To investigate Wnt/PCP signaling we studied expression and localization of DAAM1 (Figs. 3B, 4), which was significantly increased (P < 0.01) in normal‐looking parenchyma (227 ± 66 cells/mm2), border zones (1320 ± 257), and dense fibrosis (320 ± 69) in IPF patients compared to healthy donors (104 ± 60 cells/mm2). The gene discussed is DAAM1; the disease is idiopathic pulmonary fibrosis.
