There are approximately 1 billion prediabetic people worldwide, and the global cost for diabetes mellitus (DM) is estimated to be $825 billion. In regard Type DM, transplanting a whole pancreas or its islets has gained attention of researchers in last few decades. Recent studies showed that islet transplantation (ILT) containing insulin-producing ? cells most notable advancement cure DM. Howeve...

objective: menstrual blood stromal stem cells (mbscs) share some phenotypic and functional similarities with mesenchymal stem cells (mscs). mscs are shown to inhibit either the function or generation of different immune cells, including dendritic cells (dcs). however, data regarding mbscs’ potential effects on immune system cells are elusive. here, we examine whether mbscs affect the generation...

human bone marrow derived mesenchymal stem cells (hbmscs) have the potential to differentiate into cells such as adipocyte, osteocyte, hepatocyte and endothelial cells. in this study, the differentiation of hbmscs into endothelial like-cells was induced in presence of vascular endothelial growth factor (vegf) and insulin-like growth factor (igf-1). the differentiated endothelial cells were exam...

Induced pluripotent stem (iPS) cell technology offers an unprecedented opportunity to study patient-specific disease. This biotechnology platform enables recapitulation of individualized disease signatures in a dish through differentiation of patient-derived iPS cells. Beyond disease modeling, the in vitro process of differentiation toward genuine patient tissue offers a blueprint to inform dis...
