Abstract:
OBJECTIVETo observe the alteration of fibroblast growth factor 10 (Fgf10) and fibroblast growth factor receptor 2 (Fgfr2b) signal in mouse embryonic palate after dexamethasone and vitamin B12 exposure.
METHODSDams were divided teratogenetic group, antagomistic group and control group and were respectively injected dexamethasone, dexamethasone and vitamin B12, and normal sodium. Dams were killed and fetus was collected at embryo 12.5 and 13.5 day. The expression of Fgf10 and Fgfr2b and mesenchymal cells proliferation of mouse embryonic by western blotting and BrdU assay were checked.
RESULTSFgf10 and Fgfr2b expression was down-regulated and mesenchymal cells proliferation was inhibited significantly after dexamethasone exposure. After vitamin B12 treatment, Fgf10 and Fgfr2b expression did not restore, but cells proliferation was recovered.
CONCLUSIONDexamethasone and vitamin B12 affected the expression of Fgf10 and Fgfr2b of mouse embryonic palate and mesenchyme cells proliferation, but the change was disaccord.
