Expression of SHH in human and mouse tooth germ at the cap and bell stages. (A-D) SHH expression at the cap stage. (A) E14.5 mouse molar; (B) 12-week human primary incisor; (C) 12-week human primary canine; (D) 12-week human first premolar molar. (E-H) SHH expression at the bell stage. (E) E16.5 mouse molar; (F) 14-week human primary incisor; (G) 14-week human primary canine; (H) 14-week human primary first premolar molar. (I-L) Histology of mouse and human tooth germs at the cap stage. (I) E14.5 mouse molar; (J) 12-week human primary incisor; (K) 12-week human primary canine; (K) 12-week human primary first premolar. DE, dental epithelium; EK, enamel knot; IEE, inner enamel epithelium. Scale bar = 100 μm.
