title: Chemically mediated cell-to-cell contractile activation in isolated frog atrial cardiac cells.
abstract: A dying single frog atrial cardiac cell liberates an unknown substance which diffuses away from the dying cell and activates contractile activity in other isolated intact single cardiac cells within the vicinity of the dying cell.
