The umbilical cord (UC) is an essential part of the placenta, contributing to foetal development by ensuring the blood flow between mother and foetus. The UC is formed within the first weeks of gestation by the enclosure of the vessels (one vein and two arteries) into a bulk of mucous connective tissue, named Wharton's jelly (WJ) and lined by the umbilical epithelium. Since their first identifi...

Three types of tissue samples--umbilical cord (UC), umbilical cord serum (CS), and maternal serum (MS)--have often been used to assess fetal exposure to chemicals. In order to know the relationship of contamination between mothers and fetuses, we measured persistent chemicals in comparable sets of the three tissue samples. Also, we analyzed the association between the chemicals in maternal and ...

Neuroinflammation has a significant role in induce of Multiple sclerosis (MS) many approaches have been used to treat MS, but none of these methods have not been able to fully improve. One of the methods can suppress inflammation and regenerate the nervous system is the use of cell therapy. Using cell therapy in pre-clinic phase can be realized, it's mechanism and potency to suppress neuroinfla...

Mesenchymal stem cells (MSCs) are known to migrate to tumor tissues and to play an important role in cancer progression. However, the effects of MSCs on tumor progression remain controversial. The purpose of the present study was to detect the effects of human umbilical cord-derived MSCs (hUC-MSCs) on the human breast cancer cell lines MDA-MB-231 and MCF-7 in vitro and the underlying mechanisms...

In recent years, identification of new sources of adult stem cells developed rapidly, pursuing to find easily available tissues, which will give rise to homogenous stem cells populations. Up to present, bone marrow-derived mesenchymal stem cells (BM-MSCs) are unanimously considered to fulfill the criteria for being used in clinical settings, but adipose stem cells, placental and umbilical cord ...

Cell-based therapy represents a promising strategy in the treatment of neurological disorders. Human umbilical cord tissue has recently been recognized as an ideal source of mesenchymal stromal cells due to accessibility, vast abundance and safety. Here, an intracerebral hemorrhage (ICH) rat model was established by injection of bacterial collagenase VII and CM-DiI labeled human umbilical cord ...

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 monocyt...

Objective: Umbilical cord Wharton’s jelly as source of mesenchymal stem cells (MSCs) can be easily obtained. In this study, MSCs were isolated from bone marrow and Wharton’s jelly and induced to differentiate into endothelial-like cells. Materials and Methods: MSCs were isolated and induced to differentiate into endothelial-like cells using vascular endothelial growth factor (VEGF). The endothe...

Human umbilical cord blood is an excellent primitive source of noncontroversial stem cells for treatment of hematologic disorders; meanwhile, new stem cell candidates in the umbilical cord (UC) tissue could provide therapeutic cells for nonhematologic disorders. We show novel in situ characterization to identify and localize a panel of some markers expressed by mesenchymal stromal cells (MSCs; ...
