Autocrine expression of osteopontin contributes to PDGF-mediated arterial smooth muscle cell migration

Abstract

The present study demonstrates that the autocrine expression of OPN plays a major role in PDGF-induced SMC migration. It further shows that the transcription factor CREB, activated in PDGF-stimulated SMCs, plays a key role in PDGF-induced SMC migration, probably by regulating OPN expression.
