Although this small, highly heterogeneous, and restricted population of CSCs has been extensively studied, their cellular and molecular physiology remains unclear. Nonetheless, CSCs have increasingly become an attractive therapeutic target for combating advanced, treatment-resistant cancers.

Multiple studies have suggested that the fallopian tube epithelium (FTE) serves as the cell of origin of HGSOC. Phosphatase and tensin homolog (<em>PTEN</em>) is a tumor suppressor and its loss is sufficient to induce numerous tumorigenic changes in FTE, including increased migration, formation of multicellular tumor spheroids (MTSs), and ovarian colonization. In murine oviductal epithelial (MOE) cells (the equivalent of human FTE) loss of <em>PTEN</em> results in the upregulation of transcripts associated with the extracellular matrix, with a specific focus on the elevation of lysyl oxidase-like 2 (<em>LOXL2</em>). Although LOXL2 is known to drive transformation and invasion in solid tumors and is associated with a poor prognosis in ovarian cancer, its specific role in the tumorigenesis of ovarian cancer originating from FTE remains unclear.
