Nine sections (one per patient, 3 per group; 625,305 cells) were profiled with a 477-gene panel. Part of a multimodal atlas that also includes bulk RNA-seq, single-nucleus RNA-seq and a murine pulmonary artery banding model.2026/09/04GSE345643GSM10012170GSM10012172GSM10012171GSM10012174GSM10012173GSM1001217533762345643Homo sapiens
