Wholemount (a-c) and cross-section (d-f) images of a stage 14 chicken embryo double labeled for EphB2 and HNK-1

(a-c) EphB2 probe staining is in patches (arrows) bordering cells labeled by HNK-1. Inset shows embryo at lower magnification. The margins of the regions expressing EphB2 have been traced with a thin white line in panel a. The tracing from panel a has been superimposed on the image in panel b to show the margins relative to the HNK-1 expressing cells. (d-fi) In cross-section (taken at black line in c), probe (arrow) and HNK-1 stained cells have a non-overlapping distribution. Inset shows section at lower magnification. Ec, ectoderm; My, mesenchyme; s, somite.<p><b>Copyright information:</b></p><p>Taken from "Divergent roles for Eph and Ephrin in Avian Cranial Neural Crest"</p><p>http://www.biomedcentral.com/1471-213X/8/56</p><p>BMC Developmental Biology 2008;8():56-56.</p><p>Published online 21 May 2008</p><p>PMCID:PMC2405773.</p><p>
