Demonstration of the dorsal character of the body wall of the aneurogenic regenerate of Nereis pelagica L. (Annelida, Polychaeta)

Demonstration of the dorsal character of the body wall of the aneurogenic regenerate of Nereis pelagica L. (Annelida, Polychaeta)

In Nereis pelagica, graft of dorsal or ventral parts of a regenerate edified in the absence of nerve cord (=aneurogenic) on the ventral or dorsal face of a normal host demonstrates a completely dorsal nature of the body wall in these special regenerates. The results indicate that the nerve cord is i...

Description
Summary:In Nereis pelagica, graft of dorsal or ventral parts of a regenerate edified in the absence of nerve cord (=aneurogenic) on the ventral or dorsal face of a normal host demonstrates a completely dorsal nature of the body wall in these special regenerates. The results indicate that the nerve cord is involved in setting up regenerate dorso-ventral polarity by fixing differentiation of the ventral characters in the area located near by; without it , only the dorsal character is expressed.
