introduction: during the last decade, advances in tissue engineering and stem cell-based tooth regeneration have provided realistic and attractive means of replacing lost or damaged teeth. the first adult stem cells isolated from dental tissues were dental pulp stem cells (dpscs). when transplanted with hydroxyl apatite/tri calcium phosphate (ha/tcp) powder, they formed a dentin-like structure ...

Scorpion venom toxicity is of major concern due to its influence on human activities and public health. We investigated the in-vitro process of cell death caused by two Iranian scorpions Odontobuthus doriae and Bothutus salceyi venom on human cell lines. The aim of this study was to provide further information about triggering cell death and suggestion of methods for the elimination of unwanted...

Blood Brain Barrier (BBB) is a specialized non fenestrate barrier that formation by the endothelial cells and controls the transportation of the cells and molecules in to the brain. Reducing in function of BBB is one of disruptions in neurological diseases like multiple sclerosis. Endothelial progenitor cell (EPC) help to the BBB to control the diapedesis of inflammatory cells & molecules in to...
