[Regeneration of a whole worm from a small fragment of the body of Dugesia tigrina planaria following repeated removal of regenerates].

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.
