(A) Transverse section of a human tooth germ stained with hematoxylin and eosin (H&E). Higher magnification views of several portions of the tooth germ indicated by alphabetized squares were shown in panel B; and (B) Higher magnification views of characteristic areas of the tooth germ. Mel1aR was noted to be expressed in ameloblasts (am), stratum intermedium cells (si), stellate reticulum cells (sr), odontoblasts (od) and dental papilla cells (dp). H&E: hematoxylin and eosin staining. Mel1aR: 3,3'-diaminobenzidine (DAB) and hematoxylin staining. Negative control: normal mouse IgG. Scale bars = 25 µm.
