The cytoskeletal regulators that mediate the change in the neuronal cytoskeletal machinery from one that promotes oriented motility to one that facilitates differentiation at the appropriate locations in the developing neocortex remain unknown. We found that Nck-associated protein 1 (Nap1), an adaptor protein thought to modulate actin nucleation, is selectively expressed in the developing corti...

In this study we present the use of elastic macroporous cryogels for differentiation and transplantation mature neurons. We develop a coating suitable long-term neuronal culture, including stem cell differentiation, by covalent immobilization neural adhesion proteins. context therapy Parkinson's disease, show compatibility with established dopaminergic both immortalized mesencephalic progenitor...

Introduction: To evaluate the cAMP -mediated IBMX (3-IsoButyle -1-Methyl Xanthin) and db-cAMP (dibutyryl cAMP) effects on differentiation of human Embryonic Stem Cells (hESCs) into nerve cells were the objectives of this study. Methods: We have used Royan H1 hESC- derived embryoid bodies with four treatment groups: six days treatment with IBMX (5×10 -4M) and db-cAMP (10 -9M) (referred to as...

Background and Objective: Biomaterials and nanomaterials have generated a great opportunity in regenerative medicine. Neurological disorders can result in permanent and severe derangement in motor and sensory functions. This study was conducted to examine the effects of selenium nanoparticles (Se NPs) as a chemical inducer for differentiation of PC12 cells into sympathetic-like neurons characte...

Insufficient endogenous neurotrophin supply contributes to neurodegeneration. Meanwhile, neuronal injuries are also attributed to oxidative stress upon toxin exposure. Thus, reconstruction neurite extension and antioxidative stress are the potential strategies for ameliorating neuronal injuries. However, there is no well-defined therapeutic developed in this regard. In search of such therapeuti...

Metabolism and differentiation of cultured cells are influenced by changes in cellular morphology. In this study, we investigated the differences cell proliferation neuronal NT2 monolayer (2D) spheroid (3D) cultures. culture, adhered extended on a tissue culture plate. For fabricated microwell chip comprising 195 circular microwells (600 ìm diameter) cutture plate, surface was modified with pol...

background and aims:in neurodegenerative disorders,oxidative stress mediated by reactive oxygen species is strongly associated with increased neuronal damages which can lead to apoptosis. pro-apoptotic and anti-apoptotic gene expressions are changed during the cell differentiation that affect cell viability and differentiation. therefore, this study was conducted to determine the effects of hyd...

Repressor element 1 (RE1)-silencing transcription factor (REST)/neuron-restrictive silencer factor (NRSF) can repress several terminal neuronal differentiation genes by binding to a specific DNA sequence (RE1/neuron-restrictive silencer element [NRSE]) present in their regulatory regions. REST-VP16 binds to the same RE1/NRSE, but activates these REST/NRSF target genes. However, it is unclear wh...
