Figure 5

Cephalic NCC contribution to the cardio-vascular system. A) Refined colourcoded cephalic neural fold of a 5 somite-stage chick embryo and NCC contribution to the musculo-connective wall of artery tree in the head. B) Prosencephalic meninges (in pink) derive from the diencephalic and mesencephalic NCCs; from mesencephalon down to more caudal cephalic structures, meninges (in grey) are of mesoderm origin. C) Contribution of the posteriormost rhombencephalic NCCs to the conotruncal structures of the heart. D) NCCs form the musculo-connective wall of chimeric cephalic artery (QCPN immunoreactivity of quail rhombencephalic NCCs grafted into chick host embryo). A: aorta; AV: atrioventricular valve; IVS: intraventricular septum; PA: pulmonary artery; SA: sinoatrial valve; SL: semilunar valve.
