Published: January 2006

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.
