A new method for preparation of isolated single adult myocytes
1984
A new technique for isolation of single cardiac cells from adult rat ventricles is described. The mechanical method is modified from the method of Jacobson (Cell Struct. Funct. 2: 1-9, 1977) by employing an enzyme-free dispersion medium containing Sr2+ or Ba2+ to replace Ca2+. This method produces a high yield of isolated rod-shaped adult mammalian cardiomyocytes that do not contract spontaneously, have a normal resting potential, and are Ca2+ tolerant. This method represents a promising technique for isolation of single, viable, intact, adult myocytes.
