Figure 2. Fibroblast induction of fibronectin by BALF is greater from recipients who develop OB.

Fibroblasts transfected with a fibronectin promoter-luciferase reporter construct were cultured with BALF for 72 hours. Fibronectin gene transcription was higher in fibroblasts exposed to BALF from the OB groups when compared to that from the non-OB group.
