[Emergence of contraction waves on the surface of fertilized frog eggs under the effect of inositol triphosphate].
It was shown that the injection of the membrane messenger-myo-inositoltrisphosphate into frog eggs provokes the propagation of surface contraction waves. Such waves are not accompanied by the changes of membrane potential. We have analyzed the spatial-temporal characteristics of observed waves and have compared them with the data from models for diffusion and autocatalytic mechanisms of wave propagation.
