Sphingosine-1-Phosphate Induces the Migration and Angiogenesis of Epcs Through the Akt Signaling Pathway via
Abstract:
Endothelial progenitor cells (EPCs) play a fundamental role in neoangiogenesis and tumor angiogenesis. Through the sphingosine-1-phosphate receptor 3 (S1PR3), sphingosine-1-phosphate (S1P) can stimulate the functional capacity of EPCs. Platelet-derived growth factor receptor-beta (PDGFR-β) contributes to the migration and angiogenesis of EPCs. This study aimed to investigate whether S1P induces the migration and angiogenesis of EPCs through the S1PR3/PDGFR-β/Akt signaling pathway. We used the Transwell system and the Chemicon In Vitro Angiogenesis Assay Kit with CAY10444 (an S1PR3 antagonist), AG1295 (a PDGFR kinase inhibitor) and sc-221226 (an Akt inhibitor) to examine the role of the S1PR3/PDGFR-β/Akt pathway in the S1Pinduced migration and angiogenesis of EPCs.
