Background & Aims: Burning provides irreparable effects on the affected patient. Several studies show that these cells may contribute to tissue regeneration whether through producing a variety of bioactive growth factors and/or by differentiation into mesoderm lineage. Several studies demonstrate that stimulated mesenchymal stem cells have more therapeutic potential than unstimulated cell ...
backgrounds: evidence is accumulating to support disruption of tissue architecture as a powerful event in tumor formation. for the past four decades, intensive cancer research with the premise of “cancer as a cell based-disease” focused on finding oncogenes or tumor suppressor genes. however, the role of the tissue architecture was neglected. three dimensional (3d) cell cultures which can recap...
Background: Pregnancy is a unique immunologic phenomenon in that despite expressing antigens with paternal origin of the embryos the interaction between maternal immune cells and fetal ones not only does not cause damage to the fetus, is necessary for fetal development . Since immune cell function is essential in the success of pregnancy and many of spontaneous abortions are associated with i...
Cells that make up the bodychr('39')s tissues are usually three-dimensional architecture, the threedimensional culture system enables cells to create natural and in vivo interactions which is an ideal environment for 3D (Three-dimensional) cell growth and issues such as exchange of similar food exchanges inside Capillary in living tissue. In tissue engineering discussion, cell scaffolding is hi...
cell therapy is known as one of the most promising curative interventions in the spinal cord injury (sci). selection of an appropriate route to transplant the stem cells is very important. principally, four different injection routes have been used in animal experiments. 1. intramedullary route: this route is known as a classic method for transplantation of stem cells. in this method, the stem ...
Background: Betatrophin known as new therapeutic target of pancreases tissue. The aim of this study was to investigate the effect of endurance training program on betatrophin serum concentrations and pathological changes of pancreas tissue in diabetic rats. Material and Methods: Male wistar rats (N=24) divided in 3 group include healthy control, diabetic control and endurance training. After ...
introduction: cell culture is a process in which the cells ware isolated from original tissue, dispersed in liquid media and then placed in culture plate where the cells adhere together and propagate. today, this method is used for assessment of cell toxicity, its mechanisms and effect of different compounds on intracellular components. methods: clonogenic assay was used for assessment of cell ...
traumatic brain injury (tbi) is a common reason of brain tissue loss as a result of tumors, accidents, and surgeries. renewal of the brain parenchyma is restricted by many reasons such as inimical substances produced as the result of trauma and also inflammatory responses. a strong cascade of inflammatory responses begins as a result of tbi which include recalling peripheral leukocytes into the...
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...
