Extended Data Figure 7 : In vivo inhibition of SHH in Eda null embryos causes the formation of separate cusps without crests.

Extended Data Figure 7

Obliquely anterior views and tomography sections (along the plane of the dotted line) of second molars show the lack of a crest (metalophid, arrowheads) in treated Eda null and Tribosphenomys minutus (V10775). Enamel in sections shown in blue colour except in Tribosphenomys fossil which did not allow segmentation of enamel due to high degree of mineralization. Scale bar, 500 µm.
