Fig. 3From: Mangiferin suppresses human metastatic osteosarcoma cell growth by down-regulating the expression of metalloproteinases-1/2 and parathyroid hormone receptor 1Mangiferin effect on the osteosarcoma cell apoptosis. Cells were incubated with mangiferin (50–100 µM) for 72 h. a: represents the Annexin-VFITC of Saos-2 cells, b: represents the Annexin-VFITC of U2OS cells. N = 6Back to article page
