The aim of this study was to evaluate the role of epithelial Signal transducer and activator of transcription 3 (STAT3) in mouse incisor amelogenesis. Since Stat3 is expressed in the epithelial component of developing and adult mouse teeth, we generated and analyzed Krt14Cre/+;Stat3fl/fl mutant mice in which Stat3 was inactivated in epithelia including ameloblast progenitors and ameloblasts – the cells responsible for enamel formation. Histological analysis showed little enamel matrix in mutant incisors compared to controls. Delayed incisor enamel mineralization was demonstrated using micro-computed X-ray tomography (microCT) analysis and was supported by an increase in the pre-expression distance of enamel-enriched proteins such as amelogenin (AMEL), ameloblastin (AMBN), and Kallikrein4 (KLK4). Lastly, scanning electron microscopy (SEM) analysis showed little enamel mineralization in mutant incisors underneath the mesial root of the 1st molar, however, the micro-architecture of enamel mineralization was similar in the erupted portion of control and mutant incisors. Taken together, our findings demonstrate for the first time that the absence of epithelial Stat3 in mice leads to delayed incisor amelogenesis.
