Studies on hematopoiesis have focused on the function and composition of human bone marrow stroma. Stroma function gives hematopoietic stem cells the microenvironment appropriate for self-renewal and/or prompt differentiation into hematopoietic progenitor cells, then into terminal specialized cells. Human bone marrow stroma has been dissected into hematopoietic and nonhematopoietic components. ...
today, stem cell transplantation is a hot topic in scientific circles as a novel therapeutic approach to repair the structure and function of central nervous system. the safe and neuroprotective effects of cell therapy in models and traumatic brain injury patients were evaluated in many experimental and clinical studies in recent decade and somewhat promising results were provided to the scient...
dental pulp stem cells (dpscs) can be found within the cell rich zone of dental pulp. these stem cells, under specific stimuli, differentiate into many cell types which have wide therapeutic applications. the dental stem cells are derived from both deciduous and permanent teeth. the viable dental stem cells are very simple to collect, without any mortality and morbidity. dental pulp stem cell...
Purpose: The aim is to downregulate the expression level of NS as an important factor in sustaining stem cells and certain types of cancer cells self-renewal ability in bone marrow derived mesenchymal stem cells by RNAi strategy and investigate the effects of absence of NS in these cells. Materials and Methods: Double strand NS-specific and control siRNA oligos were designed and transfected in...
Introduction: Vitamin E as a strong antioxidant plays an important role in inhibiting free radicals. Therefore, this study aimed to investigate the effect of vitamin E on the viability, morphology and osteogenic differentiation in bone marrow mesenchymal stem cells of an adult rat. Methods: The bone marrow mesenchymal stem cells were extracted using the flashing-out method. At the end of the t...
Background & Aims: Stem cells are undifferentiated cells and are found in different tissues. These cells have capacity of self-renewal and differentiation into other lineages. Granulosa cells (GCs) are the multipotent stem cells. In the present research we evaluated the differentiation potential of GCs into keratinocytes. Material & Methods: GCs were cultured after enzymatic isolation from ova...
Objective(s): Umbilical cord blood is a good source of the mesenchymal stem cells that can be banked, expanded and used in regenerative medicine. The objective of this study was to test whether amniotic membrane extract, as a rich source of growth factors such as basic-fibroblast growth factor, can promote the proliferation potential of the umbilical cord mesenchymal stem cells. Materials and ...
background isolation of adipose tissue mesenchymal stem cells (mscs) with current enzymatic methods has some limitations. for example, it is costly and time-consuming and results in a heterogeneous cell population that making compromise proliferation and differentiation of mscs. also, it is accompanied with the increased risk of culture contaminations because of several handling steps.in this ...
objective: allogeneic transplantation with umbilical cord blood (ucb) in adult recipients is limited mainly by a low cd34+ cell dose. to overcome this shortcoming, human placenta as a novel source of human mesenchymal progenitor cell (mpc)- unrestricted somatic stem cells (ussc)- was incorporated in an attempt to expand cd34+ cells from ucb. to provide a similar environment in vitro, we coated ...
objective(s) mesenchymal stem cells (mscs) are nonhematopoietic stromal cells that are capable of differentiating into and contribute to the regeneration of mesenchymal tissues. human mesenchymal stem cells (hmscs) are ideal targets in cell transplantation and tissue engineering. enhanced green fluorescent protein (egfp) has been an important reporter gene for gene therapy. the aim of this stud...
