the wharton’s jelly of the umbilical cord is believed to be a source of mesenchymal stem cells (mscs) which can be therapeutically applied in degenerative diseases. in this study, we investigated the immunomodulatory effect of umbilical cord derived- mesenchymal stem  cells (uc-mscs) and  bone  marrow-derived-mesenchymal stem  cells (bm-mscs) on differentiation, maturation, and endocytosis of m...

Purpose: The aim is to downregulate the expression level of NS as an important factor in sustaining stem cells and certain types of cancer cells self-renewal ability in bone marrow derived mesenchymal stem cells by RNAi strategy and investigate the effects of absence of NS in these cells. Materials and Methods: Double strand NS-specific and control siRNA oligos were designed and transfected in...

Background: Mesenchymal stem cells (MSCs), also known as mesenchymal stromal cells, are considered as an important source of adult stem cells in tissue engineering and cell therapy. They are present in various tissues such as, endometrium as the supportive cells. According to anatomical position of endometrial mesenchymal stem cells that put them in neighborhood of the fetus, they m...

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 ...

Introduction: Vitamin E as a strong antioxidant plays an important role in inhibiting free radicals. Therefore, this study aimed to investigate the effect of vitamin E on the viability, morphology and osteogenic differentiation in bone marrow mesenchymal stem cells of an adult rat. Methods: The bone marrow mesenchymal stem cells were extracted using the flashing-out method. At the end of the t...
