Objective(s):In previous investigations, we have shown para-nonylphenol (p-NP) caused significant reduction of proliferation and differentiation of rat bone marrow mesenchymal stem cells (MSCs) in vitro. In this study, we first treat the rats with p-NP, then carried out the biochemical and morphological studies on MSCs. Materials and Methods: Proliferation property of cells was evaluated with t...

Objective(s): Although many researchers have confirmed induction of germ cells from bone marrow mesenchymal stem cells (BMMSCs), there are no reports that confirm spontaneous differentiation of germ cells from BMMSCs. In this study, we have evaluated the effect of adult Sertoli cell condition medium (SCCM) as a mutative factor in the induction of germ cells from BMMSCs. Materials and Methods: ...

Background: The mechanism of cadmium induced osteoporosis is not well understood, so in this study, we examined the toxicity of bone marrow mesenchymal stem cell (MSCs) following treatment of rats with CdCl2 in drinking water, to revile the effect of this chemical on differentiation potential of MSCs. Methods: At the end of third passage, MSCs were grown in the osteogenic medium for 21 days....

Background: Through combining two synthetic and natural polymers, scaffolds can be developed for tissue engineering and regenerative medicine purposes. Methods: In this work, carboxymethyl chitosan (CMC; 20%) was grafted to Polycaprolactone (PCL) nanofibers using the cold atmospheric plasma of helium. The PCL scaffolds were exposed to CAP, and functional groups were developed on the PCL surface...

In the bone marrow, there are certain populations of stem cell sources with the capacity to differentiate into several different types of cells. Ideally, cell transplants would be readily obtainable, easy to expand and bank, and capable of surviving for sufficient periods of time. Bone marrow mesenchymal stem cells (BM-MSCs) possess all of these characteristics. One of the most important benefi...

objective: mechanism of zoledronic acid on osteoblastic differentiation of mesenchymal stem cells (mscs) has not fully understood. with the knowledge of some drugs mechanism that alter methylation pattern of some genes, the present research sets out to evaluate osterix (osx) promoter methylation pattern during zoledronic acid-induced osteoblastic differentiation of mscs. materials and methods: ...

objective(s) it is believed that the mesenchymal stem cell (msc) differentiation and proliferation are the results of activation of wnt signaling pathway. on the other hand, lithium chloride is reported to be able to activate this pathway. the objective of this study was to investigate the effect of lithium on in vitro proliferation and bone differentiation of marrow-derived msc. materials and ...
