AIM : To explore the inhibiting effect of FTY720 on corneal neovascularization( CNV) of rat.METHODS: MTT assay and cells scratch were adopted to observe hyperplasia of human umbilical vein endothelial cells( HUVECs) and cell migration induced by sphingosine-1-phosphate( S1P) after using FTY720 of different concentration. The effect of FTY720 on CNV induced by S1 P in a rat corneal micropocket model was detected. 30 SD rats were randomly divided into group A,group B and group C with 10 rats per group. S1 P a...
