Gene expression of markers involved in lung injury and wound healing. Gene expression of (A) gremlin1, (B) CCL12 (MCP-5), (C) TIMP1, (D) CCL3 (MIP-1α), (E) IL-4, (F) IL-5, (G) TNF-α, and (H) integrin-β8, are all presented as mean ± standard error of the mean (SEM). All samples from the bleomycin group are related to the mean of control and normalized to the geometric mean of five different reference genes. Each presented group/time point contains n = 48. Significance is indicated by * when p < 0.05; p < 0.01 by **; p < 0.001 by *** and p < 0.0001 by ****, when comparing bleomycin towards the saline control. The comparison of various time points between bleomycin-challenged groups is expressed as # when p < 0.05; ## when p < 0.01; ### when p < 0.001 and #### when p < 0.0001.
