Schwannoma is benign tumor that can occur in any part of the nerve contains a Schwann cell. It rare head and neck region characterized by common postoperative neurologic symptoms. We experienced cervical schwannoma 22-year-old young man. Except for foreign body sensation mass anterior region, there were no other complaints. A retropharyngeal was most suspected considering computed tomography, m...

Traumatic peripheral nerve injuries constitute a huge concern to public health. Nerve damage leads decrease or even loss of mobility the innervated area. Adult stem cell therapies have shown some encouraging results and been identified as promising treatment candidates for regeneration. A major obstacle that approach is securing sufficient number cells at injured site produce measurable therape...

in this review the role of cerebrospinal fluid (csf) in mammalian cerebral cortex development has been highlighted. many studies have focused on the potential role of the csf in the developmental process. in particular, the cerebral cortex develops from the germinal epithelium adjacent to the csf. csf contains proteins, growth factors and other neurotrophic factors which are important for neura...

background: considering the common origin of skin and peripheral nervous system, a tube of dermal layer of skin hypothetically can be an ideal conduit for nerve reconstruction. an experimental study performed to evaluate the nerve regeneration of efficacy into a dermal tube. methods: sixty male wistar rats were used. a 10 mm gap was produced in right sciatic nerves. in group a the autogenous ne...

Neurotrauma injuries are notoriously difficult to deal with both clinically as well experimentally, the cellular and molecular events ensuing after injury complicate neuroinflammatory processes. Spinal cord further complicated by formation of scars at sites, which can provide a physical barrier repair. The lack effective clinical therapy for spinal underscores need experimental approaches gener...

Objective- Adipose tissue is an appropriate source for isolation of cells with stem-cell–like properties.  In the present long-term study, the effects of the omental adipose-derived nucleated cells (OADNCs) fraction were compared to those of the undifferentiated cultured bone marrow stromal cells (BMSCs) on sciatic nerve regeneration. Design- Experimental in vivo study. Animals- Fift...

In hydra, nerve cells are a differentiation product of the interstitial cell, a multipotent stem cell. Nerve cell commitment was examined during head regeneration in Hydra attenuata. Within 3 h of head removal there is a 10- to 20-fold increase in nerve cell commitment in the tissue which subsequently forms the new head. Nerve cell commitment is unaltered in the remainder of the gastric region....

mouse embryonic stem cells (es) are pluripotent cell lines derived from the inner cell mass of the blastocyst. their properties include self renewal and capacity to differentiate into different cell types. neural differentiation of es cells has been achieved by several different protocols such as treating with retinoic acid and serum decreasing in culture media. the ppars (peroxisome proliferat...
