Objective:
The objective of this study was to find keratinocyte growth factor (KGF) mimic peptides by a phage display library screening and to analyze their effects on proliferation of human oral mucosal epithelial cells (HOMECs).
Study Design:
A phage display library was screened by anti-KGF antibody. ELISA was performed to select monoclonal phages with higher binding activity. The promotion of the phage model peptides on HOMEC proliferation were analyzed by MTT and their cell affinities were confirmed by immunofluorescence assay. Their effect on KGFR, human beta-defensin 3, c-Fos, and c-Jun in HOMEC were analyzed by quantitative real-time PCR.
Results:
Two model peptides with higher affinity with HOMEC were found to have promotive activity on cell proliferation, similar to that of KGF. These 2 model peptides have no KGF-like promotion effect on the expression of c-Fos and c-Jun.
Conclusions:
The 2 phage model peptides can promote the proliferation of HOMEC in vitro without tumorigenic effects, which suggests their possible usages in oral mucosal wound healing.
