    Figure Lengend Snippet: A) A 9 s.s. half embryo chimera just after the operation: the dotted region corresponds to the grafted quail territory (Q) caudally to the last formed somite. The rest of the chimera is chick (C). Note that the quail and chick neural tubes are aligned (arrow). Bar: 1 mm. B) A half embryo chimera 4 days after the operation: the embryo is well developed with its wing (*) and limb (°) buds; the dotted line shows the limit between chick (C) and quail (Q) territories. The quail allantois (QAL) is present above the head. Bar: 2 mm. C) A cross section at the truncal level showing the chick intrinsic QH1 − /Sambucus + vascularization in the gut (G) and the lungs (Lu). Dorsally, the vascular tree is quail, QH1 + /Sambucus + , in particular around the neural tube (NT), the cardinal veins (*) and the umbilical vein (°). Note that the aortic endothelium (Ao) is chimeric with a part of chick EC located ventrally (arrowhead). Sambucus also labels basement membrane of epithelia in gut, lung and liver (L).

    Article Snippet: Biotinylated Sambucus nigra lectin (1/400 in PBLEC buffer-PBS pH6.8, 1 mM CaCl2, 1 mM MgCl2, 0.1 mM MnCl2, 1% triton) recognizes chick and quail EC (Clinisciences, ) but also avian macrophages.
