Mitotic activity in the regenerating respiratory tree was studied in the holothurian Apostichopus japonicus after evisceration. Significant proliferation was recorded in the regenerating tissues. The highest number of mitoses was revealed in the inner epithelium, the mitotic index (MI) of which reached 3.44 ± 0.01% on the 10th day of regeneration, which was comparable to MI values of blastema of a regenerating amphibian limb. In the coelomic epithelium the number of dividing cells varied from 0.49% in the upper part (20th day) up to 2.87% in the base (10th day). The proliferative activity gradually decreased in the further course of regeneration. In spite of high MI values, the distribution of mitoses in tissues was even at all stages of regeneration and blastema did not form.
