From: Divergent roles for Eph and Ephrin in Avian Cranial Neural Crest
Images of cross-sections showing the distribution of EphA3, EphA7, and EphB3 mRNA and HNK-1 protein in the hindbrain region of the stage 14 chicken embryo. 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.
