Repeated cleavage failure does not establish centrosome amplification in untransformed human cells

Abstract excerpt

We tested whether cleavage failure as a transient event establishes an incidence of centrosome amplification in cell populations. Five rounds of ∼30% cytochalasin-induced cleavage failure in untransformed human cell cultures did not establish centrosome amplification in the short or long terms. The progeny of binucleate cells progressively dropped out of the cell cycle and expressed p53/p21, and none divided a...
