The vertebrate heart tube forms from epithelial progenitor cells in the early embryo and subsequently elongates by progressive addition of second heart field (SHF) progenitor cells from adjacent splanchnic mesoderm. Failure to maximally elongate the heart results in a spectrum of morphological defects affecting the cardiac poles, including outflow tract alignment and atrioventricular septal def...
Background: In this study, we examined a new two step induction protocol for improving the differentiation of human umbilical cord blood-derived mesenchymal stem cells into neural progenitor cells. Materials and Methods: Human umbilical cord blood-derived mesenchymal stem cells were first cultured in Dulbecco’s modified eagle medium supplemented with 10% fetal bovine serum in a humidified incu...
BACKGROUND A major hurdle in the use of exogenous stems cells for therapeutic regeneration of injured myocardium remains the poor survival of implanted cells. To date, the delivery of stem cells into myocardium has largely focused on implantation of cell suspensions. METHODOLOGY AND PRINCIPAL FINDINGS We hypothesize that delivering progenitor cells in an aggregate form would serve to mimic th...
Generation of new cardiomyocytes is critical for cardiac repair following myocardial injury, but which kind of stimuli is most important for cardiomyocyte regeneration is still unclear. Here we explore if apoptotic stimuli, manifested through caspase activation, influences cardiac progenitor up-regulation and cardiomyocyte differentiation. Using mouse embryonic stem cells as a cellular model, w...
Heart disease can be caused by many different insults and injuries and often terminates in death from heart failure, an inability of the heart muscle to adequately supply blood to the body. A major aim in today’s research is to define novel therapeutic strategies to limit myocardial damage and to enhance the ability of the heart muscle to regenerate and to heal itself. The anti-cancer drug doxo...
