Objective: To study the mechanism of integrin in hypertrophic scar.
Methods: Fibroblasts from 10 samples of human hypertrophic scars was cultured, FQ-PCR assay was applied to detect mRNA expression of alpha-SMA in hypertrophic scar fibroblasts after integrin and FAK antibody blocking.
Results: mRNA of alpha-SMA in fibroblasts expressed obviously lower after integrin and FAK antibody blocking than that of control groups ( P < 0.05).
Conclusion: Through accelerating the synthesis of alpha-SMA, integrin and FAK play an important role in contracture of hypertrophic scar.
