Objective(s): Biocompatibility of dental biomaterials plays a critical role in regeneration of dental stem cells. The aim of present study was to evaluate the effects of novel biomaterials of TheraCal-LC (TheraCal; Bisco), Angelus mineral trioxide aggregate (MTA; Angelus), calcium-enriched mixture (CEM; BioniqueDent), and Biodentine (Septodont) on viability of human de...
introduction: in this study, the effect of para-nonylphenol as an environmental pollutant on viability, morphology and proliferation of bone marrow mesenchymal stem cells was investigated. methods: bone marrow mesenchymal stem cells of rat were treated with the 0.5, 1, 2.5, 3.5 and 5 μm of paranonylphenol for a period of 21 days, then the viability of the cells were estimated using trypan blue ...
Background and Aims: Previous studies have shown that adipose-derived mesenchymal stem/ stromal cells are one of the sources of mesenchymal stem cells (MSCs) with the capacity to differentiate into various mesodermal cell lineages. MSCs with cytokines secretion capability, which contributes to repair damaged tissues have gained wide credence for future cell-based therapeutic applications. In th...
Introduction & Objective: Stem cells are determined by their unique features. One of them is high proliferation ability and the other is potency of differentiation to various tissues. The results of new works in various countries around the world including Iran show the growing momentum of works on stem cell therapy. Working with stem cells from different origins including the cells originate...
Background and Aim: Artificial gamete production from stem cells is a novel strategy for treatment of infertility. Among various stem cell sources, embryonic stem cells (ESC) can be considered as an appropriate source for in vitro formation of germ cells. In this study we evaluated the effect of BMP4 on proliferation and differentiation of mouse embryonic stem cells into primordial germ cells (...

objective: the properties of self-renewal and divisionin spermatogonial stem cells (sscs) support spermatogenesis. there are a number of reported methods for in vitro ssc culture systems. the development of a culture system that effectively supports isolation and self-renewal ofgermline stem cells (gscs) is of tremendous benefit for clinical trials, experimental research andas potential treatme...
background: stem cell factor (scf) is a transcriptional factor which plays crucial roles in normal proliferation, differentiation and survival in a range of stem cells. objective: the aim of the present study was to examine the proliferation effect of different concentrations of scf on expansion of human endometrial cd146+ cells. materials and methods: in this experimental study, total populati...
Purpose: Differentiation of mouse embryonic stem cells into Insulin secreting endocrine cells. Materials and Methods: In this study, Royan B1 mouse embryonic stem cell (derived from C57BL/6 mouse) were used. In directed differentiation method, embryonicstem cells after embryoid bodies formation were differentiated into insulin secreting cells. Nestin positive cells were obtained after culture ...
introduction: nowadays, spermatogonial stem cells (sscs) cultivation has been used by many researchers as an effective tool for infertility treatments. oxidative conditions can be effective on cell proliferation and differentiation of these cells. so, the aim of this study was to establish oxidative stress model for antioxidant activity of some drugs investigation during sscs in vitro culture. ...
