Immunohistochemical staining shows that SATB1 is present in mouse incisors in a cell- and stage-specific manner. In a representative sagittal section of the incisor from 20-week-old wt C57BL/6J female mouse, SATB1 immunostaining signal (in red) was intense in PAB (a2), reduced in SAB (a3), then moderately increased in transition stage ameloblasts (TAB) (a4), and significantly reduced last in maturation ameloblasts (MAB) (a5). SATB1 could not be detected in cells of the cervical loop (CL; a1), stratum intermedium (SI; a3), and papillary layer (PL; a4 and a5). Scale bars in a1a5, 50 μM
