background: umbilical cord tissue is a very rich source of mesenchymal stem cells. instead of discarding this source we are banking the tissue along with cord blood for possible future cell based applications. the cord tissue needs to be transported and stored properly in order for it to be good enough for cell isolation at a later date. in this paper we have carried out a validation study to d...

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: the definitive endoderm (de) differentiation using the undefined media and non-human feeders can cause contaminations in the generated cells for therapeutic applications. therefore, generating safer and more appropriate de cells is needed. this study compared five different methods to establish an appropriate method for inducing an efficient de differentiation from human induced plu...

background:   objective: this study presents an economical and simple co-culture system for pluripotent stem cells generation from neonatal mouse testis   materials and methods: isolated testicular cells were cultured in dmem/f12. characteristics of the isolated cells and obtained es-like cell were immune-cytochemically confirmed by examining the presence of plzf, vimentin, oct4 and nanog prote...

background: the use of stem cells is considered as an appropriate source in cell therapy and tissue engineering. differentiation of human induced pluripotent stem cells (hipscs) to hepatocyte-like cells (hlcs) on mouse embryonic fibroblasts (mefs) feeders is confronted with several problems that hinder the clinical applications of these differentiated cells for the treatment of liver injuries. ...

this paper summarizes the proceedings of a 1 day national symposium entitled “reproductive biology, stem cells biotechnology and regenerative medicine” held at shahid sadoughi university of medical sciences, yazd, iran on 3rd march 2016. here, we collected the papers that presented and discussed at this meeting by specialists that currently researched about the overlaps of the fields of reprodu...

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...

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...
