Cinematographic observation of “surface contraction waves” (SCW) during the early cleavage of axolotl eggs

Short Communication


Prior to the appearance of the cleavage furrows circular or semicircular zones suggesting surface contraction originate at the future initiation point of the cleavage furrow. They expand and travel in animal-vegetative direction.
