Cancer stem cell biomarkers: critical roles, challenges, clinical applications and perspectives in cancer therapy

Progress in cancer stem cells has opened up a new window to develop better cancer treatment methods. Several pre-clinical and clinical trial studies use CSCs targeting via surface markers method and inhibition of stem cell pathway to eradicate cancer. Albite, some important question was unclear about CSCs origin and molecular mechanism of self-renewal, the structure of CSCs markers and so on, but the eradication of these cells eliminate cancer. In this review, we have argued about the CSC surface markers on different cancers, the mechanisms of action, and therapeutic procedures related to the cancer biomarkers. Then, we have discussed the challenges of these therapies.
