(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) 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) Neonate mice and men display a transient cardiac regenerative potential that rapidly declines postnatally. Thus, patients that survive a myocardial infarction (MI) often develop chronic heart failure (HF) as a consequence of this poor myocardial healing capacity. Herein, we hypothesized that the cardiac “regenerative-to-scarring” transition is driven by the developing adaptive immune system.

(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 ability to repair itself following injury. Zebrafish, newts and neonatal mice can regenerate cardiac tissue, largely by cardiac myocyte (CM) proliferation. It is unknown if hearts of young large mammals can regenerate. Methods: We examined the regenerative capacity of the pig heart in neonatal animals (ages: 2, 3 or 14 days postnatal) after myocardial infarction (MI) or sham procedure. more...

(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...

(Submitter supplied) Since the proliferative capacity of cardiomyocytes is extremely limited in the adult mammalian hearts, the irreversible loss of cardiomyocytes following cardiac injury markedly reduces cardiac function, leading to cardiac remodeling and heart failure. However, the early neonatal mice have a strong ability in cardiomyocyte proliferation and cardiac regeneration after heart damage such as apical resection. more...

(Submitter supplied) In this study, we used a cardiac-specific, inducible expression system to activate YAP in adult mouse heart. Activation of YAP in adult heart promoted cardiomyocyte proliferation and did not deleteriously affect heart function. Furthermore, YAP activation after myocardial infarction (MI) preserved heart function and reduced infarct size. Using adeno-associated virus subtype 9 (AAV9) as a delivery vector, we expressed human YAP in the murine myocardium immediately after MI. more...

The hypothesis tested in the present study was that M2-like macrophages in myocardial infarction (MI) heart have upregulation of genes relevant to cardiac repair. The results obtained showed tha various tanti-inflammatory and reparative genes were upregulated in M2-like macrophage from MI heart compared to those from intact hearts. more...

(Submitter supplied) Adverse cardiac remodeling after myocardial infarction (MI) causes structural and functional changes in the heart leading to heart failure. The initial pro-inflammatory response followed by an anti-inflammatory or reparative response post-MI is essential for minimizing the myocardial damage, healing, and scar formation. Bone marrow-derived macrophages (BMDMs) are recruited to the injured myocardium and essential for cardiac repair as they can adopt both pro-inflammatory (M1) or anti-inflammatory/reparative (M2) phenotypes to modulate inflammatory and reparative response, respectively. more...

(Submitter supplied) We generated i4F (Heart) mice which has cardiac-specific and doxycycline (DOX) controllable OSKM expression system. Using next generation sequencing (NGS), we analyzed the whole transcriptomic profiles in isolated adult cardiomyocytes from i4F (Heart) mice, which were under different DOX-treatments. We found the i4F (Heart) mice upon 6 days and 12 days DOX their cardiomycytes had remarkable change of transcriptome to be like neonatal and embryonic cardiomyocytes, which exhibited dedifferentiation, significant change in metabolism, and cell-cycle reactivation. more...
