Purpose: Vascular endothelial growth factor (VEGF) is known as a growth factor of endothelium and fibroblast. The purpose is to know the VEGF effects on fibroblast proliferation and fibroblast’s notch receptor expression.
Methods: CCD-986sk fibroblast was purchased from the Korean Cell Bank and was used in XTT assay for proliferation and wound healing assay for migration. Immunofluorescent (IF) staining and western blotting were used in testing notch expression of fibroblast. Semiquantitative RT-PCR was used in checking notch 1 mRNA production by fibroblast. Student-t test was used for analyzing results.
Results: Cell proliferation assay using XTT showed significant higher proliferation in VEGF treated fibroblast, 2.324 ± 0.0026 vs. 2.463 ± 0.017 (p=0.002). Wound healing assay showed longer migration in VEGF treated fibroblast (p=0.062). The fluorescence was brighter in VEGF treated cells of notch 1 IF staining. Notch 1 expressions and mRNA productions increased more in VEGF treated cells.
Conclusion: VEGF stimulates fibroblast to proliferate, migrate and to express Notch 1 simultaneously. Notch receptor could be related to VEGF mediated wound healing.
