英文摘要
Objective In order to determine the influence of bFGF on the biological characteristics of osteoblasts and periodon- tal ligament cells, the author investigate the influence of bFGF on the migration, proliferation of osteoblasts and periodontal liga- ment fibroblasts between osteoblasts and fibroblasts.Methods The forth generation of osteoblasts and periodontal ligament fibro- blast were obtained and the woundingmodelin vitroof themwas founded. The cellswere cultured in mediumswith orwithout bF- GF. Their migration and proliferation were observed and measured.Results Osteoblasts migrated faster than fibroblasts in com- mon culture mediumwithout bFGF and the periodontal ligament fibroblasts in culture mediumwith bFGF had higher migration rate than other groups. bFGF promoted the proliferation of both two kinds of cells.Conclusion bFGF could accelerate periodontal fi- broblasts′proliferation and migration.
