As there were published data showing that TGFBI can be produced by fibroblasts and peritoneal cells, and may aid the spread of ovarian cancer cells throughout the peritoneal cavity by increasing their adhesive, mobile, and invasive potential (28, 29), we focused on TGFBI, conducting RNA scope ISH on healthy and diseased FT, FB, and OV. The gene discussed is TGFBI; the disease is ovarian cancer.
