Introduction: Sphingosine-1-phosphate (S1P) is a sphingolipid mediating proliferative signals in human ovarian follicles, acting through five receptors (S1PR1-5). We characterized the effects of S1PR1 and S1PR3 in vitro, as those mostly expressed in human primary granulosa cells (hGLC) and immortalized, tumor-like granulosa cell line (hGL5).Methods: The S1P-mediated signaling, as well as the activity of S1PR1- and S1PR3-specific agonists (SEW281...
