| Outline of Final Research Achievements |
Gingival recession is a frequent symptom and disturbs the patients' satisfaction, a cause of which is believed quality of gingiva. As thick and highly keratinized gingiva withstands recessing, 3D culture system of keratinocyte could be useful to detect the factors determining thickness and keratinization of gingival epithelium and to develop the future diagnostic method of gingival quality. We have established a 3D culture model using keratinocytes alone creating a proper keratinized epithelial equivalent, and furthere have identified some essential factors to produce the equivalent. Calcium is the essential for stratification and differential of keratinocytes. Addition of keratinocyte growth factor (KGF), but not ascorbic acid, prolongs a life span. Further addition of ascorbic acid improves the tissue architecture in cooperation with KGF.
