The bioluminescent photoprotein, aequorin, can measuTe fast Ca '+ transients, but its sensitivity is poor for measuring resting [Ca'']i (1,25): A Ca"-sensitive microelectrode can detect resting [Ca-']i levels, but the measuTements aTe subject to various degrees of error due to impalernent damage (5,18,21). The nullpoint titration method using arsenazo III can

Ratiometric intracellular calcium imaging in the isolated beating rat heart using indo-1 fluorescence.
Abnormalities in intracellular calcium (Ca(i)(2+)) handling have been implicated as the underlying mechanism in a large number of pathologies in the heart. Study into the relation between Ca(i)(2+) behavior and performance of the whole heart function could provide detailed information into the cellular basis of heart function. In this study we describe an optical ratio imaging setup and an anal...
متن کاملContractile arrest increases sarcoplasmic reticulum calcium uptake and SERCA2 gene expression in cultured neonatal rat heart cells.
We developed protocols with intact cultured neonatal rat myocytes to directly evaluate the function of the sarcoplasmic reticulum (SR) Ca-ATPase (or SERCA2), Na-Ca exchange (Na-CaX), and slow Ca transport systems (mitochondria and sarcolemmal Ca-ATPase). Spontaneously beating control cells were compared with cells cultured for 2 days in the presence of verapamil (verapamil-arrested cells, VA). ...

Scaduto, Russell C., Jr., and Lee W. Grotyohann. Hydrolysis of Ca2 -sensitive fluorescent probes by perfused rat heart. Am J Physiol Heart Circ Physiol 285: H2118–H2124, 2003; 10.1152/ajpheart.00881.2001.—Rat hearts were loaded with the fluorescent calcium indicators fura 2, indo 1, rhod 2, or fluo 3 to determine cytosolic calcium levels in the perfused rat heart. With fura 2, however, basal ti...
متن کاملCytosolic Ca2+ concentration decreases in diabetic rat myocytes.
Diabetes mellitus has been shown to be associated with heart failure of unknown origin, which is termed ‘diabetic w x w x cardiomyopathy’ 1 . Regan et al. 2 have shown that the small vessel lesions in diabetes mellitus have little or no relation to diabetic cardiomyopathy, suggesting that the contractile function of the diabetic cardiomyopathy was primarily defective. Although many studies have...
متن کاملEvaluation of Chronotropic Properties of Mouse Embryonic Stem Cells-Derived Cardiomyocytes After Fibroblast Growth Factor Treatment
Purpose: We investigated the effect of (bFGF) (basic-Fibroblast Growth Factor) on the differentiation of divided cardiomyocytes from mouse embryonic stem cells (ES) and their pharmacological properties. Materials and Methods: The mouse embryonic stem cells (Royan B1) were cultured as 800 cells per 20µl of a hanging drop. After two days, ES cells in each drop aggregated to form embryoid bodies ...
