Abstract

Objective Study the expression of PCNA under different mechanical tension on the transformation of normal skin fibroblasts (NSFB) to hypertrophic scar fibroblasts(HSFB). Methods NSFB and HSFB were divided into the stretch group and the control group. Stretch groups were loaded with 0.1Hz, 10% amplitude cyclic stretch for 3, 5 and 7 days respectively. Control group were cultured without cyclic stretch. At the end of experiments, cell proliferation was determined by CCK8, immunocytochemistry(ICC)of proliferating cell nuclear antigen (PCNA). Results When loaded for 5 days with amplitude cyclic stretch, compared with HSFB control group, expression levels of PCNA of the NSFB stretch group were no significant differences (P>0.05); while loaded for 3 days or 7 days, the above indexes showed significant differences (P<0.05). Conclusion The effect of mechanical tension for 5 days is the best time, which can induce normal skin fibroblasts to show some biochemical characteristics of hypertrophic scar fibroblasts.
