Inhibitory Effect of Astragalus Polysaccharide on Premetastatic Niche of Lung Cancer through the S1PR1-STAT3 Signaling Pathway

Figure 1

APS inhibited the formation of the lung premetastatic niche and thus prevented metastasis. (a) Changes in body weight in the blank group, model group, APS-L group, APS-M group, APS-H group, and FTY720 group over 28 days. (b) The small animal live fluorescence imaging in the blank group, model group, APS-L group, APS-M group, APS-H group, and FTY720 group on days 7, 14, and 21 after tumor inoculation.
