there are two main methods for preparing the puramatrix (pm) as a three-dimensional (3-d) scaffold for supporting the cells including surface plating and encapsulation. in the surface-plating procedure, the scaffold is created by adding an ionic agent such as medium to pm. after adjusting the ph by changing the medium, cells are seeded on top of the scaffold. in the encapsulation method, pm and...
objective: nowadays, as the field of neural tissue engineering advances, the fabrication and application of combined structures open a new window of research for the regeneration of nervous system injuries. in this study, chitosan/poly(vinyl alcohol)-carbon nanotube nanocomposites has been exploited as scaffolds. materials and methods: electrospinning was used to fabricate chitosan/poly(vinyl ...
one of the main problems following road accidents is brain injury after which death and disability in the most active population occurs. considering the fact that there is no definite clinical treatment for repair of damaged brain tissue, the present study examined the effects of autologous adult neural stem/progenitor cells (ns/pcs) seeded in a nanoscaffold named puramatrix in acute brain inju...
the incidence of traumatic brain injury (tbi) are annually increasing, developed tissue engineering methods could represent the definite remedies for patients with strongly injured central nervous system and have a great effect in the public healthcare cost. the current clinical treatments in tbi display several limitations. furthermore, several therapies, coming from neural tissue engineering ...
Background: This article reviews experimental and clinical studies in which neural injuries repaired with bone marrow stromal cells. History: Bone marrow contains two kinds of stem cells: hematopoietic and nonhematopoietic (stromal) stem cell. In vitro studies indicate that bone marrow stromal cells have the capacity of differentiation into other cells (such as neural cell) under treatment wit...
the cellular therapy and nerve tissue engineering will probably become a major therapeutic strategy for promoting axonal growth through injured area in central nervous system and peripheral nervous system in the coming years. the stem cell carrier scaffolds in nerve tissue engineering resulted in strong survival of cells and suitable differentiation into neural cells, so this pathway should be ...

The stem cell carrier scaffolds in nerve tissue engineering resulted in strong survival of cells and suitable differentiation into n...
introduction: adult stem cells are the group of cells which conserve their nature in tissues and organs among other cells. in recent years, the researchers reported the existence of stem cells on the bulge of hair follicles near to the smooth muscle. it is possible to differentiate these stem cells to neural cells by induction of shh, fgf, and ra factors. because of existence of these factors i...
introduction: the native inability of nervous system to regenerate, encourage researchers to consider neural tissue engineering as a potential treatment for spinal cord injuries. considering the suitable characteristics of induced pluripotent stem cells (ipscs) for tissue regeneration applications, in this study we investigated the adhesion, viability and proliferation of neural progenitors (de...
cerebral coenurosis is the intermediary larval stage of taenia multiceps , which affects intermediate hosts, particularly sheep and goats. in this report, gross and microscopic features of three scarce natural coenurosis cases, a oneyear-old ram and two lambs of 7 month old from a flock are explained. atnecropsy, numerous small cysts measuring 5 to 10 mm in diameter were observed on both cerebr...
