Research Abstract

GAP junction Inhibitor related to calcium and IP3 transport inhibit the PDGF-mediated salivary glands branching. PDGF induced FGF7 and FGF10 expression in mesenchymal tissue of salivary glands. We analyzed about the MAPK pathway. PDGF induced phosphorylation of ERK1/2 in developing salivary glands. It indicates that activation of MAPK pathway on epithelial cells involves the branching of salivary glands. In Cx43 knockout mice, branching of salivary gland was inhibited compared with control mice, indicating that Cx43 may be important for salivary gland morphogenesis.
