Histology and expression of protein markers in BIN-67 tumours. A) BIN-67 cells form large tumours in SCID mice. B-D) H&E staining of the tumours indicates that the histology resembles human small cell ovarian cancers, with homogeneous sheets of small cells and follicle-like structures (B). E-L) Immunohistochemical staining for cytokeratin, α-synaptophysin, KIT, Pgp9.5, vimentin, inhibin, p53 and WT-1. B: 10X; C, I-L: 20X; D-H: 40X.
