Much remains to be elucidated regarding the topographic development of the elastic fiber system that constitutes the walls of the digestive organs. This study aimed to examine the topographic development of the elastic fiber system in the periodontal tissue, oral cavity and digestive tract of rats at light- and electron microscopic levels. At embryonic day 20, in situ hybridization revealed the mRNA expression of tropoelastin in the putative gingival lamina propria but not in the dental follicle. At the postnatal stage, the masticatory mucous membrane of the gingiva and hard palate comprised three different types of elastic system fibers (oxytalan, elaunin and elastic fibers). Conversely, the elastic fiber system comprised elaunin and elastic fibers in other oral mucosae and the lining mucosae of digestive tract organs (the esophagus, stomach and small intestine). The findings of our study suggest that the elastic fiber system is mainly related to tissue resistance in the periodontal ligament and tissue elasticity in the oral mucosae without masticatory mucosae and the overlying mucosa of digestive tracts and both functions in the gingiva and hard palate, respectively. The appearance of elaunin fibers in the periodontium of rats aged 14 weeks suggests the expression of tropoelastin induced by mechanical stressors such as mastication. The intraperiodontal difference in the distribution of elaunin fibers suggests heterogeneity among fibroblasts constituting the periodontium.","PeriodicalId":48655,"journal":{"name":"Microscopy","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2019-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1093/jmicro/dfz030","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49533922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
