The absence of effective therapies for EFE stems from a fundamental lack of understanding of its underlying cellular and molecular mechanisms. Progress in investigating EFE pathogenesis has been further constrained by the scarcity of patient-derived samples. Our study directly addresses this critical knowledge gap by performing an integrative multi-omics study—combining single-nucleus RNA/ATAC sequencing and high-resolution spatial transcriptomics (MERFISH) on human EFE and healthy heart tissues.","dates":{"publication":"2026/08/29"},"accession":"GSE315408","cross_references":{"GSM":["GSM9427139","GSM9427137","GSM9427138","GSM9427140","GSM9427141"],"GPL":["31217"],"GSE":["315408"],"taxon":[" synthetic construct","Homo sapiens"]}}
