KRT8 and idiopathic pulmonary fibrosis: The transitional stem cell state in lung injury repair is also characterized by increased levels of KRT8 expression (Strunz et al, 2020), and interestingly, we found that cells with increased levels of KRT8 in metaplastic epithelial areas in IPF lung also co‐expressed increased levels of SFN compared to controls (Fig 6J).
