Identification of precipitated cells from ovarian cancer ascites. a. Bloody appearance of ovarian cancer malignant ascites; b. In the group without chemotherapy, the tumor cells occupied 45.9% of the field; c. In the group with chemotherapy, the tumor cells occupied 15.3% of the field; d-1. Tumor cells predominate under light microscopy, HE× 400; d-2. The nucleus is large with increased nucleosomes under electron microscopy, EM × 6000; d-3. The expression of CA125 in the tumor cells is high, sABC× 400; d-4. The expression of HE4 is high in the tumor cells, sABC× 400; e-1. The tumor cell number was decreased under light microscopy, and some of the tumor cells appeared vacuolated, HE× 400; e-2. Most of the tumor cells were apoptotic, EM × 6000; e-3. The expression of CA125 was low in the tumor cells, sABC× 400; e-4. The expression of HE4 was weak in the tumor cells, sABC× 400
