Pattern of grm8a and grm8b expression in the developing zebrafish revealed by whole-mount RNA in situ hybridization. (A) Grm8a expression at 24, 36, and 48 hpf in the developing zebrafish. Lateral (top) and dorsal (bottom) overviews indicate expression as early as 24 hpf in the central nervous system. (B) Grm8b expression at 24, 36, and 48 hpf in the developing zebrafish. Lateral (top) and dorsal (bottom) overviews indicate prominent expression as early as 24 hpf in the central nervous system. Details on the individual expression patterns are described in the main text. Arrowheads indicate transcript labeling in individual cell cluster of the medulla oblongata (MO). All images are oriented with anterior to the left. Abbreviations are listed in Table 1. Scale bar is 100 μm.
