Axial bending in the early chick embryo by a cyclic adenosine monophosphate source.
A microelectrode continuously releasing cyclic adenosine monophosphate can divert the axis of the early chick embryo and attract cells on its ventral surface. Cell movement in the intact embryo may be controlled by a cyclic adenosine monophosphate signal.
