Role of neuregulin-1β in dexamethasone-enhanced surfactant synthesis in fetal type II cells

•Dexamethasone elevates neuregulin-1β concentration in fibroblast-conditioned media.•This effect is not the result of increased neuregulin-1β gene expression.•Surfactant phospholipid synthesis in type II cells is stimulated by neuregulin-1β.•It is concluded that neuregulin-1β is a likely component o...
