Cardiac Muscle Cells in Culture,. Until the 1950’s, most of the studies involved explant culture and the modification of nutrient medium to maintain the cells in a differentiated, contractile state (see . 1965). In 1955 . enzymatically dispersed cardiac muscle into single cells and systematically observed their behaviour.

The Conduction System, into a well-defined mass. The location and extent of the SA node varies slightly between mammalian species. In the rabbit, cat, mouse, rat, guinea-pig and monkey, the SA node is located in the wall of the superior vena cava (SVC), above or extending down to the crista terminalis (. and . 1973 a; .

Development of the Conduction System,and an immature conduction system produce similar wave patterns. Cardiac electrical activity has been recorded from chick embryos as early as stage 24 (. et al. 1939; . and . 1951) and stage 16 (. et al. 1981) (Fig. 85), when no morphologically definable conduction system is present and the outward

Regeneration,(. 1969; . 1970; . 1971; . 1977, 1981). This loss of regenerative ability is due to an irreversible withdrawal of the cardiac myocyte from the cell cycle (. 1980) and the fact there are no satellite cells present as in skeletal muscle (. 1979; . 1985).
