... of ectoteloblast lineages in the oligochaete annelid Tubifex involves cell interaction networks distinct from those in leeches. Cell ablation experiments have shown that fates of teloblasts N, P and Q in Tubifex embryos are determined rigidly as early as their birth. In contrast, the O teloblast and its progeny...

Experiments have revealed a number of cell interactions at this stage that transfer patterning information from cell...

Over-expression of the gene, induced in a stock containing the wg gene under the control of a heat-shock promoter, results in super-numerary cells in the tubules.
