CTHRC1 and idiopathic pulmonary fibrosis: We identified several genes that exhibited the most significant changes in expression during pseudotime progression in IPF-fibroblasts, including collagen triple helix repeat-containing protein 1 (CTHRC1), dermatopontin (DPT), inhibitor beta A chain (INHBA), and latent-transforming growth factor beta-binding protein 1 (LTBP1) (Figure 3D–F).
