background: the aim of this research was to evaluate the effect of adipose derived stem cells on bone repair in through and through mandibular bone defects of canine. materials and methods: in this prospective comparative study, adipose-derived stem cells were isolated from subcutaneous fat of lateral thoracic area of 4 dogs. the isolated cells were cultured and expanded through 3 passages. the...

Objective(s):Some evidence showed that calcitriol has an important role in regulating growth and differentiation of mesenchymal stem cells (MSCs). However, the interaction between mesenchymal stem cells and macrophage is not clear yet.  The current study was done to investigate the in vitro effects of calcitriol on the interactions between bone marrow-derived MSCs and rat macrophages. Material...

Background: Mesenchymal stem cells have been widely considered in clinical researches because of their self-renewality and differentiation into various tissues. Nevertheless, their limited in vitro life span, which occurs only after several divisions, makes some changes in these cells, which affects all of their characteristics and remarkably reduces their application. In this study, the effect...

background: recent publications about differentiation of stem cells to germ cells have motivated researchers to make new approaches to infertility. in vitro production of germ cells improves understanding differentiation process of male and female germ cells. due to the problem of using embryonic stem cells (esc), it’s necessary the mentioned cells be replaced with some adult multi-potent stem ...

Objective(s): Studies have confirmed that microgravity, as a mechanical factor, influences both differentiation and function of mesenchymal stem cells. Here we investigated the effects of simulated microgravity on neural differentiation of human adipose-derived stem cells (ADSCs). Materials and Methods:We have used a fast rotating clinostat (clinorotation) to simulate microgravity condition. R...
