stem cells are undifferentiated cells with the ability of proliferation, regeneration, conversion to differentiated cells and producing various tissues. stem cells are divided into two categories of embryonic and adult. in another categorization stem cells are divided to totipotent, multipotent and unipotent cells. so far usage of stem cells in treatment of various blood diseases has been studi...

Stem cells isolated from human exfoliated deciduous teeth (SHEDs) are multipotent mesenchymal stem cells that are isolated from dental pulp tissues. These cells have a high proliferative capacity, multipotential ability, immunomodulatory function, and minimal risk of oncogenesis. Recent studies have shown that SHEDs are a feasible cell source for cell therapy and regenerative medicine.

neurotrauma is one of the main medical problems that affect considerable number of population especially young persons in all countries. neurotrauma not only is a serious threat for life but also creates various disabilities and consequently imposes large costs to society. following central nervous system (cns) injury, tissue damage occurs via primary and secondary mechanisms. despite many atte...

Neurodegenerative diseases are the hereditary and sporadic diseases which are characterized by progressive neuronal loss of the nervous system and are emerging as the leading cause of death, disabilities, and a socioeconomic burden due to an increase in life expectancy. There are many neurodegenerative diseases including Alzheimer’s disease, Parkinson’s, disease, amyotrophic lateral...

background nowadays using the stem cells has opened a new horizon in the medical science and is indeed a practical and non-invasive method for treating refractory diseases such as leukemias , lymphomas, blood disorders and so on. nonetheless, proper and sustainable uses of such powerful cells undoubtedly need to be as per certain ethical principles. of the existing challenges in using stem cell...

background:   objective: this study presents an economical and simple co-culture system for pluripotent stem cells generation from neonatal mouse testis   materials and methods: isolated testicular cells were cultured in dmem/f12. characteristics of the isolated cells and obtained es-like cell were immune-cytochemically confirmed by examining the presence of plzf, vimentin, oct4 and nanog prote...

Autoimmune diseases have been described as an interesting and poorly understood group of disorders. There are many challenges in the respective scientific societies concerning the nature, causes and the therapeutic approaches of these diseases. In accordance with the evidences the nature and etiology of these disorders is multifactorial and complex but the clearest definition could be expressed...
