introduction: we aimed at evaluating the clinical, laboratory and echocardiography effects of intracoronary administration of autologous bone marrow stem cell transplantation in different clinical entities of chronic heart failure (hf) patients.   methods: this procedure was carried out during an interventional study conducted in the cardiology department from jan 2012 to apr 2013. the hf patie...

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. ...

Neural stem cells (B1 astrocytes; NSCs) in the adult ventricular-subventricular-zone (V-SVZ) originate in the embryo. Surprisingly, recent work has shown that B1 cells remain largely quiescent. They are reactivated postnatally to function as primary progenitors for neurons destined for the olfactory bulb and some corpus callosum oligodendrocytes. The cellular and molecular properties of quiesce...

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...

The 2nd Royan Institute International Summer School was built around the topic of stem cells and grounding in the discipline of developmental biology. The meeting provided not only direct transfer of technical and intellectual information, the normal process in scientific meetings, but was also a forum for the exchange of personal ideas of science as a creative pursuit. This summer school intro...

In both human chronic lymphocytic leukemia (CLL) and the New Zealand Black (NZB) murine model of CLL, decreased levels of microRNAs miR-15a/16 play an important role in the disease. Here we investigate the effects of this microRNA on early steps of B cell development and the capacity of miR-15a-deficient hematopoietic stem cells (HSC) and B1 progenitor cells (B1P) to reproduce CLL-like phenotyp...

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...
