Circus Movement

Circus movements have been mainly observed in embryonic blastomeres, neuroectoderm and paraxial mesoderm [1], where a single bleb repeatedly propagates around the circumference of the cell with a period of 1–2 minutes. The cortical actin network reforms asymmetrically during the repolymerization phase of circus movements [2]. This movement requires actomyosin contractility [1][3][4].
