[Stathmokinetic reaction reversibility in malignantly transformed cells]

The statmokinetic reaction of malignant-transformed cells of a hamster tumor (CHT-1) was induced by colcemid. The reversibility of the reaction is primarily related to the repolymerization of spindle microtubules from the tubuline pool of the precursors. The character of the statmokinetic reaction reversibility in the test cells evidences the activity of polymerization processes in them. The course of these processes in the presence of copper ions did not differ from that in nonmalignant-transformed cells.
