| Outline of Final Research Achievements |
The purpose of this study is to develop a new cultured cell sheet effective for periodontal tissue regeneration. Amniotic membrane is a biomaterial that has anti-inflammatory and anti-infective properties and its attention as a useful and effective substrate for various cells. We have previously prepared cultured human periodontal ligament fibroblast (hPdLF) sheets using amniotic membrane as a substrate and reported that they have the ability to regenerate new bone (periodontal tissue) when transplanted into experimental animals. We also found that the use of amniotic membrane as the culture substrate for hPdLF promoted the production of chemokines SDF-1 / CXCL12 and CXCL14, and found the usefulness of amniotic membrane.
