Cell-cell interactions are crucial for organ development and function. In the heart, endothelial cells engage in bidirectional communication with cardiomyocytes regulating cardiac growth. We aimed to elucidate organotypic of cardiomyocyte cell crosstalk using human induced pluripotent stem (hiPSC). Single-cell RNA sequencing was performed hiPSC-derived (hiPS-CMs) (hiPS-ECs) mono- co-culture. The presence hiPS-CMs led increased expression transcripts related vascular maturation, development, as well endocardium-specific genes hiPS-ECs. Interestingly, co-culture myofibrillar MYL7 MYL4 protein detected Major regulators BMP- Notch-signaling pathways were both types These results reflect findings from animal studies extend them cells, demonstrating importance EC-CM during development.

Abstract The heart, which is the first organ to develop, highly dependent on its form function 1,2 . However, how diverse cardiac cell types spatially coordinate create complex morphological structures that are crucial for heart remains unclear. Here we integrated single-cell RNA-sequencing with high-resolution multiplexed error-robust fluorescence in situ hybridization resolve identity of develop human heart. This approach also provided a spatial mapping individual cells enables illumination their organization into cellular communities distinct structures. We discovered many these further specified subpopulations exclusive specific communities, support specialization according ecosystem and anatomical region. In particular, ventricular cardiomyocyte displayed an unexpected laminar across wall formed, other subpopulations, several communities. Interrogating cell–cell interactions within using vivo conditional genetic mouse models vitro pluripotent stem systems revealed multicellular signalling pathways orchestrate during morphogenesis. These detailed findings social constructing remodelling offer new insights structural diseases engineering tissues repair.

The treatment of functional tricuspid regurgitation (TR) is still controversial. Characterizing the cellular composition valve and identifying molecular alterations each cell type in valves with TR will advance our understanding mechanisms guide improvements treatment. authors aimed to investigate changes gene expression patterns cells regurgitant shed light on TR. To improve pathogenesis TR, we performed single-cell RNA sequencing from 10 patients, including 5 patients moderate-to-severe nondiseased control subjects. Multiplexed fluorescence was used detect spatial distributions valvular states validated cell-cell interaction.

Congenital heart disease (CHD) is the most common human birth defect and remains a leading cause of mortality in childhood. Although advances clinical management have improved survival children with CHD, adult survivors commonly experience cardiac non-cardiac comorbidities, which affect quality life prognosis. Therefore, elucidation genetic etiologies CHD not only has important implications for counseling patients families but may also impact outcomes by identifying at-risk patients. Recent advancements technologies, including massively parallel sequencing, allowed discovery new CHD. variant prioritization interpretation pathogenicity remain challenges field genomics, single-cell genomics functional using cellular animal models potential to provide novel insights into underlying mechanisms its associated morbidities.

Abstract Heart organoids have the potential to generate primary heart-like anatomical structures and hold great promise as in vitro models for cardiac disease. However, their properties not yet been fully studied, which hinders wide spread application. Here we report development of differentiation systems ventricular atrial heart organoids, enabling study diseases with chamber defects. We show that our chamber-specific comprising major cell types, use single RNA sequencing together sample multiplexing characterize cells generate. To end, developed a machine learning label transfer approach leveraging type, chamber, laterality annotations available human fetal cells. then used this model analyze organoid from an isogeneic line carrying Ebstein’s anomaly associated genetic variant NKX2-5 , successfully recapitulated disease’s atrialized In summary, established workflow integrating computational analysis normal disease states.
