Single-cell RNA sequencing of hiPSC-derived cardiac organoids patterned toward chamber-specific fates (left ventricle, right ventricle, atrium)
Ontology highlight
ABSTRACT: Summary Single-cell RNA sequencing was performed on cardiac organoids differentiated from WTC11 hiPSCs (TTN-mEGFP) to investigate chamber-specific lineage commitment. Organoids were collected at day 7.5 of differentiation, using protocols designed to direct progenitors toward left ventricle, right ventricle, or atrium fates. This dataset enables the characterization of transcriptional programs and cellular heterogeneity underlying the early specification of the cardiac chamber. Dataset: This dataset contains single-cell RNA sequencing (scRNA-seq) data generated to compare the development of cardiac organoids differentiated from WTC11 hiPSCs (TTN-mEGFP reporter line). Organoids were harvested at day 7.5 of differentiation, a stage at which chamber-specific programs begin to emerge. Each sample corresponds to a distinct differentiation protocol designed to direct the commitment of progenitors toward a specific cardiac chamber identity: the left ventricle, the right ventricle, or the atrium. The experimental rationale, illustrated in Supplementary Figure 4 (Figure S4) of Becca et al. (2025), highlights the use of scRNA-seq to resolve the cellular heterogeneity of these chamber-directed organoids and to define transcriptional signatures associated with early cardiac chamber specification.
