Overexpression of SPNS2 or of MFSD2B, both known S1P efflux transporters, in TKO cells increased the direct uptake of S1P, whereas knockout of MFSD2B in TKO cells reduced this uptake. These results suggest that these are channel-type transporters and are capable of not only exporting, but also importing S1P. Furthermore, we observed that MEDEP-E14 cells, erythroid cells expressing MFSD2B, exhibited high S1P uptake activity. Our findings describing direct S1P uptake may contribute to the elucidation of the mo
