signaling in pluripotent stem cells is a complex and dynamic process involving multiple mediators, finely tuned to balancing pluripotency and differentiation states. characterizing and modifying the necessary signaling pathways to attain desired cell types is required for stem-cell applications in various fields of regenerative medicine. these signals may help enhance the differentiation potent...

introduction: cardiac glycosides such as digoxin or digitoxin are the natural products that are traditionally used to increase cardiac contractile force in patients with heart failure and cardiac arrhythmias. it has been shown that digoxin can directly inhibit the cell proliferation and lead to cell apoptosis. present study was conducted to analyze the effect of digoxin in the cohorts of mesenc...

epilepsy as one of the most common neurological disorders affects more than 50 million people worldwide with a higher prevalence rate in low-income countries. excessive electrical discharges in neurons following neural cell damage or loss cause recurrent seizures. one of the most common and difficult to treat types of epilepsy is temporal lobe epilepsy (tle) which results from hippocampal scler...

received: 23/sep/2008, accepted: 23/nov/2008oct-4/ pou5f1/ oct-3, a pou domain family protein acts as a crucial transcription factor dur- ing embryonic development. it helps in maintenance of self renewal as well as pluripotential state of embryonic stem (es) cells. its expression starts right from 2 cell stage especially prior to 8 cell stage till the blastocyst stage where it is strongly exp...

Dedifferentiation is the transformation of cells from a given differentiated state to a less differentiated or stem cell-like state. Stem cell-related genes play important roles in dedifferentiation, which exhibits similar histone modification and DNA methylation features to stem cell maintenance. Hence, stem cell-related factors possibly synergistically function to provide a specific niche ben...

post-remission treatment in patients with acute myeloid leukemia is still controversial. one potent choice for patients with no donor available is autologous stem cell transplantation. the median follow-up period was 18 months and the median age was 26 years old. in the review of 116 recently diagnosed aml patients (except aml- m3) who underwent autologous stem cell transplantation, 72.4% of pa...

The aim of this study was to investigate the interactions between rat intestine decellularized scaffold and human adipose derived mesenchymal stem cells. Rat large intestine was dissected in fragments and decellularized by physicochemical methods. The scaffolds were loaded by human adipose derived mesenchymal stem cells expressing green fluorescent protein. Microscopic sections were prepared fr...
