The expression of S1PR on the dendritic cell (DC) surface was detected by reverse transcription polymerase chain reaction. The quantity and maturation of DCs in peripheral blood and local tissues of pregnant mice, and the expression of CCL19 as well as its receptor C\u2010C chemokine receptor 7 (CCR7) were detected by flow cytometry and immunohistochemistry.

In contrast, adoptive transferring of FTY720 significantly reduced the embryo loss rate of the spontaneous abortion mouse model (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05). (2) S1PR was extensively expressed on DC surface. The S1P receptor agonist FTY720 reduced the expressions of DC surface chemokines and its receptor (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05), resulting in a significant reduction in the number of DCs that were chemoattracted to maternal\u2010fetal interface flow cytometry (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05).
