Cells labeled by EphA3 probe and HNK-1 antibody (arrowheads) form a narrow, sub-ectodermal band that reaches from the neural tube to the branchial arches (a, b)

This is also the case with EphA7 (c, d) and EphB3 (e, f). Insets show the same sections at lower magnification. BA, branchial arch; 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>
