Characterization of the norepinephrine uptake system and the role of norepinephrine in the expression of the adrenergic phenotype by quail neural crest cells in clonal culture.

Abstract excerpt

This study investigates the role norepinephrine (NE) may play in regulating the differentiation of quail neural crest cells into sympatho-adrenal cells. Cues originating from the embryonic microenvironment are thought to play an important role during development. It is conceivable that NE has a positive regulatory function because adrenergic expression by quail neural crest cells in clonal culture can be...
