Stem cell research has greatly contributed to the field of oncology with the identification and isolation of cancer stem cells from a variety of tumors. The discovery of rare subpopulations of cancer stem cells has indeed entirely changed the focus of cancer research. Normal adult stem cells and cancer stem cells can both self-renew and undergo a differentiation program that, in turn, gives ris...

cancer stem cells (csc) are the tumor-associated cells existed within tumors or hematological cancers which share characteristics similar to normal stem cells. the common characteristics of a normal stem cell and a csc are their differentiation capacity and self-renewal in tumors. the expression pattern of csc markers differs depending on the type and location of cancers. cd molecules are proba...

Eradication of cancer stem cells to abrogate tumor growth is a new treatment modality. However, like normal cells cancer cells show plasticity. Differentiated tumor stem cells can acquire stem cell properties when they gain access to the stem cell niche. This indicates that eradicating of stem cells (emptying of the niche) alone will not lead to eradication of the tumor. Treatment should be dir...

Recent evidence suggests that most malignancies are driven by "cancer stem cells" sharing the signature characteristics of adult stem cells: the ability to self renew and to differentiate. Furthermore these cells are thought to be quiescent, infrequently dividing cells with a natural resistance to chemotherapeutic agents. These studies theorize that therapies, which effectively treat the majori...

Cancer stem cells (CSCs) have been defined as cells within tumor that possess the capacity to self-renew and to cause the heterogeneous lineages of cancer cells that comprise the tumor. They have been identified in blood, breast, brain, colon, melanoma, pancreatic, prostate, ovarian, lung cancers and so on. It is often considered to be associated with chemo-resistance and radio-resistance that ...

The term ''oxidative stress" refers to a cell's state characterized by excessive production of reactive oxygen species (ROS) and oxidative stress is one of the most important regulatory mechanisms for stem, cancer, and cancer stem cells. The concept of cancer stem cells arose from observations of similarities between the self-renewal mechanism of stem cells and that of cancer stem cells, but co...

Recent research into cancer stem cells has refined our knowledge of the origins, maintenance, and progression cancer. The characteristics tumor initiating stem-like properties side populations that appear to be responsible for maintenance metastasis have given insights potential targets elimination treatment-resistant residual cells. These also provided inroads understanding preventing invasive...

Emerging evidence suggests that the capacity of a tumor to grow and propagate is dependent on a small subset of cells within a tumor, termed cancer stem cells. In fact, cancer cells, like stem cells, can proliferate indefinitely through a dysregulated cellular self-renewal capacity. Cancer stem cells may originate due to the distribution into self-renewal and differentiation pathways occurring ...

Lung cancer stem cells are a subpopulation of cells critical for lung cancer progression, metastasis, and drug resistance. Thioridazine, a classical neurological drug, has been reported with anticancer ability. However, whether thioridazine could inhibit lung cancer stem cells has never been studied. In our current work, we used different dosage of thioridazine to test its effect on lung cancer...
