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...

introduction: failure of human body tissue and organs is believed to be one of the most important health problems all over the world. the great challenge for tissue engineers is to optimize suitable systems to separate, proliferate and differentiate the cells so that they can set out to create tissue by a harmonic 3-d growth. therefore, the tissue engineers must provide an environment like the ...

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...

introduction: various neuroregenerative procedures have been recently employed along with neurorehabilitation programs to promote neurological function after spinal cord injury (sci), and recently most of them have focused on the acute stage of spinal cord injury. in this report, we present a case of acute sci treated with neuroprotective treatments in conjunction with conventional rehabilitati...

UNLABELLED Background In vitro proliferative and differentiation potential of mesenchymal stromal cells generated from CD271(+) bone marrow mononuclear cells (CD271-mesenchymal stromal cells) has been demonstrated in several earlier and recent reports. In the present study we focused, in addition to proliferative and differentiation potential, on in vitro and in vivo immunosuppressive and lymph...

BACKGROUND Epidermal growth factor receptor (EGFR) plays a pivotal role in the pathophysiology of esophageal squamous cell carcinoma (ESCC). However, the clinical effects of EGFR inhibitors on ESCC are controversial. This study sought to identify the factors determining the therapeutic efficacy of EGFR inhibitors in ESCC cells. METHODS Immortalized-human esophageal epithelial cells (EPC2-hTER...

Undifferentiated mesenchymal cells were isolated from mouse embryonic lungs and plated at subconfluent and confluent densities. During the first 5 hours in culture, all the cells were negative for smooth muscle markers. After 24 hours in culture, the mesenchymal cells that spread synthesized smooth muscle alpha-actin, muscle myosin, desmin and SM22 in levels comparable to those of mature smooth...

Ascidian larvae develop mesenchyme cells in their trunk. A fibroblast growth factor (FGF9/16/20) is essential and sufficient for induction of the mesenchyme in Ciona savignyi. We have identified two basic helix-loop-helix (bHLH) genes named Twist-like1 and Twist-like2 as downstream factors of this FGF. These two genes are phylogenetically closely related to each other, and were expressed specif...

The development of neuroprotective strategies to attenuate retinal ganglion cell death could lead to novel therapies for chronic optic neuropathies such as glaucoma. Intravitreal transplantation of mesenchymal stem cells slows retinal ganglion cell death in models of optic nerve injury, but the mechanism of action remains unclear. Here we characterized the neuroprotective effects of mesenchymal...

Hemopoietic system derived progenitor cells with mesenchymal features have been identified including CD14(+) monocyte-derived progenitors. However, it is unclear whether there are mesenchyme derived progenitors with hematopoietic potential. Herein, we identified a novel CD14(-) cell-derived population with both mesenchymal and hematopoietic features in rat peripheral blood, and this cell popula...
