Electrophysiological coupling of transplanted cardiomyocytes.
The recent advances in stem cell biology and tissue engineering have paved the way to the development of a new field in biomedicine, regenerative medicine. This approach seeks to circumvent the shortage of organs for transplantation, by combining the above-mentioned technologies in an attempt to replace diseased or absent tissue. The heart represents an attractive candidate for these emerging t...
متن کاملElectrophysiological integration and action potential properties of transplanted cardiomyocytes derived from induced pluripotent stem cells.
AIMS Induced pluripotent stem cell-derived cardiomyocytes (iPSCM) are regarded as promising cell type for cardiac cell replacement therapy. We investigated long-term electrophysiological integration and maturation of transplanted iPSCM, which are essential for therapeutic benefit. METHODS AND RESULTS Murine iPSCM expressing enhanced green fluorescent protein and a puromycin resistance under c...
متن کاملModeling Electrophysiological Coupling and Fusion between Human Mesenchymal Stem Cells and Cardiomyocytes
Human mesenchymal stem cell (hMSC) delivery has demonstrated promise in preclinical and clinical trials for myocardial infarction therapy; however, broad acceptance is hindered by limited understanding of hMSC-human cardiomyocyte (hCM) interactions. To better understand the electrophysiological consequences of direct heterocellular connections between hMSCs and hCMs, three original mathematical...
متن کاملElectrophysiological abnormalities in the transplanted human heart.
Fourteen relatively long term survivors of cardiac transplantation underwent systematic electrophysiological evaluation and ambulatory electrocardiographic monitoring. Six patients had prolonged conduction intervals during sinus rhythm. Sinus node function could be assessed in all donor atria and in 10 recipient atria. Sinus node recovery times were prolonged in four of the donor atria and in s...
متن کاملElectrophysiological characterization of murine HL-5 atrial cardiomyocytes.
HL-5 cells are cultured murine atrial cardiomyocytes and have been used in studies to address important cellular and molecular questions. However, electrophysiological features of HL-5 cells have not been characterized. In this study, we examined such properties using whole cell patch-clamp techniques. Membrane capacitance of the HL-5 cells was from 8 to 62 pF. The resting membrane potential wa...
