In this study, single-cell RNA sequencing was performed on endothelial cells isolated from adult wild-type mouse lungs. KIT-positive endothelial cells were stratified into Foxf1-positive capillary endothelial progenitor cells (capEPCs) and Foxf1-negative endothelial cells. Differential gene expression analysis identified Ifitm3 as highly enriched in capEPCs, supporting a role for the FOXF1–IFITM3 pathway in endothelial regeneration and pulmonary fibrosis.2026/08/13GSE341505GSM990791224247341505Mus musculus
