A LIM-homeobox gene is required for differentiation of Wnt-expressing cells at the posterior end of the planarian body

Planarians have high regenerative ability, which is dependent on pluripotent adult somatic stem cells called neoblasts. Recently, canonical Wnt/β-catenin signaling was shown to be required for posterior specification, and Hedgehog signaling was shown to control anterior-posterior polarity via act…
