An important pathological feature of senescent fibroblasts is the SASP and while the SASP of IPF‐LFs has previously been described, its characterization was limited to the gene expression of a few inflammatory genes.24 In this study, the levels of IL‐6, CCL2, CCL5 and IGFBP5 in IPF‐LF conditioned medium were shown to be higher than Ctrl‐LF conditioned medium (Figure 1E). Here, CCL5 is linked to idiopathic pulmonary fibrosis.
