Technological innovations promote cancer stem cell-based translational research

Cancer remains one of the leading causes of death worldwide, with therapy resistance and tumor recurrence driven by a subpopulation of cells known as cancer stem cells (CSCs). CSCs possess a remarkable ability to evade apoptosis, adapt to harsh microenvironments, regenerate tumors, and exhibit metabolic flexibility along with enhanced DNA repair mechanisms. The tumor microenvironment (TME) plays a critical role in supporting CSCs. Stromal cells, extracellular matrix components, and hypoxic niches provide both physical and biochemical support, promoting CSC survival and resistance to therapy. Recent advancements in techniques, such as single-cell sequencing, functional genomics, organ chip platforms, and artificial intelligence (AI), have enabled a deeper understanding of the molecular regulatory mechanisms governing CSCs, and facilitated the development of targeted interventions. This article provides a comprehensive overview and prospectives of CSC-based therapeutic strategies benefiting from technological developments.
