"we used an
unc-119::GFP transgenic reporter uniquely expressed in multiple neurons in wild-type animals (Ciosk et al., 2006) and antibodies specifically recognizing muscle cells. We observed that a subset of the abnormal nuclei in
set-2 mutant germlines expressed the
unc-119::GFP reporter, the body wall muscle marker UNC-120 (a MADS box factor), or myosin (Figures 2C, 2D, and S2B).
unc-119::GFP expression was often observed in cells with extensions resembling axodendritic projections (Figure 2C). Only 18% (4/22) of germlines expressing neuronal GFP also expressed UNC-120, while all germlines expressing UNC-120 were also positive for neuronal GFP. By contrast, ELT-2, a marker of intestinal differentiation, was not observed in either neuronal GFP-expressing (n = 30) or not expressing(n = 32; Figure S2C) germlines."
