Figure 4. Expression patterns of selected retinoic acid receptor (RAR) target genes. Expression pattern of selected upregulated genes at stage 18 and stage 22 were determined by whole-mount in situ hybridization. Embryos were hybridized with probes made from indicated expressed sequence tag (EST) clones. The staining patterns in whole and sectioned embryos were summarized and used to categorize the genes broadly into four groups (group 1, 2, 3, and 4) by expression patterns. The signature staining of group 1 is present in the neural tube, neural crest, and optic anlagen; the staining patterns of group 2 are similar to those of group 1 but absent from the neural crest. Group 3 genes show staining in the neural tube but not in the optic anlagen. Group 4 genes have staining in the lateral plate mesoderm where RALDH2 is predominantly expressed. A, B, and C are in group 1; D, E, and F are in group 2; G, H, and I are in group 3; and J, K, and L are in group 4. A1-L1, A3-L3, M1-R1, and M2-R2: dorsal view; A2-I2 and A4-I4: anterior view; C6 and J2-L2: lateral view; C7: ventral view; C5: J4-L4 and M3-R3: sagittal section of stage 22 embryos. VLCS, very-long-chain acyl-CoA synthetase; Hypothetical, similar to ESTs from other organisms; Unidentified, no significant similarity to database sequences from any organism; Sm, somites; rp, roof plate of the neural tube; no, notochord; nt, the neural tube.
