Fundamentals of planarian regeneration.

Because blastemas do not replace all tissues following most types of injuries, both blastema formation and morphallaxis are needed for complete regeneration. Here we discuss a proliferative cell population, the neoblasts, that is central to the regenerative capacities of planarians.

We identify the types of structures produced by blastemas on a variety of wound surfaces, the principles planarin the reorganization of pre-existing tissues, and the manner in which scale and cell number proportions between body regions are restored during regeneration. Planarian regeneration involves the generation of new tissue at the wound site via cell proliferation blastema formationand the remodeling of pre-existing tissues to restore symmetry and proportion morphallaxis.
