stem cells are of great interest for regenerating disturbed tissues and organs. these cells are commonly isolated from the bone marrow, but there has been interest in other tissues in the recent years. in this study, we evaluated the possibility of isolation of stem cells from oral connective tissue and investigated their characteristics.in this experimental study, sampling from the bone marrow...
two basic and clinical researches accomplished during the recent years on embryonic and adult stem cells constituted a mutation in regenerative therapy. these cells can be used for treating some degenerative diseases. between them, age-related functional defects, hematopoietic and immune system disorders, heart failures, chronic liver injuries, diabetes, parkinson’s and alzheimer’s diseases, ar...
background: because of the ability of proliferation, regeneration, conversion to differentiated cells and tissue producing, stem cell therapy has important clinical implications for treatment of different diseases. in this chapter we discuss different kinds of stem cells that have been used in treatment of neurologic diseases, gastrointestinal diseases, heart diseases, bone disease, kidney dise...
objective(s): osteoarthritis is one of the most common diseases in middle-aged population in the world. cartilage tissue engineering (te) has been presented as an effort to introduce the best combination of cells, biomaterial scaffolds and stimulating growth factors to produce a cartilage tissue similar to the natural articular cartilage. in this study, the chondrogenic potential of adipose der...
introduction: doxorubicin is frequently used for treatment of several types of cancer. doxorubicin cardiac toxicity has limited the use of this drug. corticosteroids may prevent doxorubicin induced cardiotoxicity. therefore the aim of this study was to evaluate mouse embryonic stem cells derived cardiomyocytes as a model to evaluate the effect of doxorubicin and dexamethasone. methods: mouse em...
In Arabidopsis thaliana, besides several key transcription factors and chromatin modifiers, phytohormones auxin and cytokinin play pivotal role in shoot and root meristem maintenance, and lateral root (LR) development. Sirtinol, a chemical inhibitor of Sir2 proteins, is known to promote some auxin induced phenotypes in Arabidopsis. However, its effect on plant stem cell maintenance or organ for...
Much effort is being invested in defining the intrinsic and extrinsic factors that control stem cell maintenance and proliferation. Recent studies have identified a signaling hierarchy involved in coordinating the proliferation of germ line and somatic stem cells in the Drosophila ovary.
In recent years, considerable advances have been made in the field of regenerative medicine. Unlikeembryonic stem cells, which pose the problems of ethical concerns and cause severe immunological reactions as well as neoplasma formation after transplantation, umbilical cord blood is a primitive source ofmesenchymal stem cells that covers the benefits of both embryonic and adult stem cells. It h...
Introduction & Objective: Stem cells are determined by their unique features. One of them is high proliferation ability and the other is potency of differentiation to various tissues. The results of new works in various countries around the world including Iran show the growing momentum of works on stem cell therapy. Working with stem cells from different origins including the cells originate...
