human mesenchymal stem cells (hmscs), which also called mesenchymal stromal cells, are multipotent stem cell. human mscs typically are positive for the surface markers cd44, cd73, cd90, cd105, cd106, and also negative for hematopoietic markers cd34 and cd45.these cells can be isolated from postnatal bone marrow, adipose tissue, placenta, and scalp tissue, as well as from various fetal tissues. ...

in this present study, we examined the differentiation potential of human bone marrow derived mesenchymal stem cells (hbmscs) into hepatocytes on a three-dimentional (3d) nanofibrous scaffold formed by poly (ε-caprolactone) (pcl), collagen and polyethersulfone (pes). the nanofiber was prepared by the electrospining technique. hbmscs were isolated using combining gradient density centrifugation ...

Differentiation of derived from in vitro-incubated adult human mesenchymal stem cells (MSCs), isolated bone marrow, cartilage and adipose tissue, respectively, by application appropriate incubation conditions, to osteoclasts, was investigated proved. The current results show the importance changes mitochondrial dynamics about differentiation male germ (spermatogonia) mature functional activity ...

The feasibility of isolating and manipulating mesenchymal stem cells (MSCs) from human patients provides hope for curing numerous disease and disorders. Recent phenotypic analysis showed heterogeneity of MSCs. A nestin progenitor cell is a subpopulation within MSCs which plays a role in pancreas regeneration during embryogenesis. This study aimed to separate nestin (+) cells from human bone mar...

Retinoid-storing hepatic stellate cells (HSCs) have recently been described as a liver-resident mesenchymal stem cell (MSC) population; however, it is not clear whether these cells contribute to liver regeneration or serve as a progenitor cell population with hepatobiliary characteristics. Here, we purified HSCs with retinoid-dependent fluorescence-activated cell sorting from eGFP-expressing ra...

mesenchymal stem cells can be obtained from deferent tissues like adipose tissue, umbilical cord, placenta, skin, bone marrow, etc. these cells have regulatory effects on all types of immune cells such as dendritic cell, natural killers and lymphocytes. mesenchymal stem cells induce inhibitory phenotypes of antigen presenting cells (apcs) following their activity. they also change t cells pheno...

purpose : our aim was to isolate mesenchymal stem cells (mscs) from mouse umbilical cord and culture them with vitreous body to investigate their capacity to differentiate into lens fiber cells, crystallins are expressed. methods : wharton's jelly is the appropriate source of mscs. after isolation, the cells were cultured and alkaline phosphatase detection kit was used for staining undiffe...

conclusions taken together, the combination of chemical and growth factors in the two-step induction protocol may improve the efficiency of msc differentiation into neural progenitor cells, and may be a new method for the easy and fast application of mscs in regenerative medicine in the future. results the results of real-time pcr showed that the expression of the gfap, mbp, and map-2 genes aft...

background: mesenchymal stem cells (mscs) are undifferentiated cells that can differentiate and divide to other cell types. transplantation of these cells to the different organs is used for curing various diseases. objective: the aim of this research was whether mscs transplantation could treat the sterile testes. materials and methods: in this experimental study, donor mscs were isolated from...

objective: allogeneic transplantation with umbilical cord blood (ucb) in adult recipients is limited mainly by a low cd34+ cell dose. to overcome this shortcoming, human placenta as a novel source of human mesenchymal progenitor cell (mpc)- unrestricted somatic stem cells (ussc)- was incorporated in an attempt to expand cd34+ cells from ucb. to provide a similar environment in vitro, we coated ...
