The ability of restoration of the whole worm from a small body fragment was not reduced after 8 removals of the anterior and posterior regenerates. The polarity of restoring fragments in the most cases corresponded to the initial one. Upon the colchicine effect on the restoring fragments which accompanied the repeated removal of the regenerates, a high percentage of cases of incomplete somatic embryogenesis was observed: the formation of bi- and multipolar forms. The formation of regenerates is realized by neoblasts. Upon the repeated removal of regenerates, the dedifferentiated intestine cells appear to take part in the restorative processes as well.
在前后再生体被切除8次后，小身体片段恢复成完整蠕虫的能力并未降低。在大多数情况下，恢复片段的极性与初始极性一致。在用秋水仙碱作用于伴随再生体反复切除的恢复片段时，观察到高比例的不完全体细胞胚胎发生情况：形成双极和多极形式。再生体的形成是由新生细胞实现的。在再生体被反复切除后，去分化的肠细胞似乎也参与了恢复过程。
