objective(s):transplantation quality improvement and reduction of cellular damage are important goals that are now considered by researchers. melatonin is secreted from the pineal gland and some organs such as testes. according to beneficial effects of melatonin (such as its antioxidant and antiapoptotic properties), researchers have proposed that the use of melatonin may improve transplantatio...

objective(s) bone marrow is the traditional source of human multipotent mesenchymal stem cells (mscs), but adipose tissue appears to be an alternative and more readily available source. in this study, rat adipose-derived stem cells (adscs) were induced to differentiate into schwann-like cells and compared with rat bone marrow stem cells (bmscs) for their schwann-like cells differentiation poten...

objective(s) it is believed that the mesenchymal stem cell (msc) differentiation and proliferation are the results of activation of wnt signaling pathway. on the other hand, lithium chloride is reported to be able to activate this pathway. the objective of this study was to investigate the effect of lithium on in vitro proliferation and bone differentiation of marrow-derived msc. materials and ...

background: characteristics of differentiated osteoblasts from adipose derived stem cells (adscs) in compared with isolated osteoblasts from normal bone such as calvaria are unknown. the aim of this study was determination and comparison of phenotypic characterization between differentiated osteoblasts from stem cells and calvaria osteoblasts in vitro . methods: in this study, mesenchymal stem ...

introduction: multiple sclerosis (ms) has been recognized as a common neurodegenerative disease that occurs after an auto reactive t cells against myelin antigens.  demyelination and inflammation are the main features of this disease. the anti-inflammatory and neuroprotective roles of bone marrow-derived mesenchymal stem cells (bm-mscs) have been considered as a suitable treatment against autoi...

several sources were introduced for cell therapy after neurotrauma. there are some evidences that quiescent stem cells are located in the various regions of the adult mammalian brain including cortex, hippocampus, amygdala and striatum. but more study is needed to identify the characteristics of these cells. in the present study we investigated the possibility of isolating neural stem cells fro...

in worldwide, an estimated 40 cases per 1 million people reported with new spinal cord injuries each year. people with spinal cord injuries suffer from severe physical, psychological, social and economic problems. damaged or lost cells can't be replaced when the spinal cord is injured; therefore, its function becomes disturbed permanently. despite the significant advances in the understand...

Plant regeneration at the cellular and tissue level is a unique process. Similar to animals, the stem cells in plants have properties that help stimulate and regenerate plants after injury. The unique properties of plant stem cells have been a recent area of interest and focus both in developing new cosmetics and studying how these extracts/phytohormones will influence animal skin. This special...

Somatic stem cells ensure tissue renewal along life and healing of injuries. Their safe isolation, genetic manipulation ex vivo and reinfusion in patients suffering from life threatening immune deficiencies (for example, severe combined immunodeficiency (SCID)) have demonstrated the efficacy of ex vivo gene therapy. Similarly, adult epidermal stem cells have the capacity to renew epidermis, the...
