Identification of CD109 in the extracellular vesicles derived from ovarian cancer stem-like cells.

ABSTRACT: Ovarian cancer is the deadliest gynecological cancer because it has few early symptoms and metastasizes to the surrounding organs at advanced stages. Cancer stem cells (CSCs), a subpopulation of cells with acquired drug resistance, contribute to the recurrence and poor prognosis of ovarian cancer. CD109, a cell surface glycoprotein, has been reported to be a marker of CSCs; however, it remains unclear whether CD109 is secreted by CSCs. In this study, we investigated the amount of CD109 in conditioned media (CM) of CSC populations from ovarian cancer cell lines and patients with ovarian cancer. The CM of sphere-forming CSCs isolated from ovarian cancer cell lines (A2780 and SKOV3) had higher levels of CD109 than those isolated from their adherent cultured parental cells. Furthermore, higher
