Expression patterns of PTC1 in the developing human and mouse tooth germs at the cap and bell stages. (A) Ptc1 expression in E14.5 mouse molar. (B) PTC1 expression in 12-week human primary incisor. (C) PTC1 expression in 12-week human primary canine. (D) PTC1 expression in 12-week human first premolar molar. (E) Ptc1 expression in E16.5 mouse molar. (F) PTC1 expression in 14-week human primary incisor. (G) PTC1 expression in 14-week human primary canine. (H) PTC1 expression in human primary first premolar molar. DE, dental epithelium; DP, dental papilla; IEE, inner enamel epithelium. Scale bar = 100 μm.
