Abstract

The addition of cortisol acetate and deoxycorticosterone acetate to cultured heart cells from rats, 4 to 6 days old, stimulated and prolonged beating. Protein synthesis was slowed down in the presence of steroids. Addition of steroids to cells that had stopped beating caused the reestablishiment of the beat.
