Interestingly, three of the novel hubs, CRABP2, CDH3, and DCLK1 are found to be expressed in aberrant basaloid cells, a novel epithelial cell population that co-express basal epithelial markers and are located at the edge of myofibroblast loci in the IPF lung [18,22] (Figure 3D,E). This evidence concerns the gene CDH3 and idiopathic pulmonary fibrosis.
