Luteolin inhibits the lung metastasis in B16F10 melanoma tumor. In the experimental metastasis model, all the mice were sacrificed on the 23rd day after tumor injection (A). Their lungs were then removed and fixed, metastatic foci at lung surfaces were photographed (B) and the number of lung metastases foci in each group were detected (C). Mean±SEM. n=5. ^cP<0.01 vs control.
