Figure 5From: The buccohypophyseal canal is an ancestral vertebrate trait maintained by modulation in sonic hedgehog signalingExpression pattern of Shh pathway-related genes in Gas1-/-mutants. At E10.5, the expression patterns of Shh, Bmp4, Bmp2, Fgf8 and Fgf10 are similar in wild-type and Gas1-/- mutant mice. The expression territory of Ptch1 and Gli1 are nevertheless reduced posteriorly and apically within Rathke’s pouch. H&E, hematoxylin and eosin.Back to article page
