Research Abstract

In this study, we have developed a serum-free culture system of human periodontal ligament-derived epithelial cells (Epithelial rests of Malassez : ME) derived from Hertwig's epithelial root sheath.
The mitogenic effect of fibroblast growth factor (FGF) in the ME and human periodontal ligament-derived fibroblast cells (PLF) were investigated by serum-free growth assay. In addition, we demonstrated the expression of FGF receptor (FGFR) in the ME and the expression of FGF in the PLF by reverse transcription-polymerase chain reaction (RT-PCR), PCR-Southem hybridization, ribonuclease protection assay (RPA) and immunohistochemical examinaijon.
Both FGF-1 and FGF-7/keratinocyte growth factor (KGF) stimulated cell growth of the ME.On the other hand, both FGF-1 and FGF-2 stimulated cell growth of the PLF.RT-PCR and PCR-Southem analysis revealed that the ME expressed FGFR2-(IIIb) mRNA but not mRNAs for FGFR1 -(IIIc), FGFR2-(IIIc), FGFR3-(IIIb), FGFR3-(IIIc) and FGFR4. An immunohistochemical. analysis of FGF-7/KGF revealed that immunoreactive FGF-7/KGF were detected predominantly in the cytoplasm of the. PLF cells. PCR-Southem and RPA also revealed that the PLF expressed FGF-7/KGF mR.NA.
These results suggest that the FGF-FGFR2-(IIIb) system plays an important role in the growth and differentiation of ME.In addition, endogenously produced FGFs work as paracrine interactive regulators of the growth and differentiation between ME and PLF.
