Interestingly, these authors showed that the intraperitoneal injection of CD44+MyD88+ epithelial ovarian cancer cells generated ovarian tumors, followed by carcinomatosis; mesenchymal spheroids were equally able to generate these tumors when inoculated into the peritoneal cavity; the tumors generated by both types of ovarian cancer cells have the same histological features [231]. This evidence concerns the gene MYD88 and ovarian carcinoma.
