 Treatment of Ovarian Cancer by Targeting the Tumor Stem Cell Associated Carbohydrate Antigen, C.L.L. Thompson Nuvo. Researchers believe recurrent ovarian cancer may result from rare, quiescent cancer stem cells that survive chemotherapy and drive tumor resurgence. In a trending paper published by Oncotarget in 2018, researchers aimed to eliminate cancer stem cells by targeting STN and CD-133 markers in a subset of human ovarian cancer cell lines.
