Fig. 5. Comparison of expression domains of DV patterning genes in the embryonic Drosophila and mouse CNS. (A,B) DV gene expression (as indicated by colour code) in the embryonic CNS of Drosophila at developmental stage 11 (A; compare Fig. 3) and mouse at 10 days after gestation (B). Note, that anteriorly, the extent of expression is specific for each gene. Regional variabilities in the DV expansion of the respective expression domains is neglected. Mouse expression data are from Shimamura et al. (Shimamura et al., 1995) (Nkx-2.2), Valerius et al. (Valerius et al., 1995) (Gsh-1) and Shimeld et al. (Shimeld et al., 1996) (Msx-3). MD, MX, LA indicate mandibular, maxillary and labial neuromer; rh1-8, rhombomeres 1-8, respectively.
