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.
在培养中，单个、分离的大鼠心脏细胞以不同的速率跳动。当它们生长为物理接触时，跳动变得同步。细胞数量的增加导致纤维状块状物的跳动形成。看来，直接的物理接触对于获得同步收缩是必要的。
