Abstract
PURPOSE
To investigate the expression of Krüpple-like factor 5 (KLF5) in human pulp-dentin complex and the function of KLF5 in differentiation and dentinogenesis of odontoblasts.
METHODS
Immunohistochemistry staining was used to investigate the expression of KLF5 in human pulp-dentin complex and dental pulp cells. Western blot was used to analyze the expression patterns of KLF5 during dental pulp cell differentiation. Significant differences between groups were evaluated using one-way ANOVA and Tukey's test with SPSS17.0 software package.
RESULTS
Immunohistochemical staining showed KLF5 was positively expressed in the odontoblasts and odontoblast-like cells, but not in dentin and predentin in both normal and carious teeth. Moreover, during mineralization of human dental pulp cells, KLF5 was primarily localized in the nuclei of dental pulp cells. Western blot showed KLF5 was significantly up-regulated during odontoblast differentiation.
CONCLUSIONS
KLF5 may play an important role in odontoblast differentiation and dentin formation.
