Cinematographic observation of an "activation wave" (AW) on the locally inseminated egg ofXenopus laevis.

Koki Hara1, Peter Tydeman1.   

Abstract

Shortly after local artificial insemination, but well before egg rotation,Xenopus eggs show a wave-like propagation of dark-light-dark zones from the site of sperm entrance. This presumably reflects the movement of the front of cortical granule breakdown.
