Fig. 4

Comparative distribution of some key genes for the activation of the Dpp pathway. Images show the mRNA distribution, observed by in situ hybridization, during cellularization of M. domestica (a, c, e, g) and D. melanogaster embryos (b, d, f, h), revealed by in situ hybridization. In panels ad, g and h, lateral views of the expression of short gastrulation (sog), tolloid and brinker are shown. Panels e, f show a dorsal view of the expression of tolloid where differences in the amplitude of the pattern can be observed. In all the images, embryos are oriented with the anterior region to the left
