Summary
-
1.
Smooth mucle cells from the taenia coli of the guinea-pig have been grown in tissue culture.
-
2.
Intracellular recordings from clumps of cells showed spontaneous spikes of variable height, associated with slow waves. Cells in clumps appeared to be electrotonically coupled to their neighbours.
-
3.
Single isolated cells also generated spontaneous spikes and slow waves. Spikes from these cells were of nearly constant height.
