background: the ultrastructural analysis of cultured follicles could direct us to understand subcellular changes during in vitro culture. objective: this study was done to verify the ultrastructural characteristics of in vitro cultured mouse isolated preantral follicles in co-culture system in the presence and absence of leukemia inhibitory factor (lif) materials and methods: mechanically isola...

In recent years there has been an explosion in the rate of acquisition of biomedical data. Advances in molecular genetics technologies, such as DNA microarrays allow us for the first time to obtain a "global" view of the cell. It has great potential to provide accurate medical diagnosis, help find the right treatment and cure for many diseases. It is still unknown why one person got the leukemi...

Background: Several studies have shown that leukemia inhibitory factor (LIF) is one of the most important cytokinesparticipating in the process of embryo implantation and pregnancy, while, the role of this factor on vascular endothelialfactor-A (VEGF-A), as one of the most important angiogenic factor, has not been fully investigated yet. The aimof this study was to evaluate th...
