In situ hybridization images on embryonic, larval, and adult worms with vha-7 (M-P) are shown. vha-7 is not expressed in embryos and young larvae (M). Expression starts at the L3-L4 larval stage (N) and is seen in early oocytes (arrow) and in the spermateca (arrowhead) in L4 (O) and adult (P).

MEC-2 Localization. The right panel shows the enlarged portion corresponding to each boxed area on the left.(A) MEC-2 puncta in PLM (lateral, l) and PVM (ventral, v) processes. The average distances between puncta in different touch receptor neuron processes were ALM: 3.4 ± 0.2 μm (mean ± SEM, n = 17), PLM: 4.3 ± 0.2 μm (n = 16), AVM: 3.2 ± 0.2 μm (n = 9), and PVM: 2.9 ± 0.1 μm (n = 10).(B) MEC-2 (red) and MEC-4::YFP (green) puncta colocalize in an ALM touch receptor neuron in a young adult.

over-expressed (OE) TSP-12::GFP (I, K, M, O) in the early embryo (A), L4 developingvulva (C), late L3 hypodermis (E), young adult gonad (G), L3 larva head (I), L4 intestine (K: basolateral focal plane of the intestine and the arrow points to the lateral membrane, M: middle focal plane of the intestine andthe arrow points to the apical lumen of the intestine), and L3 neurons (O). (Q and R) L1 transgenic animalscarrying both over-expressed TSP-12::GFP and the M lineage specific reporter hlh-8p::NLS::mCherry. TSP12::GFP is present in M lineage cells from 1-M (Q) to 8-M (R) stages. Some M lineage cells are out of the focalplanes shown. Scale bars represent 10um in A-R. (S) Rescue of the small body size of tsp-12(ok239); tsp-14(jj95) worms produced by tsp-12(ok239)/+; tsp-14(jj95) mothers using tissue-specific tsp-12 cDNAexpression. The mean body length of WT worms is normalized to 1.0. Error bars represent 95% confidenceintervals for the normalized body length.

(A) Developmental Northern blot of total RNA from populations of C. briggsae XX animals. M, mixed ages; L1 to L4, four larval stages; yA, young adults; A, adults. We used a probe for 18s ribosomal RNA on the same blot to control for variations in loading. The probes are described in materials and methods.
