Pdgfb	Ad-Cre 5 MOI	0.678	0.484–0.884
	10 MOI	0.645	0.586–0.703
	20 MOI	0.617	0.261–0.981
Pdgfc	Ad-Cre 5 MOI	0.586	0.533–0.666

	20 MOI	0.291	0.147–0.445

Data are normalized by the reference gene β2-microglobulin. The TGFβ1 treated groups are compared with the un-treated group for each gene, and the Ad-Cre treated groups are compared with the Ad-GFP (10 MOI) treated group for each gene.
