"Wild-type hermaphrodites have one anchor cell that can be detected using a
lin-3::lacZ or
cdh-3::GFP reporter transgene (Hill and Sternberg, 1992; Pettitt et al., 1996).
cki-1(RNAi) animals display more than one anchor cell since multiple cells stain for
lin-3::lacZ and show
cdh-3::GFP expression (Fig. 1E; data not shown)."
