nasal epithelium was dissociated and placed in culture. The initial surviving cells are flat and ciliated and contain glial fibrillary acidic protein (GFAP). After 3-5 days electrically excitable cells appe...
The aim of this study was to investigate the effects of pentylenetetrazol (PTZ) and nuclear factor κ B (NF-κB) decoy oligodeoxynucleotides (ODNs) on p38 expression in neuron-like PC12 cells. In addition, the role of NF-κB activation in the pathogenesis of epilepsy was explored. p38 expression levels in control and PTZ-treated neuron-like PC12 cells were examined using western blotting. NF-κB de...
Background: Human embryonic stem cells (hESCs) are capable of self-renewal and large-scale expansion. They also have the capacity to differentiate into a variety of cell types including liver, cardiac and neuron cells. However, it is not yet clear whether hESCs can differentiate to hemangioblasts under in-vitro conditions. Hemangioblasts are bipotential progenitors that can generate hematopoiet...
