1 a head and tail form Most animal species have regenerated tissues lost by injury with various degrees of success and some of these animals display extraordinary regenerative capacities Wnt signaling is an important and crucial signal in the whole life of animals because it helps the animal to regenerate fro early life to adulthood In intact and regenerating planarians the regulation of the Wntcatenin signaling function is to maintain and specify anteriorposterior AP identity according to one study of the planaria by the group of scientist they experimented the same inhibiting the center part of the planarian body they found the genes which are found that is for wnt have a complete absence of stem cells and despite a strong induction See Answer
