Figure 4From: Lung fibroblasts from patients with emphysema show markers of senescence in vitro Relative expression of target genes obtained by qPCR in control patients and patients with emphysema. Data points represent normalized ratios of gene expression relative to PBGD and corrected for qPCR calibrators (dotted line: median value). Values are expressed on a log-scale. Panel A: IGFBP-3 expression, Panel B: IGFBP-rP1 expressionBack to article page
