Figure 4. Analysis of the spatial expression patterns of the fgf7 and fgf9 subfamilies. A: Whole mount in situ hybridisations of fgf3, fgf7, fgf10, and fgf22 at the indicated stages. B: Whole mount in situ hybridisations of fgf9 and fgf20 at the indicated stages. For stage 10.5, the images are vegetal views; for stage 15, the images are dorsal views; and for stage 23, 28, 35, and 40, the images are lateral views (anterior is left, posterior is right, dorsal is up, and ventral is down). A schematic representation of a Xenopus embryo at stage 28 with the different embryonic tissues labelled is presented in Supp. Figure S3.
