Genetic analysis of developmental mechanisms in hydra. XXI. Enhancement of regeneration in a regeneration-deficient mutant strain by the elimination of the interstitial cell lineage.

Abstract excerpt

The interstitial cell lineage, including interstitial stem cells, nerve cells, and nematocytes, was eliminated from a regeneration-deficient mutant strain (reg-16) of Hydra magnipapillata. The resultant interstitial cell lineage-free (or "epithelial") reg-16 animals showed a marked enhancement in the ability to regenerate head structures. The epithelial reg-16 polyps regenerated nearly the same number of...
