Research Abstract

The purpose of our study is to clarify the mechanism of cleft palate development from the interaction of the signal transduction in cells and molecules from the phenomenon of cleft palate after palatal fusion. We observed disappearance of Perlecan and IVcollagen in the basement membrane of the epithelial funiculus when both palatine processes were fusing. We observed Laminin positive cells in the basement membrane of the nasal side. And the localization of PCNA positive cells was observed in the entire of palatine processes previous palatal fusion, suggesting that cell proliferation have been active.
