Establishment of immortalized ovarian stromal cell lines using Sendai virus vectors: a platform for studying tumor-stroma interactions and carcinogenesis.

ABSTRACT: We aimed to generate immortalized stromal cell lines from the ovarian and fallopian tube tissues of a single patient using Sendai virus (SeV) vectors and identify candidate stromal genes involved in ovarian carcinogenesis. Tissues were collected from a 48-year-old woman with endometrioid borderline tumors and endometriomas. Primary cultures were established from the right ovarian endometrioma, left ovarian surface, bilateral fallopian tube, and endometrial surface. Immortalization was achieved using SeV vectors encoding human telomerase reverse transcriptase (TERT), B lymphoma Mo-MLV insertion region 1 homolog (Bmi-1), and Simian virus 40 large T antigen (SV40T). Morphologically, the established cells exhibited spindle-shaped fibroblast-like features and expressed stromal markers (Vimentin
