Sensitivity of cultured chick embryo heart cells to acetylcholine. Evidence for nicotinic and muscarinic receptors.
Sensitivity of cultured chick embryo heart cells to acetylcholine changes with time in culture. In 24 h cultures, about 25% of the cells exhibit a positive chronotropic response to acetylcholine. This effect is no longer observed after 48 h in culture. Positive and negative chronotropic effects of acetylcholine can be related to the presence of nicotinic and muscarinic receptors evidenced by autoradiography. Some data suggest a possible relationship between the type of sensitivity to acetylcholine and the changes in cell membrane properties occurring in culture.
