Research Abstract |
Normal palate develops through the vertical growth, the bilateral elevation and fusion. We investigated expression of TGT beta and PTHrP in this fine process of the palate development using immunohistochemistry and in situ hybridization. Expression of both factors were recognized in the epithelium of palatal shelves and the mesenchymal condensation for bone. Concerning administration of Vitamine A induce cleft palate in pregnant rodents, reduction of PTHrP expression in embryonic facial tissue and decrease of DNA synthesis were also recognized from Vitamine A administration. However we could not show a good result of intra-amniotic administration of anti-sense S-oligo DNA for PTHrP.Although FITC-oligo was confirmed to be taken to the embryo, no remarkable change was observed. From now on, we would use organ culture, and attempt to elucidate the cleft-palate etiology.
