PGE2 /EP4 antagonism enhances tumor chemosensitivity by inducing extracellular vesicle-mediated clearance of cancer stem cells

Cells expressing mesenchymal/basal phenotypes in tumors have been associated with stem cell properties, while cancer stem cells (CSCs) are often resistant to conventional chemotherapy. A team led by Dr. Hua-Jung Li from the Institute of Cellular and System Medicine, explored overcoming mesenchymal CSC resistance to chemotherapeutic agents with the goal…
