Cancer stem cells (CSCs) are implicated in tumor relapse due to chemoresistance. We have optimized a protocol for selection and expansion of CSCs from ovarian cancer cell lines. By treating cells with the chemotherapeutic cisplatin and culturing in a stem cell promoting media we enrich for non-adherent CSC cultures.
