Cancer Stem Cells
Cancer stem cells (CSCs) are the certain immortal cells within the tumor or hematological regions that possess characteristics related to the normal stem cell and they are capable of proliferating into all other types of cancer cells Cancer stem cells specifically have an ability to give rise to all cell types found in a particular cancer sample. Cancer stem cells are the primary targets of cancer biologist and oncologist for treatment of various tumors, even though they are fairly resistant to chemotherapy and radiotherapy. These cells give rise to new tumors by metastasis and relapse caused by hypothesizing the stem cells to persist in tumors as a distinct population. Approaches have been made to exploit the property of these cells to develop immortal cell lines for the production of drugs and cytokines relevant to medical use, but, a lot more understanding is required before bringing the results in practice.
