Figure 3From: Dose-response relationship in cisplatin-treated breast cancer xenografts monitored with dynamic contrast-enhanced ultrasoundHistopathologic analysis of tumor cell density changes after treatment with different dose cisplatin. (A) Tumor cell density significantly decreased in groups B and C when compared with group A (* = P < 0.05), and further decreased in group C when compared with group B (* = P < 0.05). (B) Photomicrographs of HE stained sections of the three groups on days 0, 3, and 7. Scale bars: 50 μm.Back to article page
