The effects of ectoteloblast ablation in the earthworm

KG Storey

The effects of ablating individual earthworm embryo were studied in terms of the morphology of the ventral and a discrete population of histochemically present in each segment of the worm. The activity of the vicinity of the ablated teloblast was assessed by pattern of cells undergoing DNA synthesis for up to ablation. While examination of the morphology of the mounts suggests that a reconstitutive process is ectoteloblast ablation, this is not borne out in level of individual, histochemically identified cells, hatching stage appeared to be missing following ectoteloblasts. A proliferative response to ablation cells in the vicinity of the ablated teloblast, some reconstitutive process(es) operate in this do not result in a completely normal nerve cord at the
