[Discoidin domain receptors (DDRs) expression in pathological scar fibroblast formation].

Objective: To explore the role of discoidin domain receptors (DDRs) in the formation of the keloid.

Methods: The real-time quantitative PCR was used to compare the DDRs expression in the keloids and normal fibroblasts.

Results: The level of DDR1 expression was significantly higher in keloid than in normal fibroblast (20.
