Regulation of PDGF-BB Signaling in Placental Pericytes by Soluble PDGFRβ Isoforms: Implications for Fetoplacental Vascular Development

Audra Barnes, Emily C. Duggan, Reese Dunkenberger…·John C. Chappell

This study identifies progressive pericyte recruitment to placental capillaries and shows that soluble PDGFRβ isoforms modulate PDGF-BB signaling in response to hypoxia.
