The therapy of neural nerve injuries that involve the disruption axonal pathways or tracts has taken a new dimension with development tissue engineering techniques. When peripheral injury (PNI), spinal cord (SCI), traumatic brain (TBI), neurodegenerative disease occur, intricate architecture undergoes alterations leading to growth inhibition and loss guidance through large distance. To improve ...

neurotrauma is one of the main medical problems that affect considerable number of population especially young persons in all countries. neurotrauma not only is a serious threat for life but also creates various disabilities and consequently imposes large costs to society. following central nervous system (cns) injury, tissue damage occurs via primary and secondary mechanisms. despite many atte...

in the last century, neural stem cells are used in a lot of studies for basic and therapeutic investigations. several sources are identified for neural stem cells including embryonic, fetal and adult stem cells. although most of studies have focused in embryonic as well as fetal cells due to their capacity to generate progenies, these cells have some problems such as immunological, availability...

Objective(s): Cell therapy has provided clinical applications to the treatment of motor neuron diseases. The current obstacle in stem cell therapy is to direct differentiation of stem cells into neurons in the neurodegenerative disorders. Biomaterial scaffolds can improve cell differentiation and are widely used in translational medicine and tissue engineering. The aim...

spinal cord injury (sci) is one of the devastating conditions leading to functional and neurological deficits following road traffic accidents. to date, there is no definite treatment for repairing damaged spinal cord tissue. in this regard, cell therapy opens a new window in front of scientists by using different cells such as mesenchymal stem cells, olfactory ensheathing cells, schwann cells,...

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...

hyaline cartilage is a vascular and neural tissue with scanty chondrocytes and limited regenerative ability. after some serious injuries of the cartilage, healing process will take place through the formation of fibrocartilage structures. currently, tissue engineering and cell therapy are 2 interesting therapeutic fields dealing with regenerative medicine. in this regard, tissue regeneration ha...

background: the artificial neural networks (anns) are useful in solving nonlinear processes, without the need for mathematical models of the parameters. since the relationship between the ct numbers and material compositions is not linear, ann can be used for obtaining tissue density and composition. objective: the aim of this study is to utilize ann for determination of the composition and mas...

although spinal cord injury (sci) is one of the most common injuries after a road accident, there is no definite treatment for it. in this regard, nanotechnology has focused to retrieve damaged tissue function by designing of a biomaterial as a mimicking extracellular matrix to reduce inflammation, scar and lactate dehydrogenase, to fill the cyst and improve the graft integration, cell prolifer...
