doi: 10.1038/s41368-019-0070-1
Figure Lengend Snippet: Immunohistochemical staining of proteins encoded by over-expressed (CK14, DSG3, PKP1) and under-expressed (POSTN, TIMP2, MMP2) genes in infraocclusion. a Hematoxylin and Eosin staining of P1 mouse molar tooth germ in the sagittal plane with various nascent structures within the dental follicle. b CK14 was strongly stained in the dental follicle. c Higher magnification of boxed area showed CK14 immunostaining in the stellate reticulum, stratum intermedium, inner enamel epithelium and ameloblast layer. d DSG3 was strongly stained in the dental follicle and to a lesser extent in the ameloblast layer. e PKP1 was strongly stained in the dental follicle, as well as the inner enamel epithelium and the apical aspect of the ameloblast layer. f POSTN was immunostained only in the dental follicle. g MMP2 was expressed only in the dental follicle and stellate reticulum. h TIMP2 was the only protein in this sample not expressed in the dental follicle, but was abundantly present in the ameloblast and odontoblast layers. Scale bars are 100 μm
