Cancer Stem Cells and Tumor Heterogeneity

Cancer stem cells (CSCs) are a small population of cells within tumors that possess the ability to self-renew, drive tumor growth, and are believed to be responsible for relapse and metastasis. These cells are highly resistant to conventional therapies, which often fail to target the CSCs effectively. Tumor heterogeneity, the presence of diverse cell types within a single tumor, further complicates treatment strategies. Researchers are focusing on understanding the molecular characteristics that distinguish CSCs from normal stem cells and developing therapies that specifically target these cells. Overcoming the challenges posed by CSCs and tumor heterogeneity could significantly improve cancer treatment outcomes and reduce the likelihood of relapse.
