Idiopathic pulmonary fibrosis (IPF), a deadly lung disease of unclear etiology, lacks sufficient therapeutic options. We extensively mapped the spatial transcriptomes of patient lungs and made translational comparisons with a mouse model of lung fibrosis, providing insights into disease mechanisms and the utility of the animal model for drug discovery.
