conclusions large amounts of preclinical studies have been made of stem cells and there is an increasing interest to perform these studies within the human population but preclinical studies are insufficient; therefore, much more and efficient studies should be conducted to evaluate the efficacy and safety of stem cells. context musculoskeletal injuries may be painful, troublesome, life limitin...

background: the aim of this study was optimization of the polyfect gene delivery method of pcdna3.1 expression vector transfected with the mouse pdx-1 gene in three different kinds of mesenchymal stem cells and hepa cells as well as comparison of transfection efficiency leading to expression of the mentioned gene in the cell types used. materials and methods: rat bone marrow-derived mesenchymal...

helicobacter pylori was the main cause of gastric cancer (gc) in all over the world that results in intestinal- and diffuse-type carcinoma. infection by this bacterium remains chronic for a long time. in vitro studies have highlighted the role of stem cells in gc. h. pylori infection results in tissue injury and the adult/tissue stem cells subsequently start to replace the dead cells. the genet...

purpose: to separate and characterize orbital fat-derived stem cells (ofscs) and compare its cellular and molecular properties with those of bone marrow-derived mesenchymal stem cells (mscs) and adipose-derived stem cells (ascs). methods: stem cells from orbital fat, abdominal fat and bone marrow aspirates have been isolated. we assessed stem cell specific cell surface markers using cytometry, ...

spinal cord injury (sci) is a debilitating disease which leads to progressive functional damages. because of limited axonal regeneration in the central nervous system, there is no or little recovery expected in the patients. different cellular and molecular approaches were investigated in sci animal models. cellular transplantation of stem cells can potentially replace damaged tissue and provid...

background: stem cell therapy in small animal medicineis still in its infancy and few in vitro and in vivo research projectsregarding animal mesenchymal stem cells (mscs) have beencarried out. on the other hand, cell tracking is the first step of thecell-based therapies and is essential to recognize cell fate posttransplantation. objectives: the aim of this study was toisolate, characterize, an...

introduction : use of adipose-derived stem cells (adscs) is a suggested hypothesis to enhance the regeneration of bone defects. this technique is of particular interest since adscs are more easily accessible via a non-invasive harvesting technique compared to bone marrow stem cells (bmscs). this study sought to assess the efficacy of adsc implantation for regeneration of localized mandibular bo...

Background Bone marrow and adipose tissue are two main sources of mesenchymal stem cells (MSCs). Some of studies suggest that there are some differences in gene expression profile of MSCs-derived from various tissues. To investigate gene expression profile by qRT-PCR, an appropriate reference gene with stable expression level should be chosen for normalizing data.  This study was designed to e...

Bone tissue engineering has been one of the most promising areas of research, providing a potential clinical application to cure bone defects. Recently, various stem cells, including embryonic stem cells (ESCs), bone marrow-derived mesenchymal stem cells (BM-MSCs), umbilical cord blood-derived mesenchymal stem cells (UCB-MSCs), adipose tissue-derived stem cells (ADSCs), muscle-derived stem cell...
