Cross section images showing the distribution of EphA4 and EphB1 mRNA and HNK-1 protein in the hindbrain region of the stage 14 chicken embryo. EphA4 probe binding cells overlap with cells stained by HNK-1 (arrowheads) (a, b). This is also the case with EphB1 (c, d). Insets show the same sections at lower magnification. Ec, ectoderm; My, mesenchyme; s, somite; BA, branchial arch; OV, otic vesicle.
