Abstract Gunasekaran et al demonstrate that human neonatal Mesenchymal Stem Cells (nMSCs) evade from macrophage mediated phagocytosis via increased CD47 expression and to promote functional recovery by secretion of exosomes and independent cytokines. The increased...

Abstract The stem cell field is hindered by its inability to noninvasively monitor transplanted cells within the target organ in a repeatable, time-sensitive, and condition-specific manner. We hypothesized that quantifying and characterizing transplanted cell–derived...

Abstract Hypoplastic left heart syndrome is a type of congenital heart disease characterized by underdevelopment of the left ventricle, outflow tract, and aorta. The condition is fatal if aggressive palliative operations are not undertaken, but even after the complete...

Abstract One of the most complex forms of congenital heart disease (CHD) involving single ventricle physiology is hypoplastic left heart syndrome (HLHS), characterized by underdevelopment of the left ventricle (LV), mitral and aortic valves, and narrowing of the...

Abstract Pregestational maternal diabetes induces congenital heart defects (CHDs). Cardiac dysfunction after palliative surgical procedures contributes to the high mortality of CHD patients. Autologous or allogeneic stem cell therapies are effective for improving...

Abstract Rationale—Cardiac progenitor cells are an attractive cell type for tissue regeneration but their mechanism for myocardial remodeling is still unclear. Objective—This investigation determines how chronological age influences the phenotypic characteristics and...

Abstract Stem cell hypothesis of aging postulates that youthful stem cells have better intrinsic ability to repair/regenerate after an injury. Consistent with this hypothesis, current report by Sharma et al observed nCPCs transplantation post-MI was associated with...

Abstract Stem cell therapy has the optimistic goal of regenerating the myocardium as defined by regrowth of lost or destroyed myocardium. As applied to patients with heart failure, many confuse or limit the regenerative definition to just improving myocardial function...

Abstract Background—We sought to determine the location, expression, and characterization of cardiac stem cells (CSCs) in children with end-stage heart failure (ESHF). We hypothesized ESHF myocardium would contain an increased number of CSCs relative to age-matched...

Abstract We have demonstrated that human neonatal cardiosphere derived cells (CDCs) derived from the young are more regenerative due to their robust secretome. However, it is unclear how the decompensated pediatric heart impacts the functional activity of their CDCs....
