Abstract
Fertile X. laevis eggs were immobilized so that they were prevented from undergoing the rotation response to activation. Many of those unrotated eggs developed through organogenesis, indicating that egg rotation is not a prerequisite for normal early embryogenesis. Various aspects of the regulation of pattern formation were analyzed in unrotated eggs. A substantial rearrangement of yolk platelets occurred without affecting subsequent pattern formation. The germ plasm remained localized in the vegetal hemisphere in inverted eggs. Cleavage furrows and the site of involution were often observed in novel locations in inverted eggs which were prevented from rotating during activation.This publication has 12 references indexed in Scilit:
