background: the present study investigated the functional maturity of oligodendrocyte derived from rat bone marrow stromal cells (bmsc). methods: the bmsc were isolated from female sprague-dawley rats and evaluated for different markers, such as fibronectin, cd106, cd90, oct-4 and cd45. transdifferentiation of olc from bmsc was obtained by exposing the bmsc to dmso and 1 µm all-trans-retinoic a...

background: bacterial superantigen staphylococcal enterotoxins (ses), has stimulated polyclonal t cells irrespective of their antigen specificity, resulted a massive release of cytokines, and suggested that they could be assigned as a candidate of new antitumor agents. recent attempts have done to specifically target superantigens towards tumors, subsequently monoclonal antibodies and tumor-rel...

background and objective: vascular endothelial growth factor (vegf) and its receptors (vegf-r1 and r2) are major regulators of angiogenesis. this study was designed to assess serum levels of vegf and vegf-r1 and their prognostic significance in newly diagnosed childhood acute leukemia. materials and methods: for this purpose, vegf and vegf-r1 were determined using enzyme linked immuno-sorbant a...
