The arrows in A-D point to expression in the neuroectoderm of the respective body segment. The arrows in F, J, N, R denote the expression surrounding the maxillary sensory organs. The squares and asterisks in G, K, O, S denote expression of Gm-wg in the internal and external lobe, respectively. Stages are as indicated in the top right corner of the panels.
