Samples were collected from IPF upper lobe, IPF lower lobe, and age-matched control lung tissue and processed using the 10x Genomics Chromium platform. Unsupervised clustering identified six transcriptionally distinct mesenchymal subtypes — alveolar, adventitial, inflammatory, CTHRC1⁺, peribronchial and smooth muscle cell — across conditions. Differential gene expression, pathway enrichment, and cell-cell communication analyses were performed to characterize subtype-specific transcriptional programs, ECM remodeling signatures, and intercellular signaling networks in the fibrotic lung niche. CTHRC1⁺ fibroblasts emerged as a dominant fibrogenic hub in IPF, characterized by elevated fibrillar collagen expression, broad outgoing signaling through collagen, fibronectin, and periostin pathways, and spatial co-localization with fibroblastic foci. This dataset provides a transcriptional resource for investigating mesenchymal heterogeneity and fibrogenic cell states in human pulmonary fibrosis.</description><dates><publication>2026/05/29</publication></dates><accession>GSE331144</accession><cross_references><GSM>GSM9739687</GSM><GSM>GSM9739688</GSM><GSM>GSM9739689</GSM><GSM>GSM9739690</GSM><GSM>GSM9739691</GSM><GSM>GSM9739692</GSM><GSM>GSM9739693</GSM><GSM>GSM9739694</GSM><GSM>GSM9739695</GSM><GPL>24676</GPL><GSE>331144</GSE><taxon>Homo sapiens</taxon></cross_references></HashMap>
