background: several studies have demonstrated the immunosuppresive effects of mes-enchymal stem cells (mscs) in allogeneic or mitogenic interactions. cell-cell contact inhibition and secretion of suppressive soluble factors have been suggested in this re-gard. objective: to investigate if adipose derived mscs could inhibit jurkat lym-phoblastic leukemia t cell proliferation during coculture. me...

Introduction Based on previous researches, dental pulp stem cells (DPSCs) are easily accessible with limited morbidity after collection. Their embryonic origin, from neural crests, explains their multipotency. DPSCs are primarily derived from the pulp tissues of the teeth.Objective: This study was undertaken to isolate, culture, and characterize two different third molar and first premolar hum...
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: during the resent years there has been interest in using bone marrow stem cells to treat liver cirrhosis. however, there is a potential concern for malignant transformation after stem cell therapy. the aim of this study was to evaluate the development of hepatocellular carcinoma (hcc) after autologous bone marrow stem cell transplantation for liver cirrhosis. methods: all the patien...
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 n...
the aim of this study was to isolate mouse embryonic stem cells from late blastocyst stage embryos and to use them as a model system for the study of hematopoietic induction outside the embryo by coculturing of embryonic stem cells with bone marrow stromal cells. blastocyst stage embryos from pregnant nmri mice were obtained and cultured for 1-2 days in dmem medium. the inner cell masses formed...
Little is known about how neural stem cells are formed initially during development. We investigated whether a default mechanism of neural specification could regulate acquisition of neural stem cell identity directly from embryonic stem (ES) cells. ES cells cultured in defined, low-density conditions readily acquire a neural identity. We characterize a novel primitive neural stem cell as a com...
The protective effects of erythropoietin on spinal cord injury have not been well described. Here, the eukaryotic expression plasmid pcDNA3.1 human erythropoietin was transfected into rat neural stem cells cultured in vitro. A rat model of spinal cord injury was established using a free falling object. In the human erythropoietin-neural stem cells group, transfected neural stem cells were injec...
