Objective(s): The prognosis of osteoporosis is very poor, and it is very important to identify a biomarker for prevention of osteoporosis. In this study, we aimed to identify candidate markers in osteoporosis and to investigate the role of candidate markers in osteogenic differentiation. Materials and Methods: Using Weighted Gene Co-Expression Network analysis, we identified three hub genes mig...
Background and Aim: Obesity is now considered as one of the main risk factors of certain known diseases such as cardio-vascular diseases, non- insulin-dependent diabetes, and common cancers. Moreover, the increase of white fat tissue is known as a main factor in the obesity process, in terms of physiology and pathology. Therefore, the understanding of adipocytes differentiation processes is cru...
هر بافتی از بدن در صورت بروز اختلال، بیماری یا جراحت نیاز به جایگزینی سلولهای از دست رفته خود خواهد داشت .سلولهای بنیادین به علت دارا بودن خواص خود نوسازی(self-renewal) و نیز قابلیت(differentiation) تمایز می توانند تکثیر شوند و سلولهای جدیدی به بافت ارائه نمایند .یکی از این دسته سلولها ؛ سلولهای بنیادی خونساز (hematopoietic stem cells)می باشند که علاوه بر اینکه می توانند به سلولهای خونی تبدیل ش...
Stem cells are undifferentiated biological cells that can differentiate into more specialized cells and divide (through mitosis) to produce more stem cells (self-renew). In mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. Mesenchymal stem cells (MSCs) are ...
abstract background: sodium arsenite (sa) recently has been recommended to be used in malignancy therapy. our studies showed, sa in short and long period of treatment caused reduction of rats bone marrow mesenchymal stem cells (mscs) viability and induced caspase dependent apoptosis. the aim of this study was to investigate the effect of sa on osteogenic differentiation of mscs. methods: mscs w...
introduction: type i diabetes mellitus is caused by autoimmune destruction of the insulin-producing β-cells. a new potential method for curing the disease is transplantation of differentiated insulin- secreting cells from human embryonic stem cells. methods: human embryonic stem cell lines (royan h1) were used to produce embryoid bodies. differentiation carried out by growth factor-mediated sel...
photodynamic therapy (pdt) using 5-aminolevulinic acid (5-ala)-induced protoporphyrin ix (ppix) has been considered as a new method for treating neoplasms. however, ala-pdt is suboptimal for thick tumors. searching for new approaches, we investigated the effect of adding differentiation therapy (dt) with vitamin e succinate (ves) to pdt in human prostate ln-cap-fgc10 cancer cells in vitro . the...
the identification of multipotential mesenchymal stem cells (mscs) derived from adult human tissues such as bone marrow and connective tissues has provided exciting prospects for cell-based tissue engineering and regeneration. this review article focuses on the biology of mscs, their differentiation potentials in vitro and in vivo, and their application in tissue engineering. our current unders...
conclusions based on our findings, we conclude that the separation and reproduction of adipose tissue cells is an appropriate method for purification of mscs in animal studies. regarding the histomorphometric and flow cytometry analysis results, we demonstrated the differentiation ability of mscs in normal medium and hope to employ these cells for the regeneration of damaged bone tissues in the...
human umbilical cord matrix (hucm) is considered as a promising source of mesenchymal stem cells (mscs) due to several advantages over other tissues. the potential of neural differentiation of hucm-mscs is of great interest in the context of treating neurodegenerative diseases. in recent years, considerable efforts have been made to establish in vitro conditions for improving the differentiatio...
