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...
PURPOSE The evidence is increasing that cancer stem cells (CSCs) expressing embryonic and neuronal stem cell markers are present in human retinoblastoma (Rb). This study was conducted to determine whether stem-like cancer cells (SLCCs) in Rb express retinal stem cell-related genes and whether SLCCs can directly differentiate into retinal neurons. METHODS The cancer stem cell characteristics i...
In the recent decade, liver diseases with high mortality rate have became one of the major health problems worldwide. Liver transplantation is the most effective and the standard treatment for decompensated liver disease, but, shortage of available organs and inaccuracy in modeling of the liver diseases are the most limiting issues in treatment. Regenerative medicine and cell based therapy str...
There is an increasing evidence supporting the cancer stem cell hypothesis. Normal stem cells in the adult organism are responsible for tissue renewal and repair of aged or damaged tissue. A substantial characteristic of stem cells is their ability for self-renewal without loss of proliferation capacity with each cell division. The stem cells are immortal, and rather resistant to action of drug...
Conventional chemotherapy is the main treatment for cancer and benefits patients in the form of decreased relapse and metastasis and longer overall survival. However, as the target therapy drugs and delivery systems are not wholly precise, it also results in quite a few side effects, and is less efficient in many cancers due to the spared cancer stem cells, which are considered the reason for c...
Both stem cells and cancer cells are thought to be capable of unlimited proliferation. Moreover, a small number of cancer cells express stem cell markers, including CD133 and ATP-binding cassette transporters, by which the cells can pump out specific fluorescence dyes, such as Hoechst33342, as well as anti-cancer drugs, suggesting that either cancer cells resemble stem cells or cancers contain ...
Cancer is, in essence, a stem cell disease. The main biological cause of cancer is that stem cells acquire DNA alterations during cell division. The more stem cell divisions a tissue accumulates over a lifetime, the higher is the risk of cancer in that tissue. This explains why cancer is diagnosed millions of times more often in some tissues than in others, and why cancer incidence increases so...
Purpose:Because chemoradiotherapy selectively targets proliferating cancer cells, quiescent cancer stem– like cells are resistant. Mobilization of the cell cycle in quiescent leukemia stem cells sensitizes them to cell death signals. However, it is unclear that mobilization of the cell cycle can eliminate quiescent cancer stem– like cells in solid cancers. Thus, we explored the use of a genetic...
