background: mesenchymal stem cells (mscs) have been recently received increasing attention for cell-based therapy, especially in regenerative medicine. however, the low survival rate of these cells restricts their therapeutic applications. it is hypothesized that autophagy might play an important role in cellular homeostasis and survival. this study aims to investigate the regenerative potentia...

background: wound healing of burned skin remains a major goal in public health. previous reports showed that the bone marrow stem cells were potent in keratinization and vascularization of full thickness skin wounds. methods: in this study, mesenchymal stem cells were derived from rat adipose tissues and characterized by flowcytometry. staining methods were used to evaluate their differentiatio...

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 ...

The LX-2 cell line has characteristics of hepatic stellate cells (HSCs), which are considered pericytes of the hepatic microcirculatory system. Recent studies have suggested that HSCs might have mesenchymal origin. We have performed an extensive characterization of the LX-2 cells and have compared their features with those of mesenchymal cells. Our data show that LX-2 cells have a phenotype res...

introduction: stromal cells having preadipocyte characteristics can be isolated from adipose tissue, propagated in vitro and induced to differentiate in vitro toward the osteogenic, adipogenic, myogenic and chondrogenic lineages when treated with established lineage-specific factors. in this research we isolated stromal cells from human adipose tissue and cultured and expanded and examined thei...

Mesenchymal stem cells (MSCs) have been studied widely for their potential to differentiate into various lineage cells including neural cells in vitro and in vivo. To investigate the influence of the developing host environment on the integration and morphological and molecular differentiation of MSCs, human bone marrow-derived mesenchymal stem cells (BM-MSCs) were transplanted into the develop...

Human-derived placental tissues have been shown in randomized clinical trials to be effective for healing chronic wounds, and have also demonstrated the ability to recruit stem cells to the wound site in vitro and in vivo. In this study, PURION(®) Processed dehydrated human amnion/chorion membrane allografts (dHACM, EpiFix(®) , MiMedx Group, Marietta, GA) were evaluated for their ability to alt...

PURPOSE Bone regeneration through distraction osteogenesis (DO) is promising but remarkably slow. To accelerate it, autologous mesenchymal stem cells have been directly injected to the distraction site in a few recent studies. Compared to direct injection, a scaffold-based method can provide earlier cell delivery with potentially better controlled cell distribution and retention. This pilot pro...

objective(s): electrospun nanofibrous mats of poly(lactic acid) (pla) and nanohydroxyapatite (nano-ha) were prepared and proliferation and differentiation of mesenchymal stem cells on the prepared nanofibers were investigated in this study. materials and methods: pla/nano-ha nanofibers were prepared by electrospinning. the effects of process parameters, such as nano-ha concentration, distance, ...
