title: In vitro Organization of Single Beating Rat Heart Cells into Beating Fibers.
abstract: Single, separate rat-heart cells in culture beat at different rates. When they grow into physical contact the beating becomes synchronous. Increase in cell number leads to the formation of beating, fiber-like masses. It appears that direct physical contact is necessary for attainment of synchronous contractions.
