Specifically, in FOXL2+COL1A1− cells, we examined expression of other AGCT tumor markers such as SF1, calretinin, and inhibinα, whereas in FOXL2+COL1A1+ cells, we also examined expression of stromal markers, including αSMA, vimentin, S100A4, PDGFRa, PDGFRb, and FAP. Here, S100A4 is linked to neoplasm.
