(Submitter supplied) The adult mammalian heart has limited capacity for regeneration following injury, whereas the neonatal heart can readily regenerate within a short period after birth. Neonatal heart regeneration is orchestrated by multiple cell types intrinsic to the heart, as well as immune cells that infiltrate the heart after injury. To elucidate the transcriptional responses of the different cellular components of the mouse heart following injury, we performed single cell RNA-sequencing on neonatal hearts at various time points following myocardial infarction, and coupled the results with bulk tissue RNA-sequencing data collected at the same time points. more...

(Submitter supplied) Background: The adult mammalian heart has limited capacity for regeneration following injury, whereas the neonatal heart can readily regenerate within a short period after birth. To uncover the molecular mechanisms underlying neonatal heart regeneration, we compared the transcriptomes and epigenomes of regenerative and non-regenerative mouse hearts over a 7-day time period following myocardial infarction. more...

(Submitter supplied) Background - The inability of the adult mammalian heart to regenerate following injury represents a major barrier in cardiovascular medicine. In contrast, the neonatal mammalian heart retains a transient capacity for regeneration, which is lost shortly after birth. Defining the molecular mechanisms that govern regenerative capacity in the neonatal period remains a central goal in cardiac biology. Here, we construct a transcriptional atlas of multiple cardiac cell populations, which enables comparative analyses of the regenerative (neonatal) versus non-regenerative (adult) state for the first time. more...

(Submitter supplied) The adult mammalian heart is incapable of regeneration following injury. In contrast, the neonatal mouse heart can efficiently regenerate during the first week of life. The molecular mechanisms that mediate the regenerative response and its blockade in later life are not understood. Here, by single-nucleus RNA sequencing, we map the dynamic transcriptional landscape of five distinct cardiomyocyte populations in healthy, injured and regenerating mouse hearts. more...

(Submitter supplied) Background: Current mammalian model for heart regeneration research is limited in apex amputation or myocardium infarction, both of which are controversy. Moreover, RNAseq demonstrated there were a very limited set of differential expressed genes between sham and operation heart in the myocardium infarction model. Here we investigated whether pressure overload in the right ventricle(RV), a common phenomenon in congenital heart disease children, could be a better animal model for heart regeneration study when consider cardiomyocyte(CM) proliferation as the most important index. more...

(Submitter supplied) The goal of the present study is to determine the miRNA cargo present in epicardial extracellular vesicles. For that, epicardial cells and human primary epicardial cells were cultured. Conditioned media was isolated from mouse epicardial cells and human primary epicardial cells derived from right atrial appendages in two different states: “cobble” (inactive) cells and “spindle” (active) . RNA from EVs was isolated and sequenced to determine the miRNA content profile.

(Submitter supplied) Rationale: Neonatal mice have the capacity to regenerate their hearts in response to injury, but this potential is lost after the first week of life. The transcriptional changes that underpin mammalian cardiac regeneration have not been fully characterized at the molecular level. Objective: The objectives of our study were to determine if myocytes revert the transcriptional phenotype to a less differentiated state during regeneration and to systematically interrogate the transcriptional data to identify and validate potential regulators of this process. more...

(Submitter supplied) Myocardial infarction (MI) leads to cardiomyocyte death, which triggers an immune response that clears debris and restores tissue integrity. In the adult heart, the immune system facilitates scar formation, which repairs the damaged myocardium but compromises cardiac function. In neonatal mice, the heart can regenerate fully without scarring following MI; however, this regenerative capacity is lost by P7. more...

(Submitter supplied) A better understanding of the pathways that regulate regeneration of the coronary vasculature is of fundamental importance for the advancement of strategies to treat patients with heart disease. By analyzing single cell transcriptome of resident cardiac endothelial cells (ECs) in adult mouse hearts under both healthy and myocardial infarction (MI) settings, we provide molecular definitions of murine cardiac endothelial heterogeneity and characterizations of pro-angiogenic resident ECs.

(Submitter supplied) Backgound: Cardiac pressure overload, for example in patients with aortic stenosis, induces irreversible damage in the myocardium leading to cardiac dysfunction, cardiomyocyte hypertrophy and interstitial fibrosis. We therefore hypothesized that insufficient cardiac regeneration might contribute to the progression of pressure overload dependent disease. Here, we aimed to elucidate whether pressure overload in the regenerative stage shortly after birth could lead to a more adaptive cardiac response than in the non-regenerative stage in mice.nTAC in the non-regenerative stage induced cardiac dysfunction, myocardial fibrosis and cardiomyocyte hypertrophy. more...
