Fig. 7.

Arterial assembly in a chick mesonephros (MES) grafted onto quail CAM. (A,B) General view of QCPN and HHF35 stained serial sections showing the positive binding of the HHF35 to the arteries (arrows) which penetrate to supply the graft. Peripheral regions presented a great invasion of QCPN quail-positive cells (arrowheads). Scale bar = 100 µm. (C) Detail of a consecutive section stained with QCPN showing the connection between quail and chick arteries. The arterial assembly shows as the endothelial cells of the graft are surrounded by host smooth muscle cells. (D) View of a serial section stained with HHF35 demonstrating the nature of the smooth muscle cells around the artery. A, artery. Scale bar = 48 µm.
