Abstract
The interaction between circulating tumor cells and blood components, mainly platelets, plays an important role during metastasis. In this study, we prepared liposomes containing the platelet aggregation inhibitor Cilostazol (Cil-L). The objective of this study was to investigate the effect of this Cil-L on platelet aggregation and complex formation with murine 4T1 breast cancer cells in vitro and to determine their anti-metastatic potency in a spontaneous metastasis model of 4T1 breast cancer. Cil-L significantly inhibited the aggregation of platelets by up to 78% and completely abolished the complex formation of 4T1 tumor cells in the presence of activated platelets in vitro. Intravenous (i.v.) injection of Cil-L into mice significantly reduced the aggregability of mouse platelets by 60% measured ex vivo. To gain deeper insight into the mode of metastasis formation in a spontaneous metastasis model, 4T1 breast cancer cells were transplanted into the mammary fad pad of mice and metastasis to the mouse lungs was investigated with regard to tumor cell settlement and metastatic growth. We could demonstrate that the formation of pulmonary metastases was significantly reduced by 55% when mice were treated intravenously with 100 nmol Cil-L 6 h before tumor cell inoculation and then daily for 2 weeks. We conclude that Cil-L reduced metastasis by restricting the aggregability of mouse platelets, which probably prevents the interaction between circulating 4T1 tumor cells and platelets, making the Cil-L a useful tool for the inhibition of breast cancer metastasis in mice.
