Fig. 2

The attachment of the 1^st tooth occurs on time in ext2^-/- mutant.

The expression of the osterix gene at 96 hpf underlines the pharyngeal arches in sibling (A, A2) and ext2^-/- mutant (B, B2). At this stage, osterix is also expressed in the sibling in the tooth germs of 3V¹ and 5V¹, but lost in the 4V¹. Mineralised dentine outlines the first to develop and attach – the 4V¹ tooth. Note that single tooth that does not express osterix is also attached into osterix-positive pharyngeal arch in the ext2^-/- mutant. A2 and B2 are higher magnification images of A and B. Scale bar = 0.1 mm.
