We have previously investigated PG synthesis in cultured oral epithelial cells, 6 human gingival fibroblasts, 7 and human periodontal ligament cells 8 and reported syndecan-3 mRNA expression in human periodontal tissue cells. 8 In the present study, we investigated the expression of syndecan-1 in mice oral epithelial tissue undergoing eruption and that in differentiation stages.…”
