human bone marrow derived mesenchymal stem cells (hbmscs) have the potential to differentiate into cells such as adipocyte, osteocyte, hepatocyte and endothelial cells. in this study, the differentiation of hbmscs into endothelial like-cells was induced in presence of vascular endothelial growth factor (vegf) and insulin-like growth factor (igf-1). the differentiated endothelial cells were exam...

Our previous report demonstrated that bovine ephemeral fever virus (BEFV)-infected cultured cells could induce caspase-dependent apoptosis. This study aims to further elucidate how BEFV activates the caspase cascade in bovine cells. BEFV replicated and induced apoptosis in Vero and Madin-Darby bovine kidney (MDBK) cells, and a kinetic study showed a higher efficiency of replication and a greate...

tumor growth is characterized by uncontrolled cell division. for centuries, silver kushta powder, composed of nano and submicro silver particles, has been used in traditional iranian and pakistani medicine for the treatment of melanoma and breast cancer. we have found that these nanocomposite particles are similar to silver nanoparticles (agnps) in size and shape and that there are so differenc...

background:the premature termination of high producer clones, which will be killed due to cell proliferation and proteins production antagonism, is one of the basic drawback in recombinant proteins technology. furtheremore, it is supposed some toxic proteins like interferon which we intended to clone and express, inhibit host cells’ proliferation. so, it is necessary to tightly control ifn-γ pr...

aromatase inhibitors have been used as a second line therapy after tamoxifen, in estrogen-receptor positive (er+) women to reduce estrogen concentration in plasma and breast tumors. it has been shown that benzofuran(phenylmethyl)imidazoles are potent aromatase inhibitors at nano-molar concentrations, about 1000 times more potent than aminoglutetimide. in this study, cytotoxic activity of some o...

BACKGROUND Early clinical trials for gene therapy of human gliomas with retroviral packaging cells (PC) have been hampered by low transduction efficacy and lack of dissemination of PC within the tumor. In the current approach, these issues have been addressed by creating a stable packaging cell line for retroviral vectors pseudotyped with glycoproteins of lymphocytic choriomeningitis virus (LCM...

Lassa virus (LASV) is a BSL-4 restricted agent. To allow study of infection by LASV under BSL-2 conditions, we generated a recombinant virus in which the LASV glycoprotein (Gp) was placed on the backbone of lymphocytic choriomeningitis virus (LCMV) Cl13 nucleoprotein, Z and polymerase genes (rLCMV Cl13/LASV Gp). The recombinant virus displayed high tropism for dendritic cells following in vitro...
