In animals raised under normoxia, the nhr- 57::gfp reporter was weakly expressed in several somatic cells including the intestinal cells, but not in the VPCs before VI. After the first round of VPC divisions in mid-L3 larvae,
nhr-57::gfp expression became visible in the descendants of the uninduced distal VPCs but remained undetectable in the descendants of the induced proximal VPCs until they had completed their last round of division and terminally differentiated.
