Expression patterns of SMO in the developing human and mouse tooth germs at the cap and bell stages. (A) SMO expression in 12-week human primary incisor. (B) SMO expression in 12-week human primary canine. (C) SMO expression in 12-week human first premolar molar. (D) SMO expression in 14-week human primary incisor. (E) SMO expression in 14-week human primary canine. (F) SMO expression in human primary first premolar molar. DE, dental epithelium; DP, dental papilla; IEE, inner enamel epithelium. Scale bar = 100 μm.
