[The expression of Cyclin A and p21cip1 in fibroblast of hypertrophic scar].

Objective: To study the relation of the mRNA and protein expression of Cyclin A and p21cip1 in different stages hypertrophic scar fibroblast (FB) with its cell cycle, so as to provide theoretical evidence for intervention therapy of cell cycle gene being used in hypertrophic scar.

Methods: The hypertrophic scar samples at different stages (the third month, the sixth month, the twelfth month, the twenty-fourth month) in 32 cases and the normal skin samples in 8 cases were used in this study. The expression of Cyclin A, p21cip1 mRNA and protein was detected by quantitative real-time PCR and Western Blot.
